October. Many pass the breeding-season in Morocco." — 
Favier. 
The Scops Owl is very plentiful^ both in Morocco and 
Andalucia, but is almost entirely migratory. I was much 
surprised to hear one on the 13th of January, 1872, near the 
Goto del Rey, and another nearer Seville on the 15th; but 
from what I afterwards heard at Seville, there is no doubt a 
few sometimes remain there during the winter ; I never heard 
them during that season at Gibraltar, the earliest date of 
the vernal migration noticed being the 4th of March, the first 
nest being on the 4th of May. This Owl always nests in 
holes of trees. I do not know of any instance of its nesting 
in rocks or ruins, like Carine noctua, which nests by preference 
in those places. 
Abundant in the cork-wood ; the nest is easily discovered 
by going round and hammering at the old cork-trees with a 
stick, when, if a Scops Owl flies out, ten to one there is a nest. 
They are strictly arboreal ; and their monotonous single note 
may be frequently heard repeated at regular intervals by day 
as well as by night. They frequent trees in the midst of 
towns, and may often be heard in the trees which fringe the 
Delicias, the drive and Rotten Row of Seville. 
They chiefly feed on coleoptera, and, I believe, are almost 
entirely insectivorous. 
The irides, like those of most of the Tufted Owls, are yellow.

This Owl is not included in Favier's notes on the birds of 
Tangier, though it is, no doubt, found in the mountainous 
districts of Morocco ; indeed I heard of a large Owl about 
Tetuan, but could not obtain a specimen. 
It is resident in all rocky localities in Andalucia ; and some 
frequent the " Rock," probably nesting in some of the nume- 
rous inaccessible caverns of the east side. One was caught in 
1869 in a magazine near the Rock gun; having gone down into 
the narrow space between the outer aud the main wall of the 
magazine, it was unable to rise. I had this bird alive for
