Canada Warbler: Small warbler with slate-gray upperparts, bright yellow underparts, black-streaked necklace, and white vent. The eye-ring is yellow to white. Bill is gray. Pink legs and feet. Skulks in low, dense undergrowth beneath mixed hardwoods. Direct flight with quick, fluttering wing beats.
Range and Habitat
Canada Warbler: Breeds from southern Canada to northern U.S. east of the Rockies, and in the mountains to northern Georgia. Spends winters in the tropics. Preferred habitats include cool, moist woodlands with abundant undergrowth.
Canada Warblers are declining throughout the Northeast at rates of 4% to 7% per year. The causes of the declines are unknown, but loss and degradation of breeding habitat appear to be contributing factors.
The distinctive black markings across an otherwise yellow throat and breast gives this warbler the nickname of "Necklaced Warbler."
They have been seen twice in Europe. The first record was seen in Iceland, and the second was of a first-winter female which was found in Kilbaha, County Clare, Ireland in October 2006.
A group of warblers has many collective nouns, including a "bouquet", "confusion", "fall", and "wrench" of warblers.
The Canada Warbler has a fairly large range of almost 3 million square kilometers. The global population of this bird is around 1.5 million birds. It is native to much of North and Central America as well as the Caribbean. This bird has a current rating of Least Concern, although it was previously rated as Lower Risk as early as 2000. At this time, there is no concern regarding possible population declines with the Canada Warbler.
