Geographic Variation in Nests of Yellow Warblers Breeding in Churchill, Manitoba, and Elgin, Ontario
Nesting structures are important for successful reproduction in most birds, and, because of this, geographic variation in nest morphology and composition are usually interpreted as adaptations to breeding in different environments. We compared the structure of nests of Yellow Warblers (Dendroica pet...
