Darkling Beetles of Berrien County, Michigan

The darkling beetles (Family Tenebrionidae) are the fifth largest family of beetles (Order Coleoptera), with more than 1,300 species in the U.S. and Canada. They are a rather obscure family of relatively small beetles. Most of them are largely or entirely black or dark brown, and many spend a majority of their time hidden away in dark recesses, such as under the bark of dead and decaying trees, under fallen logs, or under rocks. A few are pests in stored food products, such as processed grains.

Perhaps the best known of the darkling beetles is Tenebrio molitor, the larva of which (the common “mealworm”) is sold in pet stores to feed to tropical fish, lizards, and the like. They are also highly touted as food for wild birds; some people even raise their own mealworms for this purpose! Mealworms are also commonly used in classroom science projects.

A provisional list of the darkling beetles of Berrien County was compiled using James C. Dunford et al.’s The darkling beetles of Florida and eastern United States. The list is restricted to species reported from both Michigan and Indiana. Based on the best distributional information currently available, this provisional list of the darkling beetles of Berrien County includes 57 species representing 9 subfamilies and 34 genera.

The darkling beetle fauna of Berrien County represents something less than two-thirds of the more than 85 species known from Michigan, 44 percent of the 129 species known from the western Great Lakes, 25 percent percent of the 225 species known from eastern North America, 4.1 percent of the 1,400 species known from the U.S. and Canada, and 0.3 percent of the 19,000 species described worldwide.

In the following list, States in the western Great Lakes with confirmed records for each species are identified in brackets by 2-letter postal codes (illustrations of most species are available in Dunford et al.):

My Peculiar Reading Habits

One of the nice things about retirement is that it leaves with you more spare time to pursue your interests. One of my interests, beyond birds, is reading. Though still not a prolific reader, by any means, I’ve found the time to read more books in the past year than in any other 12-month period of recent memory. So now, without further ado, brief synopses of the books I’ve read in 2008:

Arnett, Ross H., Jr. 1993. American insects: a handbook of the insects of America north of Mexico. 1st edition. The Sandhill Crane Press, Gainesville, Florida. 850 pp. (This isn’t the kind of book you sit down and read through from cover to cover, but I’ve found it to be an invaluable reference. If you decide to buy this book, make sure you purchase the 1st edition, not the 2nd edition linked to above, as the usefulness of the book has been severely compromised in the 2nd edition.)

Berendt, John. 2006. The city of falling angels. Penguin Books, New York, New York. 432 pp. (Mystery and intrigue in the historic city of canals, Venice.)

Delatte, Carolyn E. (with forward by Christoph Irmscher). 2008. Lucy Audubon: a biography. Revised edition. Louisiana State University Press, Baton Rouge, Louisiana. 248 pp. (The little-known story of the woman who supported John James and his family through many trials and tribulations, and helped bring his dream to fruition.)

Kurlansky, Mark. 1998. Cod: a biography of the fish that changed the world. Penguin Books, New York, New York. 304 pp. (It turns out that the history of this fish is inextricably intertwined with that of salt.)

Kurlansky, Mark. 2003. Salt: a world history. Penguin Books, New York, New York. 498 pp. (An exhaustive, if somewhat repetitive, history of this mineral and its influence on world cultures.)

Larkin, Emma. 2004. Finding George Orwell in Burma. Penguin Books, New York, New York. 304 pp. (A unique and frightening insight into what it’s like to live in the world’s most repressive country, where “Orwell’s words . . . continue to resonate.”)

Myers, Robert C. 2003. Lost on the lakes: shipwrecks of Berrien County, Michigan. Andrews University Press, Berrien Springs, Michigan. 277 pp. (An excellent local history of a nautical nature.)

Schroeder, Lucinda Delaney. 2006. A hunt for justice: the true story of a woman undercover wildlife agent. The Lyons Press, Guilford, Connecticut. 270 pp. (Not great literature, but a fascinating behind-the-scenes look at a wildlife sting operation in arctic Alaska.)

Steinberg, Michael K. 2008. Stalking the ghost bird: the elusive Ivory-billed Woodpecker in Louisiana. Louisiana State University Press, Baton Rouge, Louisiana. 173 pp. (Steinberg—a self-proclaimed ‘true-believer’—summarizes the results of a series of interviews with individuals from various walks of life, all of whom claim to have had personal encounters with the IBWO or otherwise believe that it continues to exist in the swamps of Louisiana. Believers will love it, while skeptics will scoff at the lack of scholarship.)

