Why they matter
The black bib of the male reminded early naturalists of mourning clothes, giving the bird its name. It depends on thickets for nesting and migration.
Reproduction and lifecycle
Nest — A cup on or near the ground
Eggs — Usually three or four
Incubation — About 12 days
Chicks — Fed by both parents
Lifespan — Several years
Living around people
- Thickets are important on migration.
Misconceptions
- Grey-hooded warblers are all the same. Mourning and Connecticut warblers are told apart by the eye-ring.
