Swainson's Warbler © ibtimes.co.uk

Vagrant to Colombia, Dominican Republic, Puerto Rico (NB), Venezuela, Virgin Islands (U.S.).

Affinities not known. Genus has been merged with Helmitheros but, despite superficial similarities, the two are apparently not closely related. Recent studies indicate that it is genetically close to Vermivora cyanoptera and Golden-winged Warbler (Vermivora chrysoptera) and to Prothonotary Warbler (Protonotaria citrea). Birds breeding in Appalachians described as a geographical subspecies, alta, supposedly whiter below and browner (less olive) above in worn spring plumage; in fresh autumn plumage, however, more or less inseparable from lowland birds.
