TR, Aurora, Ont. Robbins, C. The hooded warbler has undergone a decline in population over the last several decades throughout portions of its range including New Jersey. Such declines are most likely due to habitat loss. It is listed as a Species of Special Concern in New Jersey not yet endangered or threatened but possibly on its way.
Preservation of large areas of contiguous forest and riparian forest with mature forest buffers are important for this species within its breeding range. Find Related Info : Migratory songbirds , Special concern.

In the forest undergrowth, this skulking warbler seems to call attention to itself by frequently fanning its tail quickly open and shut, flashing the white outer tail feathers. Hooded Warblers are common in moist leafy woodlands of the Southeast.
They usually stay low in the shadowy understory, foraging actively in the bushes and nesting close to the ground, although males will move up into the trees to sing. Photo gallery. This small yellow songbird is readily identified by its distinctive plumage and vocalizations. Adult males have a characteristic black hood but this feature is reduced or lacking in adult females.
The breeding range of this species has been expanding northwards for at least 40 years. The Canadian breeding distribution is restricted to southern Ontario, where it is considered to be a rare or locally uncommon breeder.
The Hooded Warbler typically nests in shrubs associated with small canopy-gaps within large tracts less than ha of mature deciduous or mixed forests.
High densities can occur following selective logging, provided many mature trees remain. On the wintering grounds, there is strong sexual segregation by habitat with males preferring closed canopy forests and females preferring more open shrubby habitats.
This insect-eating passerine begins breeding when it is 1 year old.
