Species Spotlight: The Yellow Warbler
The Yellow Warbler (YEWA) is well known by birders across Ontario, being one of most widespread and abundant breeding songbirds, it’s range extends from Point Pelee all the way up to Hudson Bay! In fact, Yellow Warblers have the broadest distribution of any Warbler in the genus Setophaga (which contains most of our Warbler species), and can be found in every state and province of the US and Canada. Their preferred nesting habitat is along wetland edges (especially where willows are found) and early successional forest, where they construct cup nests right around eye level.
Despite being such a colourful and easy to observe species, Yellow Warblers are often overlooked because they are so abundant, passed over in favour of more uncommon warblers.
Yellow Warbler is similar in appearance to female/immature Wilson’s and Hooded Warblers, but note the yellow on the flight feathers and the yellow tail. YEWA is also brighter yellow than the other warblers with yellow plumage.
Here in Ontario YEWA is one of the earliest migrant warblers to leave the province, with most departing between the 2nd week of august and 1st week of September. In regions further away from the southern Great Lakes, you’re unlikely to even encounter a YEWA after August. In fact even now they could be on the move!
