The male "Mourning Warbler" has a black breast patch, which some think justifies his somber name. Others opine that his dark hood reminds them of a mourning veil. Not many people see this bird as he scurries in the underbrush, hiding at the slightest disturbance.
Females and immatures are grey-brown on the head with an incomplete eye-ring.
Their breeding habitat is thickets and semi-open areas with dense shrubs across Canada east of the Rockies and the northeastern United States.
Calls or song.
Contrary to his name, "Mourning Warbler", this bird's song is a paean of joy as he mounts to the top of a bush or small tree to sound a loud, ringing "chirry chirry, chorry chorry".
Population and distribution.
For a summer homesite, the "Mourning Warbler" seeks overgrown clearings and upland thickets where raspberry and blackberry bushes abound. Late in the season, they head to the tropics from Nicaragua to South America.
The "Mourning Warbler" builds a bulky cradle of leaves and grass in a brier tangle or clump of ferns, where it lays four white eggs specked with brown, sometimes with black spots and scrawls.
