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 RUBRICAPILLA RUBRICAPILLA (Wilson). Nashville 
Warbler. 
Not uncommon migrant. 
The Nashville Warbler arrives from April 25th to May oth 
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.
