CRUISE OF THE STEAMER CORWIN. 93 



36. Scolecophagus carolinus {Mi'ilh). Rusty Blackbird (Tu-lu-gu-rnk). 



I saw nothing of this bird until late in the season, when a few migrants, fi-om the north 

 presumably, were noticed about the banks of the lower river and at Kotzebue Sound. 

 Two specimens; Lower Kowak, August 22-35. 



37. Acanthis linaria holbcellii (ZJ/cA HI ). Holbcell's Redpoll (Kahruk-twayuk). 



The redpolls probably breed near the coast in Northern Alaska, for during a two-montlis' 

 journey of several hundred miles through a well-diversified country I saw less than half a 

 dozen individuals, and there were no evidences that these were breeding. 



Two specimens; Upper Kowak, July 1.5. 



38. Calcarius lapponicus (£{«».). Lapland Longsplr (Eo-pdl-i/uk). 



I found this species comparatively abundant about Kotzebue Sound late in August, biit 

 saw nothing of it up the river. 



One specimen; Kotzebue Sound, August 20. 



39. Ammodramus sandvwichensis alaudinus (/JoHop.). sWestern Savanna Sparrow {0-pcil-ijuk.) 



The .savanna sparmw is a very abundant bird along the river. I did not find nests, but the 

 number of young birds shot indicate that the species bi'eeds plentifully there. 

 Six specimens; Upper Kowak, July 30-August 10. 



40. Zonotrichia intermedia i?i(i(/H'. Intermediate Sparrow (Nun-wuklAn-ruk). 



This is proliably the most abirndant sparrow in the Kowak regions. I found many young 

 birds. 



Thirteen specimens; Upper and Middle Kowak, July 7-August 18. 



41. Spizella monticola ochracea Brewst. Western Tree Sparrow {Cukcdn-ruk or f'k-jnk-nhdi-uk or Mk-uk-U'ii-yuk. ) 



Constantly associated with the two preceding species, it was almost as common botli in tlie 

 number of adults and young. 



Thirteen specimens; Upper and Middle Kowak, July 1.5-August 18. 



42. Junco hyemalis (/-ill H.). Slate-colored Sparrow {Ka-sdnu-iuk). 



Moderately common in the di-ier spriace forests. 

 Three specimens; Upper Kowak, July 20-24. 



43. Melospiza lincolni {And.). Lincoln's Sparrow {Sil-win-mfkciik). 



A solitary specimen of Lincoln's sparrow was shot on the Upper Kowak, July 20. 



44. Passerella iliaca {Men:). Fox Sparrow. 



Like the preceding, this species is represented in my collection by a single si)ecimen, the 

 only one seen. It was taken on the upper river on July 15. 



45. Chelidon erythrogaster (i?orfrf.). Barn Swallow. 



I recognized the barn swallow on several occasions as it flew with other swallows over the 

 river. 



46. CUvicola riparia {Linn.). Bank Swallow. 



Bank swallows were frequently seen on the upper river when we first arrived there, but 

 later the continued heavy rains raised the river to such a height (nearly ten feet) that their 

 tunnels were inundated and the young birds destroyed. For a week or more after this, or dur- 

 ing the first week of August, large flocks of swallows went flying everywhere about the coun- 

 try and then disappeared and were seen no more during our stay on the river. 



47. Lanins borealis Vieill. Northern Shrike. 



The only shrike seen was a young bird I shot at Kotzebue Sound August 20.
