FAUNA OF THE ALEUTIAN ISLANDS AND ALASKA PENINSULA 81 



lapping in range. On June 5, 1937, Steenis and I observed 3 teals 

 at a small pond on Kiska Island — at least 2 were males in bright 

 plumage. One was clearly A. crecca, with a plain breast and a 

 light-colored scapular streak. The other bird lacked the scapular 

 streak, and plainly showed the crescent on the side of the breast. 

 We both saw these markings, but we failed to note the markings 

 of the third bird. It may have been a female. It is interesting 

 to note that both species of teals occur on the Pribilofs. 



Cahn, writing of his observations at Unalaska Island during 

 the war years, says of the green-winged teal : "Observed in every 

 month of the year except August in four years of observations ; 

 inhabits the same area as A. crecca, but more common." Taber 

 did not record it as being present in winter at Adak. 



Because of the difficulty of identification in the field, and be- 

 cause females of the two forms are indistinguishable, even with 

 specimens, there is confusion about their ranges and the extent of 

 territorial overlapping. Until more collecting is done, and be- 

 cause specimens of nimia east of Unimak are lacking, we may 

 assume for the present that the birds of Alaska Peninsula are 

 chiefly carolinensis. They occur in suitable locations along the 

 peninsula. In 1925, they were noted on Unimak Island and 

 Izembek Bay. In 1936, we were informed by residents that teals 

 nest up the river from Nelson Lagoon, and we saw at least two 

 teals at Ugashik River on May 29, 1936. Osgood (1904), how- 

 ever, found teals scarce in the interior of the base of Alaska 

 Peninsula, and says, 



One old female was seen on the Nogheling River July 21, and no more 

 appeared until we neared the coast on the lower Nushagak River. Immense 

 flocks were seen in late September in the vicinity of Nushagak. McKay 

 obtained several specimens at Nushagak and at Ugashik. 



The National Museum has a male green-winged teal that was 

 taken at Nushagak, May 6, 1883, by Paul J. Kojevnikoff. 



Cahalane (1944) has observed the green-winged teal on the 

 mainland only once positively : a flock of 12 was seen September 

 24, 1940, near the mouth of Savanoski River. 



Gabrielson saw several green-winged teals, obviously with 

 broods, up the Kvichak River, July 23, 1940. On April 27, 1942, 

 he positively identified 21 of these birds at King Cove, and later 

 he saw many more at Cold Bay. 



Green-winged teals occur on Kodiak Island, according to Fried- 

 mann (1935) and Howell (1948). Cahalane and Gabrielson 

 found them to be numerous in the Kodiak-Af ognak area, but there 

 are no records for the rest of the territory under discussion.
