1914 BIRDS OF ARIZONA 11 



13. Phalacrocorax auritus albociliatus Ridgway. 



FARALLON CORMORANT. 



Synonym Graculus dilophus. 



Status Mentioned by Cones (i866a, p. 100) as occurrmg~on the lower 

 Colorado River. Seen at various points along the river between Laguna Dam 

 and Yuma, in April and May, 1910 (Mus. Vert. Zool.). 



14. Pelecanus erythrorhynchos Gmelin. 



AMERICAN WHITE PELICAN. 



Synonym Pelecanus trachyrhynchus. 



Status The numerous records would indicate this species to be of common 

 occurrence on the Colorado River, and on the lower Gila River, at all times of 

 the year except midsummer. Except for one record from Tucson (Sloanaker, 

 1913, p. 195), it has apparently not been seen elsewhere in Arizona. 



15. Mergus americanus Cassin. 



AMERICAN MERGANSER. 



Synonym Merganser am ericanus. 



Status Mearns (18903, p. 50) speaks of this species as breeding in the 

 Mogollon Mountains, in the streams tributary to the Salt and Verde rivers, and 

 also at Fort Verde. Scott ( 1886, p. 384) found it rare on the San Pedro River 

 in January. 



1 6. Mergus serrator Linnaeus. 



RED-BREASTED MERGANSER. 



Synonym Merganser serrator. 



Status Merriam observed a few individuals at the bend of the Colorado, 

 and at the mouth of Beaverdam Creek, northwestern Arizona, in May, 1891 

 (Fisher, i893b, p. 15). This is the only published record of the occurrence of 

 the species in Arizona. Observed on the Colorado River, near Needles, February 

 18, and at Chemehuevis Valley, March 8, 1910 (Mus. Vert. Zool.). Two were 

 shot by F. N. Wolcott from a flock of four, near Fairbanks. April 8, 1911 (F. 

 C. Willard, MS). 



17. Lophodytes cucullatus (Linnaeus). 



HOODED MERGANSER. 



Status Known only from the record by Coues (1868, p. 84) of its occur- 

 rence at Camp Grant; and by Scott (1886, p. 384) of an immature female in the 

 collection of Herbert Brown, taken near Tucson, December 5, 1885. A lone bird 

 was shot by F. N. Wolcott on the San Pedro River in the fall of 1896 (F. C. Wil- 

 !anl, MS). 



18. Anas platyrhynchos Linnaeus. 



MALLARD. 



Synonym Anas boschas. 



Status A common winter visitant in suitable localities in southern Arizona, 

 usually along the larger streams. Mearns found it in the Mogollon Mountains 

 in May and June, so it probably breeds, though in limited numbers, in places 

 where conditions are favorable.
