Spring migration - Princeton - May 2nd

Overnight rain combined with a southerly wind raised the prospects of migrant dropouts, and before I even got into Princeton there'd already been mention of them in a couple of places in NJ. The road towards the water facility at the Institute Woods had a couple of trees with many warblers in them - most of them Yellow-rumped Warblers. Quite a few singing species including multiple Black-throated Green Warblers and Blue-winged Warblers. I heard and tracked down a Blackburnian Warbler, which together with Black-throated Blue Warbler were new birds for the year. Overall, however, diversity wasn't that high although I did make it to 10 warbler species in about 1/4 of the time it took me the previous day.

Twenty minutes later, by 10am, these same trees were empty and the flock had moved on.
