Notes:
This
week was all about census and our annual spring clean-up. A small group
of dedicated volunteers worked their tails off for two days to get the
site ready for spring banding. New boardwalks were built, a new release
platform was put together, the cabin was cleaned out, the nest boxes
were cleaned out, the nets were set up, and almost 15 tons of gravel
were spread out in especially muddy areas around the site. We
would
like to extend a large thank you to our assistants for working to
tirelessly and enthusiastically to ensure that this work was completed
well before banding was scheduled to begin.
The highlight of the
week in terms of birds was the discovery of a pair of Ring-necked Ducks
on Stoneycroft Pond - our first new addition to the MBO checklist this
year, and the 181st species on it overall. Stoneycroft Pond
actually provides some suitable breeding habitat for Ring-necked Duck,
including shallow water and emergent vegetation. The pair was seen
again on a couple of other censuses later in the week, so at least in
the short term it seems they are hanging around.
Despite
some pretty terrible weather early in the week, this week’s censuses
netted us 8 other new species for this season, and 6 new species for 2007:
Turkey Vulture, Brown Creeper, American Wigeon, Great Blue Heron,
Red-tailed Hawk, Yellow-bellied Sapsucker, Yellow-shafted Flicker, and
Cooper’s Hawk.
This
week’s top ten is quite similar to last week’s, with a slight shuffle
after the top five. The number of Canada Geese has dropped
substantially, however, most being spotted going to and from the fields
east of MBO.
