Asio otus. The Long-eared Owl. 
A bird o£ passage, but by no means common, and so far 
only noticed in the autumn. L. has one in his collection and 
has shot four of them—one in the autumn of each of the 
following years, 1893, 1899, 1900, 1904. Bearing in mind 
how seldom even our common residential owls are seen, the 
fact of this species having been observed on four occasions in 
twenty-seven years, whilst passing through the island on 
migration, argues that it is of frequent occurrence as a bird 
of passage, and is probably a regular visitor. It is curious 
how seldom this bird is noticed during the spring migration. 
It usually occurs here in November, so it would appear to be 
a late migrant at this period. I have not myself seen this 
bird. 
Asio accipitrinns. The Short-eared Owl. 
A common bird of passage and also a winter visitor, but 
the numbers remaining for the winter months vary consider¬ 
ably in different years. As a bird of passage it occurs more 
frequently in the autumn than the spring. L. tells me he 
once shot a specimen here in August. 
Circus seruginosus. The Marsh-Harrier. 
L. has two in his collection—a male and a female. He 
shot the male on the 21 st of August, 1899, and the female 
the following day. 
Mr. A. C. Tourgis also had a young male in his collection. 
He shot it here about the year 1894. 
Circus pygargus. Montagu's Harrier. 
Mr. Cecil Smith says of this bird : “ Miss C. B. Carey 
records one in the 4 Zoologist' for 1873 as having been shot 
in Alderney in July of that year. She adds that it was an 
adult male in full plumage, and that she saw it herelf at 
Mr. Couch’s shop.” 
The above is the only record I have for this bird. 
Buteo buteo. The Buzzard. 
L. tells me he shot one in the autumn of 1886. 
The only other record for the occurrence of this bird in
