Deadrcdca, midubom auduhoni. — Audubon's Warbler. 



Abundant. The February birds were all in dull, streaked win- 

 ter dress, the March birds molting. 

 Oeotlilypis tricJias subsp. — Tellow-throat. 



First seen March 17. Mt. Willard writes me that the " early- 

 spring birds appear to be migrants on their way north and differ- 

 ent from the breeding ones." 

 Toxostoma curvvrostre 'pahneri. — Palmer's Thrasher. 



Abundant. In full song and starting nest building when we ar- 

 rived January 25. Said to be quite harmful in the fruit season; 

 at one ranch some 200 were shot one spring in the strawberry and 

 dewberry patches. Some fifteen nests were found in an area half 

 mile square adjoining town. All were in the cholla cacti and 

 contained usually three eggs ; though often only two. March 5, 

 two tiny black-haired young, although most of the nests contained 

 complete sets. Their nests are large and bulky, average inside 

 measurements 3.5x4.00x3 inches deep. Besides fine stems and root- 

 lets the nests often contained hair, feathers, and old rope and twine. 

 One bird taken had its leg off at the knee joint and was quite 

 lousy. 

 Toxostoma' 'bencUrei. — Bendire"s Thrasher. 



Not so common as Palmer's. April 3d, first set of two eggs, in- 

 cubation started. The average inside measurement of nests were 

 3.5x3.5x2.5 inches deep, and they contained string, cotton, hair, 

 cheesecloth, chips of newspaper and a few feathers. The stomach 

 of the one specimen taken contained the elytra of small black 

 beetles, white larvae and some unknown pupse.^ 

 Heleodytes hrunneicapillus cousei. — Cactus Wren. 



Nesting commonly in the cacti out on the mesa. April 6, nest 

 with three young ready to fly; nest with four young about five 

 days old; nest with three eggs fresh. The sides of telephone poles 

 and roofs of buildings are favorite vantage points. 

 Salpinctes odsoletus oisoleUis. — Rock Wren. 



Common on rocky hillsides. One came regularly to search the 

 woodpile for grubs after I had split the wood each morning. I 

 was told of a nest of this species that had three nails built into it! 

 Reffiiliis calendula calendula. — Ruby-crowned Kinglet. 



Became abundant after February 15 ; quite common before this 

 date. 

 PoUoptila cwrulea ohscura. — Western Gnatcatcher. 



This form, as well as P. plumhea, were common at all times rov- 

 ing over the mesa. The stomach of one specimen was full of gnats, 

 and its plumage full of lice.
