BLACK-THROATED BLUE WARBLER

The Black-throated blue warbler (Dendroica caerulescens) is a common to fairly common breeder in BCR 14. It prefers deciduous or mixed woodlands with a thick understory of shrubs or saplings. It is listed as a Species of Greatest Conservation Need in at least one state in BCR 14.

BICKNELL'S THRUSH

The Bicknell’s thrush (Catharus bicknelli) is locally common to uncommon in BCR 14. It requires high-elevation stunted spruce-fir forests for nesting and cover. It has also been reported in low-elevation coastal softwood areas, particularly in maritime Canada. It is listed as a Species of Greatest Conservation Need in one or more states in BCR 14. Its population may or may not be declining; however, since its habitat availability is limited and fragile, it is a species of concern.

BAY-BREASTED WARBLER

The bay-breasted warbler (Dendroica castanea) is a common to rare breeder mostly in the northern part of BCR 14. It prefers second growth boreal forest containing balsam fir. It is listed as a Species of Greatest Conservation Need in one or more states in BCR 14.

AMERICAN BLACK DUCK

The American black duck (Anas rubripes) is a common to fairly common breeder in BCR 14. It uses a wide variety of fresh water habitats and nests in thick understories of shrubs or hardwood or softwood regeneration. It is listed as a Species of Greatest Conservation Need in one or more states in BCR 14. Black duck populations are declining due to habitat loss and hybridization with mallards.

ALDER FLYCATCHER

The alder flycatcher (Empidonax alnorum) is an uncommon breeder in BCR 14 with the exception of Maine where it is more common. It is listed as a Species of Greatest Conservation Need in one or more states in BCR 14.
