The Chats disappear from their breeding stations early in 
August (August 4, 1904, family party) and the fall migration 
is not noticeable, as the birds are then silent and secretive. 
WILSONIA CITRINA (Boddaert). Hooded Warbler. 
Rare visitant and possible occasional breeder. 
The few local records of this warbler are, with one exception, 
from the timbered regions of the Missouri bottoms and are be- 
tween the 8th and 25th of May. On May 25, 1916, a pair seen 
near Independence may have been breeding. 
WILSONIA PUSILLA PUSILLA (Wilson). Wilson’s Warbler. 
Not uncommon migrant. 
The Wilson’s Warbler is present from May Ist to 20th and 
again during the first week or ten days of September. It seems 
to prefer the upland wooded regions, since there are but three 
records from the bottom lands. It passes through regularly on 
both spring and autumn migration, but is never present in very 
great numbers. 
WILSONIA PUSILLA PILEOLATA (Pallas). Pileolated Warbler. 
Occasional migrant. 
Only one Pileolated Warbler has been taken in the county; 
near Independence (Ridgway, Birds of North and Middle Amer- 
ica, U. S. N. M. Bull. No. 50, Vol. 2, p. 712). A specimen was 
taken by Bunker and Wetmore near Lawrence, Kansas, on Octo- 
ber 17, 1908. 
WILSONIA CANADENSIS (Linn.). Canada Warbler. 
Rare and irregular migrant. 
During some years a few of these warblers pass this way and 
during others none are seen. Their nearest regular migration 
route, where they pass in great numbers, is the valley of the 
Mississippi River. The latest record for this species is one bird 
seen on May 13, 1916. 
SETOPHAGA RUTICILLA (Linn.). Redstart. 
Very common migrant and fairly common summer resident. 
Redstarts arrive from the 25th to 30th of April and leave 
during September. In early May, when the migrants are most 
numerous, they are present in all parts of the county in wooded 
places and may be looked for in all the city parks and along the
