Today I decided to make a try for the Cassin's Vireo at Resaca de la Palma State Park near Brownsville. Even though I still need that species for my Cameron County list, I have not made much effort during my past few visits. It's always a chore trying to distinguish between Cassin's Vireo and pale Blue-headed Vireo. In west Texas during migration I feel pretty good about calling Cassin's Vireo but down here I've seen way too many pale Blue-headed Vireos to feel comfortable about making the call. I wish they would just lump 'em all back into Solitary Vireo. Anyway the only "Solitary" Vireo I saw today was a dark headed Blue-headed so I didn't have to worry.
Meanwhile, the Roadside Hawk has been present since November.
