A largish, slow-moving warbler that inhabits thick vegetation from marshes to pine woodlands with dense thatch-palm undergrowth. Rather similar to Common Yellowthroat, but larger and more robust with a proportionately heavier bill. Males are entirely yellow below unlike Common Yellowthroats of eastern North America. The black mask of the Bahama Yellowthroat does not narrow towards the bill as it typically does in the Common. On the Andros Islands and New Providence, the crown is gray, unlike Common. Similarly, female Bahama Yellowthroats are more extensive yellow below but often have some gray on the lower belly. Songs and calls resemble those of Common, but the “tchuck” note lacks vibrato.
