150. Strix flammea Z. Barn-Owl. 
Resident, generally distributed, fairly common; most 
numerous in South Yorkshire. In the latter months of the 
year there are instances of this species sometimes occurring 
in unusual numbers inland, and it is also occasionally 
observed on the coast as an autumn immigrant. 
Fam. BUBONIDE. 
151. Asio otus (Z.). Long-eared Owl. 
Resident in woodland districts, where it is local in its distri- 
bution but common where found. Is observed annually 
on the coast as an immigrant in late autumn, accompany- 
ing A. accipitrinus, and in the winter; and it is question- 
able if these immigrants do not replace the local birds, 
which appear to leave in the winter and return in early 
spring.
