After yesterdays complete wash out, I headed down to the park with another full group of visitors. It turned out to be the best day of the spring migration by far. We tallied 25 species of warblers, all 6 regular vireos, both cuckoos, a perched LEAST BITTERN, and many other great birds. The number of BLACKBURNIAN WARBLERS was particularly impressive. I estimated that we spotted between 150 and 250 of these gorgeous songbirds. We also had huge numbers of NASHVILLE and BLACK-THROATED GREEN WARBLERS as well.
