As well as I did with sparrows this spring I did probably as badly with warblers. We had far fewer passerine migrants at Tiscornia than last year and I didn't really run into may low birds either at Floral or at my house. In fact I never saw a Golden-winged or a Black-throated Blue though I did hear one of each.
Blackburnian Warbler was probably the only one which I saw (and especially heard) in above average numbers this spring. This one is from Riverview Park
It feels like there's more Hooded Warblers on territory at Floral this year than last, though that may just be my memory
