Tonight the numbers were higher for the Chimney Swifts at 944 Fifth Avenue. About 370 went to roost in about four minutes with them assembling about 8 minutes before hand. This is much quicker than last week.
I’m not sure how to reconcile the numbers with last nights count in the rain. Did swifts leave in the northerly winds, to be replaced with more migrants this evening? I have no idea. But I’m glad that we’re still seeing good numbers of swifts roosting on 5th Avenue.
