280 ViSHER, Birds of Pima County, Arizona. [july 



far too meagre knowledge of the habits and songs of many interest- 

 ing birds. 



The following list treats only those (127 species) about which 

 I believe I can contribute something. Of the other hundred ob- 

 served, Mr. Scott correctly gives their distribution, etc., and the 

 Baileys and Chapman ('Color Key' and 'Camps and Cruises of an 

 Ornithologist') have described their songs, etc., as well or better 

 than I can. 



A single asterisk follows twenty-one names and indicates that 

 this species is here reported from an altitude quite different from 

 that given by Scott. Many mountain forms were found migrating 

 along the lowlands. 



A double asterisk occurs twenty-eight times and indicates a new 

 record for Pima County. 



A triple asterisk marks nineteen species which were found 

 nesting. Mr. Scott recorded them only as migrants or winter 

 visitants. 



The Red-eyed Cowbird and the White-headed Woodpecker are 

 four times starred. The Hudsonian Godwit is also out of its pre- 

 scribed range but unfortunately the record is not absolutely certain. 



1. Colymbus nigricoUis californicus. Eared Grebe.** — Rare Migrant. 

 (Lusk.) 



2. Gavia immer. Loon.** — Tolerably common migrant. (Lusk.) 

 Lams sp. Gull. — Occasionally a gull is seen migrating. (Lusk.) 



3. Hydrochelidon nigra surinamensis. Black Tern.** — Common on 

 the few ponds in August. 



4. Pelecanus er3rthrorhynchos. White Pelican.** — Tolerably com- 

 mon migrant. (Lusk.) 



5. Ardea herodias treganzai. South-western Blue Heron. — Toler- 

 ably common summer resident. 



6. Grus mexicana. Sandhill Crane.** — Common migrant. (Lusk.) 



7. Limosa haemastica. Hudsonian Godwit.** ^ — A Godwit, very 

 probably of this species, was examined at close range, with binoculars, on 

 a pond near Tucson, September 18. The fact that Scott questions the 

 identification (Marbled) of the godwit he saw is suggestive. 



8. Totanus melanoleucus. Greater Yellow-legs. — Rare migrant 

 in spring as well as fall. 



9. Totanus flavipes. Yellow-legs.** — Tolerably common on a 

 pond near Tucson early in September. 



10. Catoptrophorus semipalmatus inornatus. Western Willet.** — 

 Occasional migrant in May about Tucson. Taken by Mr. Herbert Brown.
