There are many versions of this little yellow warbler. This so happens to be the version that lives in the mangroves from Florida south to Columbia, including a good portion of the Caribbean islands. The chestnut cap is the trademark of the "Golden" warbler and can sometimes be the entire head of the bird is chestnut for 'Mangrove' warblers along the coast of Central and Northern South America. It is known that the gray hood or collar that is seen here is found on the Cuban birds. This individual was photographed along the mangroves at the west end of the Varahicacos Ecological Reserve on the Varadero Peninsula.
