Setophaga petechia aureola
Canario María / Reinita amarilla
The yellow warbler in the Galapagos Islands is considered a sub-species of Setophaga petechia, along with a population found on Cocos island, Costa Rica. It is thought to have colonised the Archipelago less than 300,000 years ago, making it a relative newcomer.
As suggested by the name, these birds are bright yellow. Males have a red cap during the breeding season and red streaks on their chests. Females either have pale or no streaks. Juveniles are generally duller in colour.
