Subject: [birders] Barred owls
From: Ann Zinn <annczinn(AT)umich.edu>
Date: 18 Apr 2008 7:31am
We had a Barred Owl party in our yard last night! There were at least
two of them,
and they were calling in ways I have never heard before. At one point
it sounded as if they were fighting. There were squacks and caws as
well as the usual "who cooks for you" call. Those of you who know owls
perhaps can explain this. It went on for about 10 minutes before they
flew farther away and the calls sounded more normal.
My questions are:
--I thought owls mated in February, but could this have been mating
behavior?
--Could these have been young ones or is it too early for them to be
flying around?
--Was it a territorial battle?
It was very noisy, and probably scary for people who didn't recognize
the calls in the dark.
A. :-)

Got up late for work this morning and was pleasantly surprised to see 5
fox sparrows poking around the flower bed just off my front deck. Also
an eastern towhee. Weren't more than 15 feet from the window.

Subject: [birders] Lecture Mon., Apr 21 MILKWEEDS: INSECTS, TOXINS
From: Larry Nooden <ldnum(AT)umich.edu>
Date: 18 Apr 2008 11:56am
MONDAY, 7:45 P.M. THE NATURAL AND UN-NATURAL HISTORY OF MILKWEEDS:
INSECTS, TOXINS, AND OTHER STORIES presented by MARK D. HUNTER, Professor,
University of Michigan EEB & SNRE. Free and open to the public. Michigan
Botanical Club - Huron Valley Chapter at the at the Matthaei Botanical
Gardens auditorium, 1800 N. Dixboro Rd. Ann Arbor, MI. This will be a
joint meeting with the Wild Ones, an organization concerned with native
plant culture.
Here's a glimpse of an almost invisible, but very important part of the web
of life, the chemical mediation of plant-animal interactions. The
milkweeds with their toxins, cardenolides, illustrate this phenomneon very
well, and they certainly influence bird feeding patterns.
Milkweeds in the genus Asclepias are well-known as the host-plants of
monarch butterflies. Monarch caterpillars can appropriate toxic chemicals
(cardenolides) made by milkweeds to protect themselves against certain
predators. But the story of milkweeds and their associated insects is much
more complicated than it first appears. A wide range of insects, including
aphids, beetles, ants, and flies are dependent upon milkweed plants.
Moreover, there are many different milkweed species that vary in their
chemistry and not all of them produce the toxins upon which monarch’s rely
for defense. Why do milkweeds vary so much in chemistry? What are the
effects of this variation on insects? These questions are difficult to
answer, but a few glimpses into the world of milkweeds will show that some
of our favorite stories about them may be incomplete. Even monarchs may be
relying on milkweeds for their antimicrobial properties rather than their
effects on predatory vertebrates. Milkweeds still have much to teach us
about the natural history, ecology, and evolution of communities in
Michigan.
Mark Hunter is Professor of Natural Resources & Environment and Professor
of Ecology and Evolutionary Biology at the University of Michigan. He
received his bachelors degree in 1984 and his doctorate in 1988, both from
the University of Oxford in England. After serving as a NATO International
Fellow and an NSERC International Fellow, he joined the faculty of the
University of Georgia in 1995. While at UGA, he served as Professor in the
Institute of Ecology and as founding Director of the Center for
Biodiversity and Ecosystem Processes. He joined the University of Michigan
in January 2006 as Professor in both the Department of Ecology and
Evolutionary Biology and in the School of Natural Resources and
Environment. His research interests include plant-herbivore interactions,
population dynamics, ecosystem ecology, and biodiversity. This research
links population processes and ecosystem processes in terrestrial
environments. Dr. Hunter has published over 95 journal articles and books
and served on the editorial board of several major journals. Media coverage
of his research includes The BBC, CNN, The National Geographic and National
Public Radio/PRI.

