In Maryland/Pennsylvania/Virginia the song is chip-chip-chip-chee-bomp, abruptly ending, the first three notes short, deliberate, evenly spaced, and chip-sounding, the chee slightly higher than the first three but still short, the bomp slightly lower.
I once, while in high school, picked up a dazed hooded warbler that had struck a glass window, held it as it recovered, and watched it fly away looking OK.
I don't have time to see this bird, but hope many do. I would also like to in person hear that song. I've seen them in south Texas in spring migration, but don't recall any song.
