ANDEKSON — THE BIRDS OF IOWA. 385 



hairy caterpillars, the}- never touch. The nests are placed any- 

 where about buildings and .sheds, .sometimes in trees and vines, 

 and as several broods are rai.sed in a .sea.son their increa.se in 

 numbers is exceedingly rapid. 



" At the present time (1899) it is found in every state and 

 territory except Alaska, Arizona, Montana and Nevada" 

 (Palmer); (F. M. Bailey, Handbook Bds. Wn. N. A., p. 324). 



HYPOTHETICAL LLST. 



The .species included in this list are tho.se which have been 

 taken in adjoining states, very close to the borders of Io\va, and 

 such as may at any time be expected to occur within the limits 

 of the state. A few .species, which have heretofore been reported 

 as occurring in Iowa upon what appears to be insufficient evi- 

 dence, are also relegated to this list. 



Family LARID.K. Gulls and Terns. 



1. (47). Imiks viaiiiiKs hn\n. Great Black-l)acked Gull. 

 This .species was listed by J. A. Allen (White's Geol. of Iowa, 



ii, 1870, p. 427). It is included in the Nebra.ska list on Aughey's 

 record of a .specimen shot on the Mi.ssouri River and brought to 

 Dakota City in May, 1871 (Rev. Bds. Neb., p. 19). C. K. Salis- 

 bury reported the .species as a rare transient in Blackhawk 

 county. The .species occurs on the Great Lakes in winter. 



2. (40). Rissa iridady/a {l^inn.) . Kittiwake. 



George H. Berry writes : " Rare summer resident (Dickin.son 

 county). I did not .shoot any of the birds, but from what I could 

 .see of them would place them as the Kittiwake. In 1891 they 

 bred on an island in Loon Lake, Minn., about a mile beyond 

 Spirit Lake, and I found about a dozen nests with young on a 

 .small lake about three-quarters of a mile .southeast of Spirit Lake, 

 on the prairie. They were not the Herring Gull, and from the 

 best of my recollection (the Kittiwake being very abundant on 

 the coa.st of Maine, my old home), it exactl}- resembles the Kit- 

 tiwake." The Kittiwake has been taken quite frequently on the 

 Great Lakes, but it is doubtful if it ever occurs in low^a except 

 as a rare straggler.