Weidensaul, Scott. 2007. Of a feather: a brief history of American birding. Harcourt. Harcourt, New York, New York. 368 pp. (An engaging and wide-ranging survey of the growth of American birding, from John James Audubon to Roger Tory Peterson and on into the 21st century.)

Bear-ly Tolerable Situation

Charlie Vandergaw, a 70-year-old retired teacher, has been befriending bears (both black and grizzly) on his remote homestead north of Anchorage, Alaska. Now, authorities with the Alaska Department of Fish and Game—who claim that Vandergaw has caused reckless endangerment of the public through a food-conditioning program that has attracted two dozen bears to his property—are considering bringing charges against him. Vandergraw prides himself on being smarter than Timothy Treadwell—who, along with his girlfriend, Amie Huguenard, was famously devoured by one of the Grizzly Bears they had sought to ‘befriend’—and “in better control of his situation.” Only time will tell.

Bald Eagle as a Backyard Bird

Having lived in coastal Alaska for 17 years of my adult life, I was accustomed to seeing Bald Eagles, and lots of them. But I never really expected to see one in Berrien County, Michigan, and certainly not in my own yard, but that's exactly what happened this morning.

Stepping out the front door this morning at 8:00 AM for my morning bird walk, I had an adult Bald Eagle fly directly over our house—on Crescent Lake in Buchanan Township—in flapping flight at fairly low elevation headed in a southerly direction. What a way to start the day!

And later, at about 10:00 AM, as I was mulching leaves in the backyard, I spotted a large, dark bird perched in a tree on the north shore of the lake. Viewing it through binoculars, it proved to be an adult Bald Eagle, presumably the same bird. I judge it to be a 4th-year bird based on the amount of dark smudging on the side of the head, especially the traces of a dark eye-line. The bird remained perched there for about 45 minutes before it disappeared.

Precipitation Summary for October 2008

Daily precipitation was recorded on 24 of 31 days at our home on Crescent Lake, near Buchanan, Michigan, following CoCoRaHS (the Community Collatorative Rain, Hail, & Snow Network) protocols. Cumulative precipitation on the remaining 7 days (October 23-29) was determined from a multi-day report filed on October 29; days on which measurable moisture fell were inferred from precipitation maps.

Precipitation Summary: Measurable amounts of precipitation (i.e., ≥0.01 inches) in the form of rain or snow fell on 17 (55 percent) of 31 days, with a total accumulation (water equivalency) of 3.48 inches (0.11 inches/day, 0.20 inches/day with measureable precipitation). Precipation in the form of snow was recorded on 1 day (October 28th), with a total accumulation of approximately 1.0 inches and a liquid equivalent of 0.30 inches (as determined by a core measurement that was taken 24-hours later).

Comparisons: At CoCoRaHS stations elsewhere in Berrien and surrounding counties, measureable precipitation was recorded on 44.3 percent (360) of 813 reporting days, with values ranging from 34.7 percent (n=129) in St. Joseph County to 62.5 percent (n=40) in Cass County. Rainfall totals at 13 other CoCoRaHS stations in Berien and surrounding counties with 31 consecutive days (or equivalent) of measurements ranged from 3.11 to 3.99 (median 3.48).

Temperature, Relative Humidity, and Dew Point (at 7:00 AM): These readings were recorded on 25 days (October 1-22 and 29-31).

Temperature: High 58 (on 14th), Median 46, Low 30 (on 30th)

Relative Humidity: High 88 (on 8th), Median 79, Low 48 (on 29th)

Dew Point Temperature: High 53 (on 8th), Median 39, Low 19 (on 29th)

Hooktip and False Owlet Moths of Berrien County, Michigan

The hooktip and false owlet moths (Family Drepanidae) are represented in Berrien County, as documented in Sherman Moore’s (1955) Annotated List of the Moths of Michigan (.pdf), consist of just 2 species (representing 2 subfamilies and 2 genera).

The hooktip and false owlet moths of Berrien County represent 9.5 percent of the 21 species known from the U.S. and Canada and 0.6 percent of the approximately 1,000 species known worldwide.

