Regulus cuvieri, Aud. 



CUVIER'S KINGLET. 



Eegulus cuvieri, Aud. Oni. Biog. I, 1832, 288, pi. Iv, etc. — Baiud, Birds N. Am. 1859, 

 228 ; Rev. Am. Birds, 66. 



Sp. Char. Size and general appearance probably that of R. satrapa. A black band on 

 the forehead passing back, through and behind the eye, separated by a grayish band from 

 another black band on the crown, which embraces in the centre of the crown an orange 

 patch. Length, 4.25 inches; extent of wings, 6. 



Hab. " Banks of Schuylkill River. Penn. June, 1812." Aud. 



This species coutiuues to be unknown, except from the description of Mr. 

 Audubon, as quoted above. It appears to differ mainly from R. satrapa in 

 having two black bands (not one) on the crown anteriorly, separated by a 

 whitish one ; the extreme forehead being black instead of white, as in 

 satrapa. The specimen was killed in June, 1812, on the banks of the 

 Schuylkill Kiver, in Pennsylvania.

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 and young without the red on 

 the crown. Length, 4..50 ; wing, 2.33 ; tail, 1.85. 



Hab. Greenland ; whole of North America, and south to Guatemala. Oaxaca (high 

 region, November), Sclater. Xalapa and Guatemala, Sclater. 



This species of Regulus appears to lack the small featlier which, in satrapa, 

 overlies and conceals the nostrils, wliich was prol)ably the reason with Cabanis 

 and Blyth for placing it in a different genus. There is no other very apparent 

 difference of form, however, although tliis furnishes a good character for dis- 

 tinguishing between young specimens of the two species. 



Habits. Much yet remains to be learned as to the general habits, the
