Monday October 16, 2017: 281 new birds of 14 species, 28 recaps. Bird of the day was Ruby-crowned Kinglet with 156 new bands.
Yes . . . you read that right. 156. Our busiest day so far this fall (until today) saw 153 new birds banded, and this morning the RCKIs topped that number. Last fall we banded 327 RCKI, and the highest total (48) came on October 10. We can’t really draw population-level demographic conclusions based on these numbers – they are surely attributable to the passage of a cold front followed by NW winds overnight which succeeded many days of SW winds. The birds must have been waiting for their chance, and last night (after our microburst passed through) they took advantage of it.
Our distant second-place bird today was Golden-crowned Kinglet, with 52 new bands. Not nearly as impressive as the RCKI numbers, but note that they still outdid 90% of our daily banding totals so far this fall.
