Have you seen a flash of yellow in your yard lately?
The Wood Warbler family is famous for their diversity in plumage, song, feeding and breeding biology. All of them are small birds with long, thin bills used for snapping up insects and larvae. Perhaps one of the easiest to identify is the Yellow Warbler, which has more yellow in its plumage than any other member of the family.
In spring breeding season, males have rusty streaks on the breast and flanks, a bright yellow face with conspicuous black eyes, and yellow upperparts. They are known to build another nest on top of an old one when Brown Cowbird eggs appear in it, which can result in up to six different layers.
Yellow Warblers can be seen around the city from mid May to mid September. These birds are widespread in most shrubby and second-growth habitats in North America, where they can be seen quickly hopping from branch to branch. This bird was busily flitting from the saskatoons and lilac shrubs to the poplar trees in my yard.