Taxonomic classification and scientific names follow the All-Leps North American Checklist, while common names are from the BugGuide. An asterisk denotes a species documented from Berrien County by Moore:

Giant Silkworm and Royal Moths of Berrien County, Michigan, and Vicinity

The giant silkworm and royal moths (Family Saturniidae) are among the largest and most brightly colored North American members of the Order Lepidoptera (butterflies and moths). Adults of some North American species attain wingspans of up to 140 mm (5.5 in).

Collectively, Sherman Moore’s (1955) Annotated List of the Moths of Michigan (.pdf) and Butterflies and Moths of North America (BaMoNA) list 10 species (representing 3 subfamilies and 9 genera) as having been confirmed in Berrien County plus the neighboring counties of Cass and Van Buren in Michigan and La Porte and St. Joseph in Indiana. Also, another 4 species (representing 2 additional genera) are likely to occur in the region based on their widespread distribution in Michigan and adjacent States (BoMaNA).

In total, then, 14 species representing 3 families and 11 genera have been cofirmed (or are likely to be found) in Berrien County and vicinity. These 14 species represent 82.4 percent of the 17 species documented from Michigan, 18.2 percent of the 77 species found in the U.S. and Canada, and 1.27 percent of the approximately1,100 species known worldwide.

In the following list, species documented from Berrien County are boldfaced, counties with confirmed records are listed in parentheses, and species whose presence is suspected based on their documented occurrence elsewhere in Michigan and surrounding States are in brackets (with indication of States where recorded). Species denoted with an asterisk (*) are from Sherman, those with a hat (^) are from BoMoNA. Scientific and common names follow All-Leps and the Bug Guide.

Hawk Moths and Sphinx Moths of Berrien County, Michigan, and Vicinity

The hawk moths and sphinx moths (Family Sphingidae) are relatively large, colorful, and readily identified members of the Order Lepidoptera (butterflies and moths). Adults of some species so very much resemble hummingbirds in flight (see, especially, the Hummigbird Clearwing) that they are often mistaken as such by lay persons. The moths of this group are recognized as important pollinators.

Collectively, Sherman Moore’s (1955) Annotated List of the Moths of Michigan (.pdf) and Butterflies and Moths of North America (BaMoNA) indicate confirmed records of 18 species (representing 3 subfamilies, and 13 genera) in Berrien County. Plus, BaMoNA lists another 13 species (representing an additional 3 genera) from the neighboring counties of Cass (2) and Van Buren (9) in Michigan and La Porte (5) in Indiana, and another 3 species (representing an additional 2 genera) that are likely to occur in the region based on their widespread distribution in Michigan and other Great Lakes States (BaMoNA).

In total, then, 34 species representing 3 subfamilies and 18 genera have been confirmed (or are likely to be found) in Berkeley County and vicinity. These 34 species represent 85 percent of the 40 species found in Michigan, 27.4 percent of the 124 species found in the U.S. and Canada, and 2.8 percent of the 1,200 species known worldwide.

In the following list, counties with confirmed records are listed in parentheses; species documented from Berrien County are boldfaced; and species whose presence is suspected based on their documented occurrence elsewhere in Michigan and surrounding States are in brakets (with indication of States where recorded). Species denoted with an asterisk (*) are from Sherman, those with a hat (^) are from BaMoNA.

Unusual Field of View

It’s not often that one encounters Wood Ducks and American Robins in the same binocular view, but that’s what happened to me yesterday, probably for the first time in my life. Taking advantage of mild afternoon temperatures (in the high 60s), I put the rowboat in the water and rowed along the northern shoreline of Crescent Lake. Approaching a shallow northwesterly extension of the lake that is surrounded by woods on all sides, I spotted two Wood Ducks in the water very close to shore. I quickly put my binoculars on them and found that they were a pair, a male and female, both in high plumage. I soon realized that, immediately behind the Wood Ducks, on the adjacent shore and between them, was an American Robin. Nervous at my presence, the Wood Ducks slowly inched their way along the shoreline away from me. As they did so, the robin kept pace, hopping along the shore with them. It was amusing to see this unusual pairing of species not usually encountered in the same habitats (or at least not in the same field of view): an American Robin framed stunningly by a pair of Wood Ducks.

