WILLARD I WAS particularly impressed on my arrival in Tombstone some years ago, by the almost total absence of trees. A few scattering umbrella trees with a scant score of small cottonwoods were all that graced the city except a cluster that stood by themselves at the northern edge. The residence of Mr. F. N. Woleott is shaded by several good-sized cotton- woods with a fringe of small umbrella trees and mulberries lining the fence. A couple of fig trees, a peach and a weeping willow complete the list which is pieced out by climbing roses and various other climbing vines. Numerous small birds find this haven as grateful, apparently, as we of the human kind. I was much interested this past year in the numerous bird homes built there. A pair of Vermillion Flycatchers had their first nest on one of the branches of the largest cottonwood, about forty feet from the ground. In a honeysuckle almost under their domicile were two nests of the House Finch, while two others were in a large rose covering one side of the house. In a dead stub of the willow a Baird Woodpecker reared a hungry brood. Another tall cottonwood was wel tenanted with a pair each of the Cassin Kingbird, Bullock Oriole, Arizona Hooded Oriole, and several pairs of House Finches whose exact number I was never able to determine. A Costa Hummer had her nest in a smaller. cottonwood near by. A litfie later several pairs of Canyon Towhees forsook the brush of the adjacent gulches and gathered among these trees. One cottonwood held three occupied Canyon Towbee nests and two of the Arizona Hooded Oriole at one time in June, and at the same time there were three other occupied nests of the Canyon Towbee
