Cerulean Warbler: Dendroica cerulea
Cerulean warblers are strikingly beautiful. Adult males are a vibrant blue color on their backs and heads, and white below, with a dark breast band and dark streaks. Adult females are blue-green above, pale yellowish below.
In North America, the biggest threats to cerulean warblers include the loss and fragmentation of mature deciduous forests, especially along stream valleys; shorter rotation periods and even-aged management on timber harvest lands; and perhaps the loss of key tree species due to introduced pests. In North America, conservation efforts directed at this species include land acquisition and protection.
Cerulean warblers do not breed in Florida, but may be seen in the state during their migration between breeding grounds in southeastern North America to their winter range in northern South America.