Birding and Business

It never occurred to me that there might be skills or strategies employed by top birders that could be adapted by successful business executives to improve the success of their businesses, but the Harvard Business Review claims there are. In 2002, the HBR published an articled entitled Spotting Patterns on the Fly: A Conversation with Birders David Sibley and Julia Yoshida which is still available for purchase. More recently, John Michl of the Thinking Analytically blog has published a series of short posts examining these skill sets, with pattern recognition and randomness being just two of them. I don’t suppose there would be something in here that would help bail out Wall Street?

Birds May Pick Up Chemical Cues from Insect-Damaged Trees

New research out of Finland suggests, not surprisingly, that insectivorous birds are attracted to herbivorous insect-damaged trees. What is surprising is that the birds may be attracted to insect-infested trees not so much by the presence of the insects themselves, as they are by the volatile organic compounds (VOCs) given off by the trees as a protection against insect herbivory.

2008 Blogger BioBlitz—My Results

Damn! I missed the Blogger BioBlitz—for the second year in a row! Either it wasn’t well publicized or I’ve not been keeping up on things, but most likely it was the latter. Luckily, not all is lost. The official dates for the 2008 Blogger BioBlitz were September 20-28. As it happened, I conducted standardized bird counts on seven days during that period, September 20-26, using a protocol defined by eBird as an “area count.” The area that I surveyed included my yard, adjoining Crescent Lake, adjacent scrubby areas, and a hardwoods forest on the opposite side of the lake. Between 1 and 2 hours were devoted to the daily counts.

Rather than submitting my results in the form of a “datasheet download,” I chose to provide a written summary here. I recorded a total of 55 species (min/day: 14, med: 26, max: 42) and a minimum of 1,874 individuals, or 268/day (min: 69, med: 205, max: 595); 17 species were observed just once during the 7 days, while 21 species were observed on 4 or more days.

Project FeederWatch: Database Integrity

I signed up for Project FeederWatch today. I’ve never been a FeederWatch participant, but have always been under the assumption that it was a worthwhile citizen-science project that yielded useful information on winter bird populations.

After signing up, I went to the “Explore Data” section of the FeederWatch web site, as suggested in their press release. Once there, I pulled up a summary for the State of Michigan for 2007-2008. Imagine my surprise upon finding records of Common Ground-Dove (showing an “average group size when seen” of 14.1) and Black-billed Magpie (with an “average group size” of 11.0)! Both of these species are on the Michigan Bird Records Committee’s “Review List.” Their searchable database shows three records of Common Ground-Dove (most recently in 2000) and eight records of Black-billed Magpie (most recently in December 2006-January 2007), with no more than a single individual of each species reported during each sighting.

Other questionable species listed for the 2007-2008 count from Michigan include Mountain Chickadee, Juniper Titmouse, Black-crested Titmouse, Pygmy Nuthatch, Brown-headed Nuthatch, Cactus Wren, and Pyrrhuloxia. Needless to say, there are no confirmed records of any of those species in Michigan.

While I still believe that Project FeederWatch provides useful information on winter populations of common winter birds, internal controls (such as those instituted for eBird and the Great Backyard Bird Count) need to be put into place before such dubious records as those noted above make it into their online database.

Project FeederWatch Benefits Birds and People

Yeah, I know it seems like fall just rolled around. After all, the college football season is less than half over, and I haven’t even raked the leaves in my yard yet. Heck, most of the leaves haven’t even fallen yet. And fall migration is still in full swing.

Be that as it may, the start of the 2008-2009 season for Project FeederWatch is barely more than month away. That’s right, mark your calendars for November 8th and get ready for the all fun and excitement of being a FeederWatcher, while also making a useful contribution to our knowledge of winter bird populations. For information on how to participate, please read this news release from the Cornell Lab of Ornithology:

Ithaca, NY-¬More than 100 studies have shown that getting closer to nature reduces stress and promotes a feeling of well-being in children and adults. So, filling feeders and counting the birds that visit may be just what the doctor ordered! For more than 20 years, that’s what participants in the Cornell Lab of Ornithology’s Project FeederWatch have been doing-¬benefiting themselves and the birds.

"It is a great winter time activity for the whole family," says Alaska FeederWatcher Nancy Darnell. "If you have children, they will come to love watching the birds. All of this is fun and a chance to contribute to scientific studies, too!"

