Campbell Flats was hopping this morning, with the most pronounced "fall out" of warblers and other songbirds that I've witnessed yet this season. The treetops -- especially white birches -- were full of foraging warblers, many of which were challenging to identify in the flat light. Various people were there, and no doubt we all ended up with different lists. Activity was fast and furious from ~7:45-8:30 am, and I'd guess I successfully identified fewer than 50% of the birds I saw.
