THE. CO.IB.OR Volume XIV Nlarch-?pril, 1912 Number A WEEK AFIELD IN SOUTHERN ARIZONA By F. C. WILDARD WITH SEVEN PHOTOS BY THE' AUTHOR S DISTANT fields look the greenest, so the giant mesquites and sahuaros in the vici'nity of Tucson seemed more inviting than the for- ests of the Huachuca Mountains where I was collecting rather unsuccessfully at the time. Consequently, on May 20, 1911, I set out with my Mexican moso, George. We left Berner's in Ramsay Canyon at six A.M. and, as the machine ran well, were thirty-two miles on our journey by nine o'clock in spite of some very rough going. At this point a defective trans- mission gear broke and we began repairs. I will not inflict on the reader the way we passed the balance of the day. A sixteen mile walk, a luckily found telephone and some accommodating friends from Tombstone furnished a new gear and at 7:30 that evening we were on our way once more. We had had little chance to look for .birds but saw a few. Scorched Horned Larks (Otocoris alpestrls adusta) were very numerous and evidently nesting. I saw one carrying grass and found its partially completed nest. While walking to secure assistance I also found a nest of the White-necked Raven (Corvus cryptoleucus) containing seven fresh eggs. The nest was placed in a tall' yucca standing out on the mesa. Farther on I encountered some full grown young Western Horned Owls (Bubo virginianus pallescens) in a grove of giant cottonwoods. They appeared to have been raised in an old hawk's nest in the top of one of the trees. Here I also met the Vermilion Flycatcher (Pyrocephalus rubinus mexicanus), Ash-throated Flycatcher ( Myiarchus cinerascens), Lucy Warbler (Vermivora luciae), Sonora Yellow Warbler (Dendroica aestiva sonor- ana), Western Kingbird (Tyrannus verticalis), Say Phoebe (Sayornis sayus). White-winged Dove ( Melopelia asiatica), Mourning Dove ( Zenaidura macroura carolinensis), Mexican Ground Dove (Chaemepelia p. pallescens), and Desert Sparrow Hawk ( Falco sparverius phalaena).