The 2008-09 season of Project FeederWatch gets underway November 8 and runs through April 3. Participants count the numbers and kinds of birds at their feeders each week and send the information to the Cornell Lab of Ornithology. Participants submitted more than 115,000 checklists during the 2007-08 FeederWatch season, documenting unusual bird sightings, winter movements, and shifting ranges-¬a treasure-trove of information that scientists use to monitor the health of the birds and of the environment.

"Being a FeederWatcher is easy and fun, and at the same time helps generate the world’s largest database on feeder-bird populations," says project leader David Bonter. "We are grateful for the contributions our participants have made for the birds and are proud of the joy they say it brings to their busy lives. Since we started in 1987, more than 40,000 people have submitted observations, engaging with the wildlife beyond their windows."

"Project FeederWatch opened up a whole new world for me," says participant Cheri Ryan of Lockport, Kentucky. "It’s so interesting to watch the activities of the birds. I learn something new each time I participate."

Scientists learn something new from the data each year, too, whether it’s about the movements of common backyard birds or unusual sightings of rarely-seen species. Highlights of the most recent season include the largest southward movement of Red-breasted Nuthatches in the history of the project¬-part of an expected influx of northern birds that fly farther south when their food supplies run short. Other northern species showing up in record numbers included Common Repolls and Pine Siskins. Among the rare birds reported was a Streak-backed Oriole in Loveland, Colorado-¬the state’s first report of this bird, native to Mexico. A December nor’easter deposited a Dovekie in Newton, Massachusetts, the first time this North Atlantic seabird has ever been reported to Project FeederWatch.

Long-term data show some species increasing in number, such as the Lesser Goldfinch in the Southwest. Other populations continue a downward trend, such as the Evening Grosbeak throughout their range. Once one of the most common species seen at feeders in the northern half of the continent, the grosbeaks are declining for unknown reasons.

Beyond the benefits to birds and science, however, is the benefit to participants. "Nature is not merely an amenity; it is critical to healthy human development and functioning," says Nancy Wells, Cornell University assistant professor of design and environmental analysis. Her studies find that a view of nature through the window or access to the environment in any way improves a child’s cognitive functioning and reduces the negative effects of stress on the child’s psychological well-being. Wells also notes that when children spent time with nature early in life it carries over to their adult attitudes and behavior toward the environment.

Project FeederWatch welcomes participants of all ages and skill levels, from scout troops and retirees to classrooms and nature center visitors. To learn more and to sign up, visit www.feederwatch.org or call the Lab toll-free at (800) 843-2473. In return for the $15 fee ($12 for Lab members) participants receive the FeederWatcher’s Handbook, an identification poster of the most common feeder birds in their area, a calendar, complete instructions, and the FeederWatch annual report, Winter Bird Highlights.

Many FeederWatchers echo this comment from Mary Strasser of Wisconsin: "The greatest reward for me as a participant in Project FeederWatch these many years has been observing birds and behavior that I might have missed had I not been part of this project."

2008 Water Year Summary Report

Station Number: MI-BN-3
Station Name: Buchanan 1.4 ESE

Station Location and History: This station is located 1.4 miles ESE of Buchanan, Michigan. Buchanan is located in the southeast portion of Berrien County, Michigan’s southwestern-most county. The rain gauge is located at 4776 Erie Drive (lat. 41.8 N, long. 86.3 W) at an elevation of 759 feet. It is maintained as part of the CoCoRaHS (the Community Collaborative Rain, Hail, & Snow Network). Michigan officially joined the CoCoRaHS Network on July 1, 2008. Therefore, this report covers only the 4th quarter of the 2008 Water Year, July-September 2008.

The Data: Precipitation is recorded at 7:00 AM each morning, in accordance with CoCoRaHS protocol, using a standard 4-inch rain gauge. That measurement represents precipitation that has fallen during the previous 24 hours. Thus, a measurement taken at 7:00 AM on September 15th is an indicator of total precipitation that has fallen between 7:00 AM on September 14th and 7:00 AM on September 15th.

Precipitation Summary: July saw measurable amounts of rain (i.e., ≥ 0.01 inches) fall on 10 (32 percent) of 31 days, with a total accumulation of 2.35 inches (0.08 inches/day).

August produced measurable rainfall on 8 (26 percent) of 31 days, with a total accumulation of 2.33 inches (0.08 inches/day).

