Blackpoll warblers (Setophaga striata) are generally the last warblers to show up in Central Park during spring migration. Seeing them is a little bittersweet, for we know the migration has pretty much completed for the season.
These blackpolls were seen September 27, 2021, at Green-Wood Cemetery and October 9, 2021, at the 9/11 Memorial at the World Trade Center.
