In addition of nominate race Dendroica adelaidae living on Puerto Rico and Vieques islands, there are two subspecies.
Race subita which lives in Barbados resembles nominate, but its upperparts are more brownish-grey. It lacks the black stripe on the hood side, and its double wing bar is duller. It has less white on the tail. Wings and tail have the same size that nominate race.
Race delicata which lives in St Lucia is larger. Its upperparts are darker and brighter bluish-grey. The head pattern is more conspicuous: broader and more conspicuous lateral black stripe on the hood, entirely yellow eyebrow, and yellow patch below the eye. We can see sometimes some fine black streaks on back and hood.

Adelaïde Warbler’s call is a sharp “chick”. Song is variable with ascending and descending trill.
It sings at any time of year, but it sings strongly into late morning.
Adelaïde Warbler lives in dry forests, lowlands, and moist forest areas. They like tangles of vines and thickets.
It is common in dry scrublands on south coast, and in thickets on north coast. We can found a small number of birds in mountains.
Adelaïde Warbler lives in Porto Rico, but also in St Lucia, and Barbuda.
Adelaïde Warbler feeds on insects, and gleans them at middle and higher elevations in trees.
It travels with other species such as Puerto Rican Todies, vireos and other warblers.
