Yellow-throated warblers will occasionally hybridize with northern parulas (Setophaga americana), resulting in a hybrid species known as Sutton's warblers. [5] Sutton's warblers lack the black streaks bordering the breast indicative of yellow-throated warblers, and have a suffused greenish-yellow wash on their back, which is also not indicative of yellow-throated warblers.

Conversely masked yellowthroat can be split to three or even four species. The name 'yellowthroat' is sometimes used as an alternate name for the yellow-throated leaflove. [2] The geographical isolation of the various populations of this mainly sedentary group has led to its genetic divergence and speciation.
The common yellowthroat (Geothlypis trichas), also known as the yellow bandit [2] or Maryland yellow-throat, [3] is a New World warbler. It is an abundant breeder in North America , ranging from southern Canada to central Mexico .
The mangrove warbler (erithachorides group; 12 subspecies [4]) tends to be larger than other yellow warbler subspecies groups, averaging 12.5 cm (4.9 in) in length and 11 g (0.39 oz) in weight. It is resident in the mangrove swamps of coastal Middle America and northern South America; S. p. aureola is found on the oceanic Galápagos Islands . [ 4 ]
The palm warbler is a member of genus Setophaga. Setophaga is a genus of birds of the New World warbler family Parulidae. It contains at least 34 species.The Setophaga warblers are an example of adaptive radiation with the various species using different feeding techniques and often feeding in different parts of the same tree.
Its members occur in Eurasia, ranging into Wallacea and Africa (and the Arctic warbler breeding east into Alaska). Most live in forest and scrub and frequently catch food on the wing. Wood warbler, Phylloscopus sibilatrix (A) Yellow-browed warbler, Phylloscopus inornatus (A) Willow warbler, Phylloscopus trochilus (A)
The masked yellowthroat (Geothlypis aequinoctialis) is a New World warbler. It has a number of separate resident breeding populations in South America. The black-lored yellowthroat and southern yellowthroat were formerly considered subspecies. The breeding habitat is marshes and other wet areas with dense low vegetation. The masked yellowthroat ...
Audubon's warbler (Setophaga auduboni) is a small bird of the family Parulidae. At one time considered a distinct species, discovery of a hybrid zone between it and the myrtle warbler in 1973 has led to it being classified as a subspecies of the yellow-rumped warbler. [1]
