Family SYLVIID^E Kinglets and Gnatcatchers. 

 Regulus satrapa (748). Golden-crowned Kinglet. 

 Winter resident; very common during some seasons ('92-3, 

 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 ('93, 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). Kuby-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 caerulea (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, '90" (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.
