BIRDS. 
Series SCHIZOGNATH, 
Order 1. COLUMBZ. 
Fam. COLUMBIDE. 
245. Columba palumbus Z. Ring-Dove. 
Resident, generally distributed, abundant. Flocks of immt- 
grants appear in October and November, their numbers 
being dependent on the severity, or otherwise, of the 
season. 
246. Columba livia Aoznat. Rock-Dove. 
Resident, very local, but numerous where it occurs. Breeds 
in considerable numbers in the Flamborough range of 
cliffs. They are also reported to breed in several inland 
localities, as near Sheffield, where they are entirely absent 
in winter, near Masham, near Pateley Bridge, and near 
Richmond. 
247. Columba cenas Z. Stock-Dove. 
Resident, local, but common in most localities where it 
occurs. This species is steadily increasing in numbers, 
and gradually diffusing itself over the county, being now 
frequent in localities where even ten years ago it was un- 
known. Mr. Allis (1844) stated that the only Yorkshire 
specimen he had seen was one in the York Museum, and 
that the only locality in which it was known to occur at 
that date was Sheffield, where they were reported as not 
unfrequent. Now the stock-dove breeds in all parts of the 
county, in localities too numerous to mention, but is least 
frequent in the north-west. At Flamborough it breeds 
plentifully in the sea-cliffs. 
248. Turtur communis Sey. Turtle Dove. 
Summer visitant, extremely local, and in very limited num- 
bers. Breeds annually in Holderness and near Sheffield. 
A few are observed in Eastern Yorkshire during the 
autumnal migration. It is less frequent in the spring, but 
on April 15, 1878, fifteen were observed at Flamborough. 
In Western Yorkshire it is quite of exceptional occurrence.
