Magnolia Warbler

Scientific name: Dendroica magnolia

The abundant Magnolia Warbler is boldly patterned in yellow, black, and white, and is common across eastern North America during migration. The very dense, young conifer habitat in which Magnolia Warblers nest make studying its breeding ecology difficult, and much remains to be learned about them.

Several studies have noted an apparent increase in nest parasitism by Brown-headed Cowbirds, although none have determined what effect it may be having on Magnolia Warblers. Banding data suggest that individuals return to the same breeding and wintering areas annually, and the oldest known Magnolia Warbler was nearly seven years old.
