Range Expansion and Population Increase in North and Middle America of the White-tailed Kite (Elanus leucurus)
Various human activities have had a drastically injurious effect on many birds of prey. It is therefore gratifying to observe a very recent and dramatic increase of a raptor which, not many years ago, was considered on the verge of extirpation in North America. May, "Hawks of North America" (1935: 7-11), wrote: "The White-tailed Kite . . . is today in very real danger of complete extirpation in the United States, where it is now very rare and local. An earnest and immediate effort should be made to arouse public opinion, through education, to save the pitiful remnant of this beautiful species before it has completely vanished."