Subject: [Ohio-birds] Magee area migrants April 17-18
To: OHIO-BIRDS(AT)LISTSERV.MUOHIO.EDU
[ Double-click this line for list subscription options ]
Along the Lake Erie shoreline in northwest Ohio, and specifically in the
area of Magee Marsh, Ottawa-Lucas Counties: The last several days have
featured warm temperatures, and winds with a strong southerly component.
A lot of migrant birds have been riding that train north into our area,
with large numbers of arrivals each of the last three days. At least 14
species of warblers were reliably reported from the Magee Marsh boardwalk
on April 17 - 18. The most surprising was a very early Am. Redstart;
others were all species expected in the early part of the migration,
including multiple singing N. Parulas, Black-throated Greens, Pines, and
Nashvilles, and scores of Yellow-rumped (Myrtle) Warblers. "Overshooting"
southern warblers were represented by Hooded and Prothonotary (although
the latter could have been a local breeder) and a Louisiana Waterthrush,
found in the same area as a Northern Waterthrush near the west end of the
boardwalk. Other migrants present at Magee on 4/18 included very large
numbers of Hermit Thrushes, one Blue-headed Vireo, two House Wrens, at
least 10 Winter Wrens, and at least 20 Rusty Blackbirds. On 4/17 I saw a
male Yellow-headed Blackbird with a mixed blackbird flock in a corn
stubble field on Krause Road west of Ottawa National Wildlife Refuge.
The
auto tour route at Ottawa is scheduled to be open this Saturday, April
19,
from 9 a.m. to 4:30 p.m., so we'll get a chance to see if the
Yellow-headeds are back on territory there.
The forecast calls for cooler temperatures this weekend and a good chance
of rain, but the southerly wind flow looks likely to continue for a few
more days. There is turnover every day now, so the individuals present
will probably change, but I expect the diversity to continue to be good
(for this early in the season) throughout the weekend in all the migrant
traps along the lakeshore here.
Since there is so much interest (throughout Ohio and beyond) in the
migration through the Crane Creek - Magee area of northwest Ohio, we've
put together some pages of birding information that will be updated
regularly with reports and predictions throughout the spring. These
pages
are accessible through the Black Swamp Bird Observatory website at
http://www.bsbobird.org/birding/
Hope to see you out in the field --

I saw my 1st Green Heron for the year at Dolph this AM.
On US23 Northbound, I had a single Broad-Winged Hawk circling overhead....
another first for the year. There may have been more, but all I saw was
the one.

Subject: [birders] Barred owl party
From: Ann Zinn <annczinn(AT)umich.edu>
Date: 18 Apr 2008 8:51pm
Woops, sorry folks. I forgot to put in my location. Our home is in
the SE corner of Livingston County, about two miles north of Whitmore
Lake, off Marshall Rd. between Nine Mile and Silver Lake Rd.
Behind our house there is an undeveloped stretch of woodland that
borders the SE branch of the Huron River and runs between Sandy Bottom
Lake and the bridge on Marshall Rd. We have often heard owls in the
woods and in our yard, though this year not as much. It was a joy to
hear the barred owls.

Those of you heading to Ohio tomorrow .... I birded all day today
(Friday) around Magee Marsh, Metzger marsh and Ottawa NWR. I had a 56
bird day and there were some that escaped me. By far the best place to
go is Magee. =20
=20
The causeway produced a peregrine falcon at 8am right by the bridge and
a Palm Warbler and Common Snipe near the pull-off just past the bridge.
The rest of the drive across the causeway produced horned grebe in
breeding plumage, the usual spattering of ducks, swans, Coots and a
Northern Harrier. Lots of Blue-winged Teal.
=20
The boardwalk has the birds and the people! At the viewing tower there
was a Black and White and a Prothonatory Warbler. The rest of the walk
has lots of Hermits, Yellow-rumped everywhere, Kinglets, Wood Ducks and
lots of White-throated Sparrows.
=20
Someone said that Ken Kaufman was on the boardwalk (bearded guy with an
exquisite camera). Maybe some of his karma will still reside in the
morning for you.
=20
By 4pm the boardwalk was very quiet - get there early for best results.
=20
Ottawa was dead by comparison - two eagles on their nest were fun to
watch.
=20
Have a good time!
