More and more Common Yellowthroats

Captain Sam's

It was another busy day out at Captain Sam's with 130 new birds and 11 recaptures of 20 different species. Common Yellowthroats made up most of the captures again with 95. This makes 645 Common Yellowthroats banded in the last 10 days at Captain Sam's alone! At this rate, it could be a record breaking year for this species at KIBS. The highlight of the day was a first-of-the season Common Ground-Dove for Captain Sam's. It seems they have declined at Captain Sam's over the years, but there is still a pretty good population out at Little Bear where they have already caught a few.

Over the past few days, we have also noticed the movement of resident species as they disperse from where they spent the breeding season on Kiawah. We are catching a few more new Downy Woodpeckers, Brown Thrashers, and Northern Cardinals along with old Northern Cardinal recaptures returning to the spit. Below is a picture comparing a hatch-year Brown Thrasher and an after hatch-year we caught earlier in the week. Young Brown Thrashers have a yellowish-gray eye whereas the adults usually have a yellowish-orange eye.

Little Bear

Blustery northeast winds blew in a decent number of birds today, with 77 new and 11 recaptured, for 88 total captures of 18 species. 50 new Common Yellowthroats again made up the majority of captures. Some interesting birds included a Baltimore Oriole, a Yellow-breasted Chat, a Tufted Titmouse, a handful of House Wrens, and two Black-and-white Warblers. Like Captain Sam's, we have been catching some new unbanded individuals of resident species in the last few days, like Brown Thrashers and Northern Cardinals.
