Canada Warbler (Cardellina canadensis)



Canada Warbler (Cardellina canadensis) is typically most abundant in moist, mixed coniferous-deciduous forests with a well-developed understory. They nest in dense vegetation, often in areas with mosses, ferns, and decaying stumps or logs. See the species guidance document for avoidance measures and management guidance from the Natural Heritage Conservation Program. This species is not actively tracked in the Natural Heritage Inventory Database, but it could be tracked in the future if there is further evidence of its decline.
