Cerulean Warbler (Dendroica cerulea)


The Cerulean Warbler (Dendroica cerulea) has been identified as a focal species of management concern due to a range-wide population decline of 3.2% per year on the breeding grounds for the period 1966-2005, the steepest decline for any warbler species in North America, and due to threats to its breeding and wintering habitats. Primary factors driving population declines appear to be loss and fragmentation of breeding habitats such as mature deciduous and riparian forests, prevailing silvicultural practices, loss of key tree species on breeding grounds, and modification of montane subtropical Andean forests on wintering grounds.