September was by far the wettest month of the quarter, with measurable rainfall on 13 (43 percent) of 30 days yielding a total accumulation of 13.00 inches (0.43 inches/day).

For the entire 4th quarter, measurable precipitation, all in the form of rain, fell on 31 (34 percent) of 92 days, producing a whopping 17.68 inches of rain; 74 percent of that total occurred in September, with 53 percent (9.38 inches) falling on just 3 days (September 13-15).

Superlatives:

Longest span of days with measurable rainfall: 7 (September 4-10).

Longest span of days without measurable rainfall: 13 (September 17-29).

Greatest rainfall in 24 hours: 3.83 inches (September 14).

Wettest month: September (13.00 inches)

Comparisons: No comparative data from previous years is available for this site. Therefore, to gauge the relative wetness of this quarter, I offer some comparative data from the nearest locality, South Bend, Indiana (located 12 miles SE of this station). July rainfall for South Bend (2.38 inches) was 36 percent below the norm (1970-2000), August rainfall (1.90 inches) was 52 percent below the norm, and September rainfall (13.96 inches) was 267 percent above the norm. The quarterly total of 18.24 inches at South Bend (which was very close to the 17.68 inches recorded in Buchanan) exceeded the norm at that locality by 59 percent. Thus, the fourth quarter of 2008 can be categorized as abnormally dry in July and August and exceedingly wet (i.e., record-setting) in September.

Temperature, Relative Humidity, and Dew Point: Purely for my own edification, I recorded these statistics on 90 of the 92 days during the quarter. All were recorded at about 7:00 AM, so can be considered to represent lows for each day. Figures for temperature and dew point are in degrees F., relative humidity is in percent. The results follow:

Temperature: High 74 (July 19), Median 60, Low 44 (September 10)

Relative Humidity: High 90 (July 5 & August 9), Median 84, Low 73 (August 22 & September 11)

Dew Point Temperature: High 68 (July 12 & 19), Median 54.5, Low 38 (September 10)

Water Year 2009 Begins

Water Year 2009, as recognized by climatologists and hydrologists, began on October 1st. The fact that it corresponds with the Federal fiscal year is merely a coincidence. The following description of the Water Year by climatologist Nolan Doesken is from the October 1, 2008, edition of The Catch (the bi-weekly newsletter of CoCoRaHS—the Community Collaborative Rain, Hail, & Snow Network):

The water year is the best approximation of the consecutive 12 months that span the "water storage/water usage" hydrological cycle. The water year cycle is particularly obvious in the Rocky Mountains and western U.S. where snow begins to accumulate at high elevations in October and doesn’t melt until the next spring and summer.

Another way to think of the “Water Year” is the resting/replenishing season followed by the growing, harvesting and water-consuming season. As October begins, the summer growing season comes to an end. With the coming of colder weather, evapotranspiration shuts down. In the mountains and the northern states, snows begin to fall. For much of the country and especially the northern states, the months of October through March are months where precipitation from the sky exceeds evaporation from the ground. This means that soil moisture and ground water can recharge. Runoff that reaches the rivers and streams may increase (except in cold areas where the water remains frozen). Then, when next spring comes the temperatures rise again, plants come back to life, snow melts, rivers surge. Then evapotranspiration increases as plants begin to grow. By the summer months, evapotranspiration will once again exceed precipitation for most of the country. This means that soils dry out, river flow may decrease, and little or no water recharges aquifers. Drought becomes especially problematic when precipitation falls short of expectations during the spring and summer months. By next September, crops will be harvested, temperatures will again cool, and yet another water year will come to an end.

The Water Year calendar (October 1-September 30) does not exactly correspond to phenological events in the Midwest, but it’s close enough. As we enter the month of October here in southwestern Michigan, for example, most of the native flowering plants have gone to seed; apples and grapes are being picked; soybeans are being harvested, soon to be followed by corn; tree leaves are turning color and beginning to fall; and the migratory birds are gathering for their southward journeys.

Diagramming Sarah: A Bird Analogy

In an article that examines Sarah Palin’s convoluted speech patterns, grammarian Kitty Burns Florey provides this delightful bird analogy:

The sentences she uttered in interviews with Charles Gibson, Sean Hannity, and Katie Couric seem to twitter all over the place like Mourning Doves frightened at the feeder. Which left me wondering: What can we learn from diagramming them?

