Harris Birds of the Kansas City Region. 315 



in May and leaves early in September. It is most numerous 

 during the second week in May when the bulk of the migrants 

 pass. At this time it is evenly distributed over the wooded 

 sections of the entire county. In the breeding season it is 

 found only about rocky ledges bordering thick timber, pre- 

 ferably near creek bottoms or damp ravines. Such conditions 

 are found in and about Swope Park where the dry monotonous 

 song of this warbler is heard regularly during summer. This 

 song is very similar to that of the Chipping Sparrow but is dis- 

 tinguishable from it in being higher pitched and more rapid in 

 execution. The songs, too, are never heard in the same en- 

 vironment. 



VERMIVORA PINUS (Linn.). Blue-winged Warbler. 

 Rather rare summer resident. 



The Blue-winged Warbler arrives during the last days of 

 April and during the next ten days northbound migrants are 

 present in numbers in the wooded regions of the county. 



Its buzzing notes are heard all summer in the less frequented 

 woods of Swope Park where it seems to be increasing in num- 

 bers during recent years. With the exception of some of the 

 wilder bluff regions, the conditions for the successful raising 

 of its young are more favorable in Swope Park than in any 

 other region of the county. 



VERMIVORA CHRYSOPTERA (Linn.). Golden-winged Warbler. 

 Extremely rare migrant. 



Though there is but one record of the local occurrence of this 

 warbler (May 9, 1889, Bush) it is not considered as merely acci- 

 dental. It migrates regularly through the eastern part of the 

 state and occurs sparingly south of this district. It is hoped 

 that students may be able to secure and transmit further data 

 regarding this species. 



VERMIVORA RUBRIC APILLA RUBRIC APILL A (Wilson). Nashville 

 Warbler. 

 Not uncommon migrant. 



The Nashville Warbler arrives from April 25th to May 5th 

 and is most numerous during the second week in May. The 

 latest spring record is May 22, 1916, which is an extremely late 

 date. The returning migrants pass through during the last 

 half of September.
