Family Syiviin#—Kinglets and Gnatcatchers. 
Regulus satrapa (748). Golden-crowned Kinglet. 
Winter resident; very common during some seasons (’92-8, 
for instance) and comparatively rare others. They are, how- 
ever, most numerous during migrations, thinning out about the 
end of October and getting numerous early in March. Extreme 
dates are September 30 (93, Gray) and April 22 (’98, Gray). 
At Washington “one was taken on April 27 (’88, Hasbrouck) ” 
(Richmond), and at Hagerstown it was noted as “staying until 
May” (Small). 
Regulus calendula (749). Ruby-crowned Kinglet. 
A common migrant; possibly a few winter with us during 
mild seasons. Noted from September 26 (’94, Resler) to Novem- 
ber 5 (92, Gray), and from April 2 (’87, Resler) to May 7 
(93). At Hagerstown, a “common migrant in March and 
April, October and November; plentiful in fall, but scarce in 
spring” (Small), At Washington “from September 25 (’87) 
to early in November, and from April 8 (’88) to May 10 (’91). 
Specimens have been taken in winter: two on December 1 
(89, C. W. Richmond; A. K.Fisher), one on December 15, ’89, 
and 2 others seen, and 1 on February 9 (91, Figgins)” (Rich- 
mond). “On December 5, 92, I saw and positively identified 
a single Ruby-crowned Kinglet in the grounds of the Depart- 
ment of Agriculture, and also saw what was presumably the 
same individual on January 5, 6 and 14, ’93, this period cover- 
ing some of the most severe weather ever known here” (E. W. 
Clyde Todd, Auk, x, 206). 
Polioptila czrulea (751). Blue-gray Gnatcatcher. 
Fairly common during summer in restricted localities, from 
April 1 (93, Gray) to September 14 (’93, Gray). At Wash- 
ington “from April 5 to September ; one was shot on No- 
vember 23, 790” (Richmond). On May 7 (’93), a nest was 
nearly finished ; May 14 (’93, Blogg) and June 4 (95, Fisher) 
are extremes for eggs. Sets are 7 of 4.
