Saturday's Results

There was a definite increase in migrant activity this morning probably due to the advancing cold front scheduled to arrive in the morning .  We banded 31 new birds and had 2 recaptures of 12 different species.  We had a very good mix of  neotropical warblers including American Redstart, Prairie Warbler, Black-and-White Warbler, Yellow Warbler, Northern Waterthrush, Common Yellowthroat, Worm-eating Warbler, and Wilson's Warbler.  

Wilson's Warbler (hatch-year, female)



Worm-eating Warbler (after hatch-year, sex unknown)

We also banded our second Acadian Flycather of the season this morning.  These can be difficult to separate from "Traill's" Flycatcher by plumage alone, therefore a number of measurements are taken.  One of the first things we look at when we get an Acadian/"Traill's" is the color of the legs.  Grayish legs indicate Acadian while blackish legs point toward "Traill's".  However, leg color alone is not enough for most individuals and other measurements such as bill length and width are needed. 



Acadian Flycatcher:  note the gray-colored legs
