Both Cape May and myrtle hawk and undertake long flights significantly more often than any of he other species. Black-throated green hovers significantly more often than the others.At this point it is possible to summarize differences in the species' feeding behavior in the breeding season. Unfortunately, there are very few original descriptions in the literature for comparison. The widely known writings of William
Brewster (Griscom 1938), Ora Knight (1908),and S. C. Kendeigh (1947) include the best observations that have been published. Based upon the observations reported by these authors, the other scattered published observations, and the observations made during this study, the following comparison of the species' feeding behavior seems
warranted.
