Owl. 
According to Mr. Aiken, none of these Owls are found at 
Colorado Springs in the winter, indicating that this and the 
preceding species perform a slight migration.

The seventh, eighth and ninth specimens taken in the 
United States outside of Colorado are noted by Mr. Manly 
Hardy, Brewer, Me., who writes: “I have an adult female and 
a fully grown young Flammulated Screech Owl taken in 1883 
at Santa Fe, New Mexico, by Chas. H. Marsh. Also an adult 
male taken in the Huachuca Mountains of Arizona by a Mr. 
Ivusk, August 24, 1895.” 
The twelfth and thirteenth specimens for Colorado are re- 
corded by Capt. D. B. Ingraham, who took a set of two fresh 
eggs at Beulah, May 27, 1897, ^9 ^ set of three 
eggs slightly incubated. The females were secured in both 
cases and identified by Prof Allen. (Auk, XIV. 1897, p. 403). 
A female Flammulated Owl was shot by Mr. W. A. Sprague 
near Boulder, September 22, 1897. The skin was sent to the 
present writer for identification. This makes the fourteenth 
specimen for Colorado and the twenty-third for the United 
States. There are six known cases of breeding, all in Colorado.

Horned Owl. 
This is the present recognized name for this variety instead 
of subarcticus (Stone., Am. Nat. XXXI. 1897, p. 236). To set- 
tle the exact name of the common Horned Owl of Colorado, 
Mr. C. E. Aiken lately sent eight specimens to the Smithsonian 
Institution. They embraced dark and paler examples from 
both the plains and mountain. They were pronounced by Mr. 
Ridgway as all of them pallescens, saying, “some of them are 
darker than the normal average style and incline toward satur- 
atMs^ in fact they may be fairly considered intermediate between 
the two, though still nearer pallescens than saturattisy

Two specimens shot near Colorado Springs and reported by 
Mr. Aiken represent about the extreme southern range of the 
species in Colorado.

Mr. Aiken adds three records to those previously published; 
one on the plains at Pueblo November i, 1871; one in the win-
