BIRDS OF KANSAS. 635 



Iris dark brown; bill and claws black; legs and feet bluish 

 slate. 



I am unable to detect any difference in the habits, actions or 

 notes of this large form from the eastern bird, our common 

 Chickadee, and they occasionally interbreed. 



Eggs four to eight, . 62x.48; dull white, rather evenly speckled 

 with reddish brown, and a few shell stains of lilac; in form, 

 oval. 



FAMILY SYLVIIDJE. WARBLERS, KINGLETS, GNATCATCHERS. 



"Bill much shorter than head, slender, broad, and depressed at the base, dis- 

 tinctly notched and decurved at the tip. Culinen sharp-ridged at base. Frontal 

 feathers reaching to the nostrils, which are oval, with membrane above, and 

 overhung not concealed by a few bristles or by a feather. Rictal bristles 

 extending beyond nostrils. Tarsi booted or scutellate. Basal joint of middle 

 toe attached its whole length externally, half way internally. Primaries ten; 

 spurious primary about half the second, which is shorter than seventh. Lateral 

 toes equal." 



SUBFAMILY KEGULHSTJL KINGLETS. 



"Wings longer than the emarginated tail. Tarsi booted, or without scuttel- 

 lar divisions. This subfamily embraces but a single well-defined North Ameri- 

 can genus." 



GENUS EEGULUS CUVIEB. 



"Bill slender, much shorter than the head, depressed at base, but becoming 

 rapidly compressed; moderately notched at tip. Culmen straight to near the 

 tip, then gently curved. Commissure straight; goiiys convex. Kictus well pro- 

 vided with bristles; nostril covered by a single bristly feather, directed forwards 

 (not distinct in Calendula). Tarsi elongated, exceeding considerably the mid- 

 dle toe, and with scutella. Lateral toes about equal; hind toe with claw longer 

 than middle one by about half the claw. Claws all much curved. First pri- 

 mary about one-third as long as the longest; second equal to fifth or sixth. Tail 

 shorter than wings, moderately forked, the feathers acuminate. Colors, olive 

 green above, whitish beneath. Size, very small." 



Regulus satrapa LIGHT.
