Subject: [birders] Common Moorhen, Trinkle Marsh, 4/24 AM
From: "Dan Sparks-Jackson" <sparksjackson(AT)aol.com>
Date: 24 Apr 2008 9:16am
I was more than a little surprised to see a Common Moorhen at Trinkle
Marsh on this morning's commute. This spring arrival date beats my old
records by ten days. The bird was also in that peculiar
'oblivious-rail-mode', happily gleaning food off of the emerging pond
lilies about twenty feet from my running car. The comical impression this
species always leaves me with was further enhanced by close-up views of
the red 'tube-sock-stripe' markings at the top of its pale green legs.
Always strikes me as a bird designed by committee.
Spring seems to be arriving early and often.

Birders,
Bruce Bowman called at 10am to say that the Eared Grebe is still at LEMP as
of today. Follow the directions below, and look for two islands in the lake.
The bird was about 3/4 of the way out towards the right most island. For part
of the time Bruce observed the bird, it was not diving, allowing good views.

Good evening,
Daryl Aspery, Scott Jennex and I saw Walt's Eared Grebe at Lake Erie Metropark
tonight. We left at 6:30 after 15-20 minutes of viewing.
From the boat launch, walk south on the Cherry Island Marsh Trail (the segment
next to the lake) and head to the big bridge. The bird was east of the bridge
(lake side) and diving frequently. It would spend literally a few seconds on
the surface before diving again. It would also come up quite a distance away
from where it dove. In short, a quick glance will not work. You must be patient
and look. Viewing distance was hard to estimate, but it was in the order of
hundreds of yards a times. Remember, from the bridge, you are up off of the
water. This certainy helped us keep track of the bird. The breeze made the
water a bit choppy.
Good luck.

Subject: [birders] Peregrines at Burton Tower
From: mlparow(AT)umich.edu
Date: 24 Apr 2008 11:12am
I haven't seen the Peregrines at the Burton Bell Tower much since they were
doing some repair work on it, but both were present today. The female was
sitting on the NW corner of the tower. I watched as the male did a big
loop, they called to each other, and then the male landed on the female for
a brief time, made another loop and then landed on the NE corner of the
tower. I'm assuming this was mating behavior, but I observed all of this
from the front steps of the Rackham Bldg. This happened just after 11am
today. --mike

Subject: [birders] Turkey at bird feeder
From: Larry Nooden <ldnum(AT)umich.edu>
Date: 24 Apr 2008 11:28am
Since there has been a lot of interest in the resurgence of turkeys in SE
Michigan, I think it is of interest that they are appearing at my bird
feeder in a semirural area west of Ann Arbor. They are feeding on the
ground under the feeder, and I expect they feed on seedlings and maybe
insects as well as the seeds. I suppose that if they could they would also
grab the small sparrows also feeding there.
It is worth noting that without natural controls turkey populations can
exceed the carrying capacity of a natural area, and then, they can have
some very significant ecological impacts, e.g. suppression of forest
regeneration due to consumption of seeds and seedlings.

Subject: [birders] 3 peregrine day
From: "Richard Neubig" <rneubig(AT)med.umich.edu>
Date: 24 Apr 2008 12:13pm
Hi all,
Yesterday (Weds 4/23), I was lucky enough to see peregrines three times around
the UM campus.
At about 11;45 leaving the Chemistry building, an adult bird slowly glided from
over the dental school building toward and over the chemistry building. I then
watched it circle over main campus a bit. On its first pass over me, I could
easily make out the mustache by naked eye.
Just 10 or so minutes later, another one was soaring over the medical campus
near Taubman Library. It was on a thermal and soared up nearly to being out of
sight.
Then on my way home about 5:30, I saw a flurry of activity over the huron river
(at Maiden Lane) and there was a third peregine harassing 3 turkey vultures. It
then broke off and flew up over the MSRB complex where I lost sight of it.
Fun!

Subject: [birders] Eared Grebe photos / Re: Eared Grebe still at
LEMP, Thursday, 4/24, 10am
From: "Bruce M. Bowman" <bbowman99(AT)comcast.net>
Date: 24 Apr 2008 3:05pm
To find the Eared Grebe--where it was this morning, at least--walk south
along the lake on the trail from the parking lot until you get to the
second boardwalk section. This is "the big bridge." (See Paul Cypher's
post below.) There's some water on the right side and the lake on the
left side. Yesterday evening the bird was straight out from the big
bridge. This morning it was visible from there, but it was quite a
distance farther south. Look at about a 30-degree angle from the
shoreline. I watched it from 9:15 to 9:30. After getting some 60X
digiscope photos from the big bridge, I walked a short distance beyond
the big bridge to where there's a yellow barrel to the left of the trail.
I watched from there for awhile and then continued a distance along the
trail until, where it curves right, there's a path to the left that leads
to a bench at the edge of the lake. This was the best place for viewing
the bird. From a pixel count from my photos I determined the distance to
the bird to be about 960 feet. You can probably ID it with binoculars,
but a scope will be a big help, of course. From this location I was
looking toward the right edge of the second island clockwise from
straight out. This is at about a 35- to 40-degree angle from the
shoreline. See the islands in my last photo at the photo sharing site.
The bird was toward the left edge of the channel that's to the right of
the second island.
The bird was not diving from 9:15 to 9:30, so I took a lot of photos.
When it started diving at 9:30, I quit. I've put the best (poor) of my
photos of the Eared Grebe at the photo sharing site:
http://www.umich.edu/~bbowman/birds/se_mich/photos.html
This grebe appears to be in full breeding plumage.

