Palm Warblers migrate through our area in May as they head to their breeding grounds in Canada that stretch from Alberta to the Maritimes. They only breed in the northern portion of Maine and the southern shore of Lake Superior in the US. They winter along the US coast from North Carolina to Texas, the Caribbean islands and part of Central America. (Note: I use the Cornell Labs site for my map information.) They are an olive-brown above and yellow below with some rusty striping. They have a rusty cap and bright yellow band above the eye. Unlike most warblers that inhabit the canopy, Palm Warblers feed on or close to the ground. Like all warblers, they are very active and flit around in the foliage looking for insects. It takes a little luck to catch them in the open for a photo.
