CAPTAIN SAMS
Captain Sams had a significantly improved day of banding compared to yesterday, with a total of 34 new birds and 20 recaptures. It was a welcomed pace, as we are still catching a good variety of birds, and it's nice to have the time to mull over some interesting molts! Today we caught a few late migrants such as a recap Black-throated Blue Warbler who has been around at least since yesterday, stocking up on resources before she continues South, and a newly caught Ovenbird whom we speculate could be another individual planning to spend the winter here (time will tell!).
We also banded two House Finches, which the station has now only caught 13 of this year! This individual had undergone an eccentric molt, which is what helped us determine the age as a hatch-year. The inner secondaries (tertials) and outer primary feathers (highlighted in green) are freshly molted, replaced feathers. Those highlighted in red are worn, retained feathers that won't be replaced until next summer/fall. This molt limit is admittedly a tougher one to see in photos, but a darker brown is observed in the replaced feathers, in addition to a darker rachis (the center shaft of the feather). There is also more wear on the tips of the older retained feathers.

LITTLE BEAR
Today was a bit of a slow day with a total of 32 birds (22 new and 10 recaptures). We caught the usual late-season characters, including Yellow-rumped Warblers, Swamp Sparrows, and a recaptured Ruby-crowned Kinglet.
The rain yesterday morning created a few wet spots, but I was happy to see that these are already being reduced down to small puddles. Hopefully Little Bear can stay dry for this last week of banding!
