Rio Grande Valley State Park

Location: Rio Grande Valley State Park
Observation date: 8/23/09
Notes: These WCSP were of the Inter-mountain west sub-species with the dark lores.
The Warbler "Vermivora" Nashville was feeding low in green grasses.
I was sure it was Nashville. But once in the nature center on the sighting posting borad a MacGillivray's warbler had been posted, so I X both birds.
