ORANGE-CROWNED WARBLER. 
Helmintophila celata RipGway. 
“During the seasons of migration,” says Prof. R. Ridgway in his “Ornithology of 
Illinois,” ‘this species is occasionally common, but some years appears to be very rare 
if not wanting altogether. It possesses no special characteristic of habits or song, in 
which respects it resembles the other members of the genus,” especially the Nashville 
Warbler. In the Eastern States and New England it is rare. I found it rather common 
in south-western Missouri, in northern Illinois, and in Wisconsin during the spring 
migration. In Lee Co., Texas, it was from April 6 to April 15 an abundant bird. In 
the mountainous regions of the West it seems to be more abundant than anywhere 
else. Mr. Ridgway found it very abundant during autumn in the mquntains of Nevada 
and Utah, and a rather common bird in the higher woods of the Wahsatch Mountains, 
where it was breeding. ‘Its summer home extends far to the northward, even to the 
shores of the Arctic seas, and it breeds abundantly throughout the Yukon valley in 
Alaska, quite to the shores of Norton Sound, and thence eastward to the McKenzie 
River district, from which region numerous nests have been received at the National 
Museum.”’ The domicile does not differ from those of others of this group, being 
placed on the ground under low bushes. The eggs are white, marked with spots and 
blotches of reddish-brown and purplish slate. 
A variety, the LUTESCENT WarBLeER, H. celata lutescens BREWSTER, occurs on the 
Pacific coast, eastward, during the migration, to the Rocky Mountains, and northward 
to Kadiak, Alaska. 
NAMES: ORANGE-CROWNED WaRBLER, Orange Crown. 
SCIENTIFIC NAMES: Sylvia celata Say (1823). Vermivora celata Nutt. (1840). Helmintophaga celata 
Brd. (1858). HELMINTOPHILA CELATA Rwwew. (1882). 
DESCRIPTION: Above, olive-green, lightest on the rump. Below, greenish-yellow; a concealed orange-brown 
patch on the crown. Female, similar, but with little or no orange-brown on the crown. 
Length, 4.70 inches; wing, 2.25; tail, 2.00 inches. 
TENNESSEE WARBLER. 
Helmintophila peregrina RipGway. 
The TENNESSEE WARBLER is not uncommon during the migration in the Mississippi 
valley, but in the Eastern States and New England it appears to be nowhere very numer- 
ous. I have observed it in south-eastern Texas early in April, and in south-western
