BIRDS OF KANSAS. 037 



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 



Regulus calendula (Linn.). 



RUBY-CROWNED KINGLET.

B. 161. R. 30. C. 33. G. 14, 324. U. 749. 



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

 j^'hite 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 ou the crown. This species of Regnlus 

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

 nostrils, which was probably the reason with Cabauis 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."
