[edit] Taxonomy

This is a monotypic species^[1].
Formerly placed in genus Dendroica.

[edit] Habitat

The breeding habitat is the edges of coniferous woodland, especially Black Spruce.

[edit] Behaviour

[edit] Breeding

They nest in dense foliage near the trunk of a conifer, laying 4-9 eggs in a cup nest.

[edit] Diet

Insectivorous, and lay larger clutches in years when Spruce Budworm is abundant. They pick insects from the tips of conifer branches or fly out to catch insects in flight. They also feed on berry juice and nectar in winter, and have, uniquely for a warbler, a tubular tongue to facilitate this.
