Distribution
Breeds within North America from Alaska east across Canada to Newfoundland and south to southern California, northern Oklahoma, and northern Georgia; local in southern Florida; these subspecies which belong to the S. p. aestiva group of subspecies which winters in tropics. Additionally found in a number of largely non-migratory subspecies in the Caribbean (the S. p. petechia = "golden warbler" group), and in Mexico, Central America and northern South America (the S. p. erithachorides = "mangrove warbler" group). In total, there are thirty-four subspecies. The three groups mentioned have previously been considered separate species but are now considered one wide-ranging species.
Accidental (S. [p.] aestiva) to Greenland (2 records), Iceland (1 record), and Great Britain (3 records).
Taxonomy
Now often split in two species, American Yellow Warbler (Setophaga aestiva) and Mangrove Warbler (Setophaga petechia)2.
Formerly placed in the genus Dendroica.

Habitat
In the US, inhabits moist thickets, especially along streams and in swampy areas, gardens, overgrown pastures, and woodland edges, it is more limited to riparian habitat in the west than the east.
The Mangrove Warbler is sometimes further subdivided into Mangrove Warbler (S. p. erithachorides group) mainly in mangroves, and Golden Warbler (S. p. petechia group), which exhibits geographical variation in its habitat choice, ranging from mangroves to coastal scrub to highland moist forest depending on the island.
Behaviour
Breeding
4 or 5 pale blue eggs, thickly spotted with brown, in a well-made cup of bark, plant fibers, and down, placed in an upright fork in a small sapling.
The main species to be paratisized by cowbirds (Brown-headed Cowbird in temperate North America and Shiny Cowbird in tropical areas). If the female finds an alien egg in the nest she will cover it and lay another clutch.
Vocalisation
Song: Cheery, melodic sweet-sweet-sweet, sweeter-than-sweet; there is some geographical variation
Call: A sharp chip
