Harris—Birds of the Kansas City Region. 331 
Family Sytvupar. Kinglets and Gnateatchers. 
Subfamily Regulinae. Kinglets. 
REGULUS SATRAPA SATRAPA Lichtenstein. Golden-crowned King- 
let. 
Common migrant and not uncommon winter resident. 
Wintering Golden-crowned Kinglets may be found in the 
wooded bluff and bottom regions, in the cemeteries, in the tim- 
ber along the Blue and Brush Creek, in the parks and in wooded 
places at the edges of the prairie country. They arrive from 
the north usually between the 5th and 10th of October (Sept. 
24, 1904, and Sept. 3, 1906, the latter a very exceptionally early 
date) and the bulk of the migrants are present during the sec- 
ond and third weeks of the month. The spring movement is 
noticeable during the first three weeks of April, when great 
numbers of these tiny birds pass through the city. None have 
been noted later than April 26th. 
REGULUS CALENDULA CALENDULA (Linn.). 
CoRTHYLIO CALENDULA CALENDULA (Linn.). Proposed 1917. 
Ruby-crowned Kinglet. 
Common migrant. 
The latest fall records for the Ruby-crowned Kinglet are De- 
cember 24 and 25, 1916, when a small troop was seen in the 
Missouri bottom timber. These birds probably did not remain 
throughout the later cold periods of the winter, but moved on 
further south. They arrive in the spring with the Golden 
crowns, but remain later, stragglers having been noted as late 
as past the middle of May (May 18, 1905, and May 17, 1916) 
and fairly regularly during the first week of the month. Fall 
dates are about the same as for the other kinglet. 
They frequent timbered places and are to be looked for in 
the same localities as the Golden-crowns. In migration they are 
common in the trees and thickets of the outlying residence dis- 
tricts. 
Subfamily Polioptilinae. Gnatcatchers. 
POLIOPTILLA CAERULEA CAERULEA (Linn.). Blue-gray Gnat- 
catcher. 
Common migrant and not rare summer resident. 
The Gnateatchers arrive from the 11th to 20th of April
