Northern Parula Warbler: Dr J. Murray Speirs

This is an uncommon to rare warbler in Ontario, although apparently much more common in times past.

They breed where Usnea (lichen) drapes the trees, chiefly near the influence of Lake Superior. They winter from Florida and Mexico south to the West Indies and South America.