If, like me, the very thought of diagramming sentences brings back the most absolutely horrific memories of high school English and you have therefore forgotten everything you ever knew about the topic, a Google search for sentence diagramming will yield many helpful guides, if you have the courage to go there.

Kirtland’s Warbler Population Surges

The 1,791 singing males observed during this year’s census is the highest recorded since monitoring began in 1951, eclipsing the 1,697 singing males recorded in 2007. The lowest number of singing males ever observed was 167, a tally recorded in both 1974 and 1987 (graph).


The 09/28/08 press release from the Michigan Department of Natural Resources follows:

Department of Natural Resources officials today released annual survey information indicating the state's population of the endangered Kirtland's Warbler is the highest number of birds recorded since monitoring began in 1951, with 1,791 singing males observed during this year's census.

The 2008 population exceeds the goal for de-listing that was set in the Kirtland's Warbler Recovery Plan. The number of singing males biologists, researchers and volunteers in Michigan observed 1,791 singing males during the official 2008 survey period, up from 1,697 males observed in 2007. The lowest numbers were recorded in 1974 and 1987, when only 167 singing males were found.

The Kirtland's Warbler survey is conducted each year over a 10-day period during the first two weeks of June, when the birds are establishing their nesting territories. Male warblers are detected by listening for their songs. The songs can be heard at distances up to one-quarter mile, providing an excellent way to detect the birds with minimum disturbance.

The 2008 survey was a joint effort by the DNR, U.S. Forest Service, U.S. Fish and Wildlife Service, Michigan Department of Military Affairs and citizen volunteers. This year, singing males (numbers in parentheses) were found in 12 northern Lower Peninsula counties: Alcona (207), Clare (141), Crawford (288), Grand Traverse (2), Iosco (192), Kalkaska (10), Montmorency (11), Ogemaw (627), Oscoda (209), Otsego (40), Presque Isle (5), and Roscommon (25). Surveyors identified 34 singing males in five Upper Peninsula counties: Chippewa (12), Delta (10), Luce (1), Marquette (6), and Schoolcraft (5). In the U.P., additional effort is made to locate females and several were observed with the males, indicating nesting activity.

For a second consecutive year, singing and mated males were observed outside Michigan. Nine birds were heard in Wisconsin and one male with a female was found in Ontario. Both of these reports are of particular importance as they represent documented breeding of Kirtland’s Warblers outside the known breeding population stronghold.

Although Kirtland's Warblers have begun to expand into new areas, the core of the population remains dependent on northern Michigan's jack pine barrens ecosystem for nesting habitat. The warblers nest on the ground and typically select nesting sites in stands of jack pine between four and 20 years old. Historically, these stands of young jack pine were created by natural wildfires that frequently swept through northern Michigan. Modern fire suppression programs altered this natural process, reducing Kirtland's Warbler habitat. The result was that the population of Kirtland's Warblers declined to the point that they were listed as endangered.

To mimic the effects of wildfire and ensure the future of this species, the DNR and its partners at the state and federal level manage the forests through a combination of clearcutting, burning, seeding and replanting to promote warbler habitat. Approximately 3,000 acres of jack pine trees are planted or seeded annually on state and federal lands, primarily for the purpose of providing habitat for Kirtland's Warblers.

"New habitats are continually developed to replace those that become too old for Kirtland's Warbler nesting," said acting DNR Endangered Species Coordinator Sherry MacKinnon. "Through continuing management, we expect there to be sufficient habitat to support the warbler population through the foreseeable future."

Elaine Carlson, DNR wildlife biologist, emphasized how the habitat management program has produced benefits that extend well beyond the recovery of a single species.

"In addition to generating habitat for the Kirtland's Warbler, the jack pine management program provides valuable forest products as well as habitat for a variety of plants, songbirds, game animals and other wildlife," Carlson said.

Strange New World—The Ocean

Joel Achenbach writes about the grand opening of the Smithsonian Institution’s Ocean Hall. An excerpt:

The ocean’s deepest point is about seven miles down. The hall’s project manager, Elizabeth Musteen, says only ten human beings have ever been deeper than 3 1/2 miles below the surface—which means that the ocean trenches have been explored by fewer people than have explored the moon.
