BIRDS OF KANSAS. 637 



limb, about fifteen feet from the ground. It was partially sus- 

 pended, like the Vireos, but largely supported by the stiff branch- 

 ing twigs, within which it was well concealed, and was composed 

 almost wholly of green tree moss; roundish in shape, two and 

 a half inches deep inside, and one and a half inches in diameter 

 at the top. The outside was beautifully dotted with lichens and 

 feathers, and warmly lined with downy feathers. Eggs: .50x 

 .40, .50x.40, .50x.41, .50x.41, .50x.41, .50x.41, .50x.42, 

 .50x.42, .50x.42, .50x.43; in form, oval.

HABITAT. North America; north to the Arctic coast; south 

 to Guatemala; breeding in the higher mountains from Arizona 

 and northern borders of the United States northward; wintering 

 in the more southern States southward. 



SP. CHAR. "Above, dark greenish olive, passing into bright olive green on 

 the rump and outer edges of the wings and tail. The under parts are grayish 

 white tinged with pale olive yellow, especially behind. A ring round the eye, 

 two bands on the wing coverts, and the exterior of the inner tertials, white. 

 Male: Crown with a large concealed patch of scarlet feathers, which are white 

 at the base. Female: Without the red on the crown. This species of Regulus 

 appears to lack the small feather which, in gatrapa, overlies and conceals the 

 nostrils, which was probably the reason with Cabanis and Blyth for placing it 

 in a different genus. There is no other very apparent difference of form, how- 

 ever, although this furnishes a good character for distinguishing between young 

 specimens of the two species."

These elegant little birds are similar in habits and actions to 

 the Golden-crowned Kinglets, and were it not for their surpris-
