1915.] Chapman, New South American Birds. ott 
| Type.— No. 121,454, Am. Mus. Nat. Hist., 9 ad., Savanna of Bogotdé, Col., 
Feb. 19, 1913; F. M. Chapman. Wing, 304; tail, 137; tarsus, 54; culmen, 32 mm. 
Range:— Savanna of Bogotdé, Colombia. 
_Remarks.— Only the type of this interesting and well-marked race was 
secured by our expedition. While comparison with a large series of A. f. 
flammeus indicated its distinctness, it was deemed inadvisable to describe 
it without additional specimens. Our good friend Hermano Apolinar Maria, 
Director of the Instituto de la Salle of Bogota, who has rendered us such 
valuable assistance on similar occasions, was therefore appealed to and he 
promptly sent two more females both collected on the Bogoté Savanna. 
These two birds agree with the type and thus confirm the validity of 
the characters on which the proposed new race is based. 
Other than the marked changes in appearance caused by the diminution 
of the ochraceous markings on the feathers of the upperparts, I observe no 
difference in pattern of coloration between bogotensis and true flammeus. 
Both have the markings of the wing-quills under wing-coverts, and under- 
parts essentially the same, and beyond a slight difference in size are therefore 
to be distinguished only by the much darker color above and less heavily 
feathered feet of bogotensis. 
In the restriction of the ochraceous markings above, bogotensis is nearer 
to portoricensis than to flammeus. Our two specimens of portoricensis 
are not so dark above, the wing-quills have more brown basally, and the 
under wing-coverts, as stated by Ridgway in his original diagnosis (Bull. 
U.S. N. M., IV, 1881, p. 366), are “nearly immaculate ochraceous.” 
In the darkness of its upperparts bogotensis bears some resemblance to 
— galapagoenstis, a fact to which Sharpe (Cat. B. M. Bds., II, 1875, p. 239) 
called attention many years ago. The latter, however, is smaller, has more 
ochraceous in the upperparts, has the flanks barred, and tarsi marked with 
fuscous. 
The limited number of specimens of this widely distributed owl which 
I have seen from Argentina appear to be referable to true flammeus (though 
the under wing-coverts have fewer marks). This form occurs at sea-level, 
therefore, both in the North Temperate and South Temperate Zones, while 
bogotensis occupies that little Temperate Zone island which is formed by the 
Savanna of Bogota in the Eastern Andes of Colombia.
