October 25, the Yellow-rumped Warblers Arrive

Today we had 110 new birds, and 13 recaptures for a total of 123 birds spanning 11 species. Only 10% (11 birds) of our new birds today were Gray Catbirds, compared to 53% one week ago, on Saturday, October 18th. As the number of new Catbirds dwindles, a new species has arrived to replace them. The 75 Yellow-rumped warblers we captured constituted 68% of our new birds today. This is a sign of things to come, as we expect the number of yellow-rumped warblers to keep increasing as we band into November. We banded 1054 yellow-rumps in the fall of 2013, and 1060 in 2012, so it is reasonable to expect that these birds are likely to keep us busy for the next several weeks.
