Saturday's Results

I was feeling a bit under the weather after banding yesterday and wasn't able to do my normal write-up.  So here it is a day late . . .


As expected, we had a rather slow morning with 17 new birds and 2 recaptures of 11 different species.  "Big" birds were well represented today with a Veery, Swainson's Thrush, Gray Catbird, 3 Northern Mockingbirds, and an Eastern Towhee. 

Eastern Towhee (after hatch-year, male)

These two Northern Mockingbirds were caught together in the same net.  The bird on the left is an adult while the bird on the right is a juvenile.  Two obvious characteristics stood out when we were determining their age.  The first is eye color; note the bright yellow eye on the adult compared to the dull yellow eye in the juvenile.  The other thing we noticed was that the juvenile had spotting on the upper breast and the adult had a clean white breast.
