to Labrador and south to southern California, southern Illinois, and 

 tidewater areas of Virginia. In Asia it winters south to northern 

 India and southeastern China and on the Pacific coast of North 

 America winters as far south as Baja California and Oaxaca (AOU, 

 1957). 



Skylark Alauda arvensis pekinensis 



Two small dark birds with white outer tail feathers were seen on 

 Green Island, Kure Atoll, for over a week before a specimen (USNM 

 493504) was finally collected Oct. 7, 1963. The bird, a female, flushed 

 with a group of golden plovers from a hard-surfaced roadway. 



The specimen was subsequently referred to Dr. George E. Watson 

 for subspecific determination. He informed us (pers. comm.) that 



the Skylark introduced on the Hawaiian Islands is usually listed as "probably 

 Alauda a. arvensis," the European population, which is dark brown above and 

 rich rufous buff below. The specimen from Kure, however, has the black central 

 portions of the back feathers far more extensive than in any European specimens 

 and in this character resembles specimens from western China. Wing length (114 

 mm in 9 ) and its pointed shape (fourth primary from outside 8 mm shorter 

 than third) agree with the population pekinensis which breeds in northeastern 

 Siberia, Kamchatka, and the Kuriles. 



Skylarks (presumably Alauda a. arvensis) were introduced to the 

 main Hawaiian Islands from England and New Zealand in the late 

 19th and early 20th centuries. A number of birds thought to be 

 A. a. japonica also were introduced to these islands in 1934 but did not 

 become established (Bryan, 1958). 



Barn Swallow Hirundo rustica gutteralis 



(Swallow) 



Three POBSP personnel saw two barn swallows on Green Island, 

 Kure Atoll, Sept. 25, 1964. Both were subsequently shot, but the 

 specimens fell into dense vegetation and could not be found. On 

 Mar. 27, 1965, Wirtz collected a barn swallow (USNM 495966, an 

 unsexed specimen) that Wetmore later identified as H. r. gutteralis. 

 Still another barn swallow was seen on Eastern Island, Midway Atoll, 

 Feb. 13, 1965 (Anderson), and possibly on Mar. 1, 1963 (Kepler). 

 No barn swallows have been seen or collected previously in either the 

 main Hawaiian or Hawaiian Leeward Islands. 



The race H. r. gutteralis is found on migration in Japan and the 

 Ryukyu, Bonin, Volcano, and Caroline Islands (Vaurie, 1959), sug- 

 gesting that Wirtz's specimen may have been a straggler from 

 the northwest.
