Most female warblers do not sing…but there are at least 9 species who regularly do (perhaps over 20 who do on occasion). The Cape May is among them. The Cape May is also one of the warbler species in which the female has distinctly different coloration than the male…enough so that you might suspect it is a different species (especially when you find it singing :). And, to add another to the list of things the Cape May is…it is another of those warblers named for where it was first collected…in Cape May, New Jersey…even though it only appears there during migration between its wintering grounds in extreme south Florida, the Caribbean Islands and Yucatán Peninsula, and its breeding grounds in the extreme northern US (in New England and the Mid-west) and southern Canada. In fact, it was not seen in Cape May for 100 years after the first specimen was captured there and is still considered an occasional migrant in New Jersey. I found this one from the boardwalk at Magee Marsh on the Erie shore of northern Ohio during the Biggest Week in American Birding. Sony RX10iv at 600mm equivalent.
