 Until recently considered a non-sexually dimorphic subspecies of the Lesser Antillean bullfinch ("Loxigilla noctis"), the Barbados bullfinch ("Loxigilla barbadensis") has recently been elevated to species level.There are two species of tyrant flycatcher found on the island, the grey kingbird ("Tyrannus dominicensis") which is quite common; often seen perched on power lines,and the Caribbean elaenia ("Elaenia martinica") which is more rare.Representatives of the family Columbidae include the zenaida dove ("Zenaida aurita"), common ground dove ("Columbina passerina"), scaly-naped pigeon ("Patagioenas squamosa"), and the ubiquitous rock pigeon ("Columba livia").
