[mou] Re: Hawk Ridge warbler migration

[dgrosshu@nrri.umn.edu]

A substantial movement of birds occurred at Hawk Ridge on August 22, with 241 
birds banded.  This is the first significant migration of birds since 
operations started on August 4th.  Sixteen warbler species comprised the bulk 
of birds banded, with highlights being a Connecticut and 2 Bay-breasted 
warblers.  Additionally, the first Brown creeper and second Slate-colored junco 
added to the early season diversity.

Red crossbills continue to be observed nearly every day.  The vast majority of 
birds appear to be moving south, although, an occasional flock has been 
observed heading north.  Many of these flocks have ranged from 15 to 30 birds, 
with a couple 40+ flocks.
