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.
