Several swallows sup- posed to be this species were seen April 8. Lanius ludovicianus excubitorides. White-rumped Shrike. Abundant; frequently seen perched on the topmost twig of a mesquite. Several sets of five eggs were taken in April from nests a few feet above the ground in mesquite and catclaw bushes. Vireo gflvus. Warbling Vireo. Quite common after May 3 when the first was taken. Heltninthophila celata lutescens. Lutescent Warbler. One taken in the Dragoon mountains May 4. Dendroica auduboni. Audubon Warbler. Seen occasionally through the winter and spring.

Wilsonia pusilia pfleolata. Pileolated Warbler. Seen in the cottonwoods near the house April t 5. Later it became the most common warbler. Anthus pensflvanicus. American Pipit. One was taken at Sulphur Spring March t6 and on my next visit, March 23, quite a number were seen. Oroscoptes montanus. Sage Thrasher. The sage thrasher was not uncommon through the month of April but previous to that time it was rarely seen. Mitnus polyglottos leucopterus. Mockingbird. The song of the mockingbird was first heard on the morning of April t 5. From that time on it was a source of constant pleasure. Toxostotna bendirei. Bendire Thrasher. One taken April 8 and one April 17 were the only specimens seen. Toxostotna crissale. Crissal Thrasher. Quite common. I found a nest April 3 containing two rotten eggs, at which I was surprised, as I had thought it too early for eggs. Three days later on the 6th, however, I shot a young bird just able to fly which confirmed the suspicions aroused on the 3d. Fresh eggs were taken after this, April 8, it, t5 and 20. Heleodytes brunneicapfllus. Cactus Wren. A pair reared a brood of young in a nest placed in a hole in the corner of an old house. These were the only cactus wrens seen though quite a number of their conspicuous nests were noticed in the chollas and mesquites. Salpinctes obsoletus. Rock Wren. A single specimen was taken near the house at Allaire's April 23, being the only one seen in the valley. In the Dragoon mountains, they were abundant in suitable places. Thryomanes bewicki bairdi.
