Eastern North America; winters mountains of Colombia to Venezuela and Bolivia


Breeds in eastern North America. Their breeding range extends from Missouri and Minnesota in the west to New England in the east, and from Ontario south to Tennessee and North Carolina. The heart of their range is the Appalachian Plateau in Ohio, Pennsylvania, and West Virginia.

Winters in the mountains from Colombia to Venezuela and Bolivia.


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


Mature deciduous forest, mostly in damp areas or near swamps.


Cerulean Warblers have declined rapidly in recent decades. Data from the Breeding Bird Survey indicates a loss of about 80% of the population over the last 40 years. This rate of attrition is the highest for any warbler species. Loss and fragmentation of forest habitat on both the breeding and wintering grounds is the most likely cause for the decline.



The cup nests are placed on a horizontal branch high in a hardwood tree, in the upper canopy of old growth deciduous forests.


The diet includes insects.


Song: 3-5 notes on a single pitch followed by a buzzy ascending trill.
