Captain Sam's
Today was a much more productive day out at Captain Sam's! Largeish flocks of Yellow-rumped Warblers are beginning to come in and invade the wax myrtles. The large majority of our captures today were Yellow-rumped warblers and recapture Catbirds that were banded this season. A few straggling Redstarts, Parulas, and Black-throated Blue Warblers are also hanging around.
Now for the fun stuff!!!
In the spirit of halloween we decided to compile some slow motion videos we have taken this season of our best Monster (sounding) Birds! Make sure your sound is turned up! You're going to want to hear this!!!
Who knew such small adorable creatures could sound so scary and so funny all at the same time!! We hope you all have a happy Halloween and enjoyed this post!

Little Bear
We also had a nice busy day at Little Bear, with some more Yellow-rumped Warblers in the area, though Gray Catbirds were still our dominant species. We had 65 new birds and 19 recaptures of 22 species.
Yellow-rumped Warblers are fairly easy to age and sex because they have such variation in plumage. Once we've aged the bird (usually with an easy-to-see alula molt limit), we can look at overall coloration as well as the patterns/colors of a few specific areas to determine sex. Pictured below are the two ends of the spectrum, a dull hatch-year female and a more boldly colored after hatch-year male.
