Archives for Watch List Species

During the breeding season, Prothonotary Warblers are inhabitants of the wet forests of the eastern U.S., with the core of their breeding range in the southeast.

The Canada Warbler inhabits shady forest undergrowth year round, making this species vulnerable to forest loss. Canada Warblers spend the majority of the nonbreeding season in the northern Andes, which is among the most threatened in the world, having experienced a 90% loss of forest due to agricultural expansion (cattle, coffee, coca) and fuel wood production.

Lewis’s Woodpecker population declines are consistent with heavy loss of ponderosa pine habitat in Arizona, British Columbia, Oregon and Washington due to fire suppression, intensive grazing, and logging.

The boldly patterned Golden-winged Warbler has experienced severe population declines across its range in recent decades, including a 98% decline in Appalachian forests, a former stronghold of the species.

The Wood Thrush has a widespread breeding distribution across the eastern United States and southern Canada, but it has experienced strong population declines throughout much of its range.
