Captain Sam’s:
The morning started with a rush of new birds brought in on the western prevailing winds last night. Our first run of the day had 21 new captures and 2 recaptures. By the days end we processed a total 93 birds. Warbler diversity was excellent: 11 species. The species we captured most was the Common Yellowthroat with a total of 29 new individuals; our previous high count for this species was 6 on Sep 1, and our season total before today was 13 new birds. This influx indicates that migration is steadily making it’s annual south bound push.

Little Bear:
As we prepared our coffee this morning and checked the radars, we saw that we were headed out for our first busy morning. Josh and I took off after we were all fueled up and popped open the nets ASAP. Our first run yielded us 21 birds. As the morning progressed, numbers started dropping run by run until late morning where things took a turn and we brought in about ten more birds on one of our last net runs. When it was all said and done, we had banded 76 new individuals for the day. We surprisingly didn’t even process a single recapture today. We of course pulled in a couple first of the seasons for Little Bear, which included an Ovenbird and a Veery. Both are expected species, but we definitely thought we would have already had an Ovenbird by now. Notably, we caught two more Worm-eating Warblers and another Yellow-throated Warbler! Both of these species were ones I had never seen in hand before so that was a real treat.

While aging a good ole Common Yellowthroat today, I made an uncertain observation about the usual feathers we take note of. I was looking at the alulas trying to find the typical molt limit on a Hatch-year warbler between the A1 and A2 feather when I noticed that this individual had what looked like two A2’s! This is something that none of us here at KIBS has ever seen before. Like Captain Sam’s post, this appears to be a genetic abnormality. A very fascinating one at that.
