Today was an enjoyable day at the banding station. Nice birds and good people to share the birds with. Twenty bird species captured with two new species for the year: Northern Waterthrush and Black-and-White Warbler. We recaptured the Chestnut-sided Warbler we banded yesterday. It gained 10% of its body weight in one day. The Yellow-breasted Chat we recaptured today gained 20% from when we banded it a week ago. The Ovenbird also banded a week ago also increased its weight. Veery recaptured also gained weight from its original banding date a week ago. So... unless we had radio tags on those birds we do not know if they ventured south or north or where they had been between today and the last banding date. Capturing them does help us determine if they are using this patch of olives and that they have increased weight since the last time we captured them. So many questions that can be answered with the utilization of different research tools with banding, radio transmitters, or observations.
