Monday's Results - "The Return of the Yellowthroats"

We had a great day of banding with 143 new birds and 2 recaptures of 13 species.  Species diversity was not what I was hoping for as Common Yellowthroats made up over 70% of the banded birds but we did have two female Cape May Warblers (1 adult and 1 juvenile) and a nice array of other warblers.  Gray Catbirds numbers appear to be increasing a little bit everyday and I bet the next big cold front will bring in a bunch of them.

Another interesting highlight of the day was a Sora that was flushed from the grasses as we were checking the nets.

The latin name for the Cape May Warbler is Setophaga tigrina.  Tigrina translates to "striped like a tiger" which is a very good description for this species which can be very difficult to identify in the fall.  If you see a confusing-looking warbler in the fall that is heavily streaked across the breast with a greenish-yellow rump patch, it probably is a Cape May Warbler.

I would like to thank the banding assistants and the volunteers for all of their hard work!  Pat, Dave, and Keith you did a great job scribing data!
