For nearly one hundred years at least this species had been considered very rare in New England, but about 1909 it seemed to become more common. In May, 1912, at Amesbury, Massachusetts, one chilly morning I found bright males scattered through the village. A cold wave, catching them in night migration, had brought them down, and they could be seen here and there on or near the ground, and in low bushes by the roadside. In the door-yards and along the streets these lovely birds hopped and fluttered fearlessly in their search for food, paying little attention to passers-by. By 1915 they had appeared more generally, and in May, 1917, they were well distributed over a large part of New England. Since that time Cape May Warblers have been not uncommon transients in certain years, and they have never been as rare as they formerly were. In migration they may be found in trees and shrubbery about dwellings and along village streets almost as commonly as in woods or in swampy thickets, where at this season they find many insects. Occasionally a few may be seen in blossoming orchards. _Courtship._--Information on the courtship behavior of the wood warblers is so scanty that it seems worthwhile to include two small items on this subject for the Cape May warbler. While watching a pair at their nest-building, Dr. Merriam (1917) observed that "on June 11 the male was seen to chase the female. The next day nest building was apparently complete. An hour's watching on the 13th also failed to show any further nest construction, although the female was frequently heard in the low growth. Once she flew ten feet up in a spruce and gave a peculiar note at the same time lifting her tail. Immediately the male flew down and copulation took place. The whole proceeding resembled very much that of the Chipping Sparrow." James Bond (1937) noted at times that, "when the female was working on the nest, the male would fly with rigid wings just above her. This was a characteristic courting display, noted with other individuals."