I joined the Washtenaw Audubon Society walk in the Arb this morning. I =

At the western end of Dow Field the group informally split in two.

phoebe, chickadee, goldfinch, crow, downy woodpecker, red-bellied =
woodpecker, white-breasted nuthatch, cowbird, common grackle, red-winged =
blackbird, robin, and probably others I have missed), some migrants =
(small flocks of blue jays), and -- of special interest to the group -- =
a pair of wood ducks in the trees just downstream of the beach. Sadly, =
our section of the group saw no warblers, although I had seen =
yellow-rumped warblers in Furstenberg on Wednesday. Perhaps it is =
between waves of migration. Or our luck was just not good today.
We did find an interesting black-bristled caterpillar in Heathdale. =

noticeable on the body of the fairly large, curled-up specimen. None of =
us could identify it. Checking when I got home first with the compact =
Peterson First Guide on Caterpillars, I found that it is the larva stage =
of the giant leopard moth. We also saw several butterflies -- mourning =
cloaks, spring azures, and cabbage whites -- in Heathdale. Mayapples =

Heathdale, and we saw a yellow trout lily, several bloodroot blossoms, =
and spring beauties as we went.

Subject: [birders] article: "Tests Confirm T. Rex Kinship With Birds"
From: Maryse Brouwers <mab(AT)ams.org>
Date: 24 Apr 2008 3:42pm
From today's NY Times:
Tests Confirm T. Rex Kinship With Birds
By JOHN NOBLE WILFORD
In the first analysis of proteins extracted from dinosaur bones, scientists say
they have established more firmly than ever that the closest living relatives
of the mighty predator Tyrannosaurus rex are modern birds.
The research, being published Friday in the journal Science, yielded the first
molecular data confirming the widely held hypothesis of a close dinosaur-bird
ancestry, the American scientific team reported. The link was previously
suggested by anatomical similarities.
In fact, the scientists said, T. rex shared more of its genetic makeup with
ostriches and chickens than with living reptiles, like alligators. On this
basis, the research team has redrawn the family tree of major vertebrate
groups, assigning the dinosaur a new place in evolutionary relationships.
Similar molecular tests on tissues from the extinct mastodon confirmed its
close genetic link to the elephant, as had been suspected from skeletal
affinities.
Our results at the genetic level basically agree with what has been seen in
skeletal data, John M. Asara of Harvard said in a telephone interview. There is
more than a 90 percent probability that the grouping of T. rex with living
birds is real.
Dr. Asara and Lewis C. Cantley, both of Beth Israel Deaconess Medical Center
and Harvard Medical School, processed the proteins from tissue recovered deep
in bones of a 68 million-year-old T. rex excavated in 2003 by John R. Horner of
Montana State University. Mary H. Schweitzer of North Carolina State University
discovered the preserved soft tissues in the bones.
For the molecular study, Dr. Asara and Chris L. Organ, a researcher in
evolutionary biology at Harvard, compared the dinosaur protein with similar
protein from several dozen species of modern birds, reptiles and other animals.
Dr. Organ was the lead author of the journal report, which concluded that the
molecular tests confirmed the prediction that extinct dinosaurs would show a
higher degree of similarity with birds than with other extant vertebrates. The
researchers said they planned to extend their investigations to include
comparisons of T. rex protein with more species of birds, reptiles and other
dinosaurs.
Dinosaur paleontologists were not surprised by the findings. An accumulation of
fossil evidence in recent years had given them increasing confidence in their
contention that birds descended from certain dinosaurs or as they sometimes
put it, birds are living dinosaurs.
The new research, Dr. Organs team wrote, suggests that molecular data from
long-extinct organisms may have the potential for resolving relationships at
critical areas of the vertebrate evolutionary tree that have, so far, been
intractable.

I joined the Washtenaw Audubon Society walk in the=20
Arb this morning. ...=20
We did find an interesting black-bristled=20
caterpillar in Heathdale. Between the bands of bristles, narrow dull red=20
bands were quite noticeable on the body of the fairly large, curled-up=20
specimen. None of us could identify it. Checking when I got home=20
first with the compact Peterson First Guide on Caterpillars, I found=20
that it is the larva stage of the giant leopard moth. =20

Two Soras on our marsh calling intermittently today as well as a Mocking=
bird calling frequently. I was able to ID them both visually as well. =
The Mockingbird is a LIFER for me and what a treat to hear it call so m=
any different bird calls......amazingly accurate imitations. The first c=

Subject: [birders] Eastern Kingbird, Gallup Park, 4/24/08
From: Jacco Gelderloos <jjgelderloos(AT)yahoo.com>

Folks,
During an evening stroll with the family I was shocked to first hear, then see
an Eastern Kingbird over the river at Gallup Park. Just checked "Birds of
Washtenaw County" and this would qualify as a record early arrival date for the
species. Spring certainly seems to be here!
Good birding,
Jacco

Earlier this week I was lucky enought to grab some nice flight shots of
Forster's Terns and Common Terns at Pt. Moo. I've posted a couple composite
images on my blog with
a review of field marks that can be used to tell them apart. Take a look!

Subject: [birders] birding around Detroit
Hi fellow birders,
I am an amateur birder based in Bangalore, India. I will be visiting the Detroit
area on business for 2 weeks in May (weeks of May 5th and 12th) and am looking
for suggestions on birding spots in the vicinity. I will be staying at a hotel
in Warren, and will have access to a vehicle. On weekdays I would like to do
some birding in the early morning/evening at a nearby location. I will have the
weekend on May 10-11th for longer (half day/full day) birding trips at a
reasonable driving distance.
If possible do mail me back with suggestions on how to maximize my birding
experience there, given that I have limited time. If you are free on any of the
days, then it would be great to have company for birding as well. I have not
done much birding in North America before...
Look forward to hearing from you.
Thanks and best regards,
Garima
