76 THE CONDOR Vol. X 



Warblers are a very interesting group we admit, but neither species nor in- 

 dividuals were represented sufficiently to gain proportionate rank. Townsend 

 Warblers {Doidroica tozunsendi) I met with during the migrations, at about the 

 5000 foot level at all times. They limited themselves to such ravines as harbored 

 a growth of madrona trees. Latest spring date: May 13; fall dates: September 5 

 to 21. Audubon Warblers {Dejidroica auduboni) , found in abundance during the 

 earlier weeks of May, had all disappeared by the 20th, and no more were seen until 

 October 1, when I secured an immature $> at 5000 feet. Black-throated Gray 

 Warblers {Dendroica nigrescens) being plentiful at all elevations during my entire 

 stay, I cannot give any arrival or departure dates. But a bird secured, with ad- 

 ditional ones seen, October 28, along the Rio San Pedro, gives ground for believ- 

 ing them of very late departure from the highlands, and, with future investigation, 

 a winter resident of the valleys of southern Arizona. The Tolmie Warbler 

 ( Oporornis tolmiei) was not recorded during the spring. An adult $) on Septem- 

 ber 5, was my first fall date; for a month thereafter it was of usual occurrence from 

 where the oaks begin, up to the pines. Quite deliberate of movement, yet retiring, 

 the brushy situations at all times were chosen, in preference to the arborescent 

 growth. The commonest warbler here, the Pileolated ( Wihonia pusilla pileolata) , 

 was noted every month, only excepting June and July (absent May 26 to August 5). 



lyUcy Warblers {Helm hit hoi) hila lucice) will claim attention during their 

 season, in most any arroyo or wash between the mountains and San Pedro River, 

 but none in the mountains proper. The single exception happened on June 3, 

 which I can recall as an exceedingly warm day. Returning from a tramp about 

 the foothills, and pausing to drink at the first spring encountered, a diminutive 

 warbler, recognized as the Lucy, flew down and began quenching its thirst also, at 

 a distance of ten feet. Elevation 4200 feet, among the oaks. 



How eager I was, to make the reacquaintance of the Painted Redstart {Seto- 

 i>haga fida) after a lapse of some years. Still I believed myself doomed to dis- 

 appointment up to the 22nd of July. Then a solitary bird, and no more, until after 

 the heavy rains of the last week in August, which put the canyons in ideal con- 

 dition for this species, i. e., freshened up the mosses and lichens; brought forth a 

 heavy undergrowth; started many rivulets; and lastly, introduced innumerable 

 swarms of midges into the world to enjoy the situation. And now too, the migra- 

 tory time had arrived. So the two weeks from September 7 to 21, marked a 

 period of abundant opportunity to stud\^ this species. Nervous energy in the bird 

 is quite generally attributed in maximum to the wren, but I think I can say con- 

 fidently, that no bird coming within the scope of my observation, has a better claim 

 to a title of perpetual motion than the Painted Redstart: I have never seen it quiet 

 for ten consecutive seconds! 



Among the half dozen species of Woodpeckers, found in the Transition zone 

 at times during my visit, the Gila {Centm'us nropygialis) and Arizona {Dryo- 

 bates arizo)ice) drew the most attention from me — perhaps owing to their limited 

 distribution within our country. In midsummer an occasional Gila Woodpecker 

 ventured into the foothills, to prowl among the old mescal stalks, so numerous 

 thereabouts; later on, b}^ September 1, more were in evidence, and had pushed 

 their range up to 5000 feet greater than when in their usual retreats (lowland val- 

 leys and mesa); rarely beating a tattoo or uttering a call; dividing their time be- 

 tween mescal and Opuntia cactus; and now and then inspecting an oak, from which 

 they were generally driven away by a more pugnacious relative, the Ant-eating 

 Woodpecker {Melajierpes formicivo}'t(s) , a species that seemed as numerous as the
