Bay-breasted Warbler: no contrasting collar on nape, no chestnut color observed anywhere, white underside created greater contrast above/below than expected for Bay-breasted, orange feet instead of dark. Pine Warbler: streaking on back, orange feet instead of dark, long UnTC/short tail. Cape May Warbler: brighter white wing bars, whiter/lighter belly and throat, no significant streaking on throat. Blackburnian Warbler: no orange wash observed anywhere, no triangular face patch, finer supercilium. Yellow-rumped (Myrtle) Warbler: some yellow in throat, visible eyeline, relatively short tail without strong black border. Palm Warbler: finer supercilium, relatively short tail, no brown/rufous cap, white UnTC.
