Most warblers go over the Canada border to nest, but there are many records of the nests of this species in the Alleghanies as far south as Georgia, in the Catskills, in Connecticut, northern Minnesota and Michigan. Laurel thickets and moist undergrowth of woods in the United States, and more commonly pine woods in Canada, are the favorite nesting haunts. A sharp zip, zip, like some midsummer insect's noise, is the bird's call-note, but its love-song, zee, zee, zee, or twee, twea, twea-e-e, as one authority writes it, is only rarely heard in the migrations. It is a languid, drawling little strain, with an upward slide that is easily drowned in the full bird chorus of May.
