TINKLER: THE AVI-FAUNA OF ARKENGARTHDALE, ETC. 323 
doubt having been expressed in Messrs. Clarke and Roebuck’s 
Handbook as to the occurrence of this species in Swaledale, 
I have taken particular pains to settle the matter, with the 
result that I am in a position to positively assert that the only 
two species of wild dove occurring in this district are the ring 
and stock doves. The notion that C. /ivia occurs has arisen 
from the stock dove being invariably called by the keepers, and 
dalesmen generally, either rock dove or else blue roc 
Phasianus colchicus. Pheasant, Resident in hall numbers 
in the woods about Ellerton and Marske. Not known in 
Arkengarthdale or Upper Swaledale. 
Perdix cinerea. Partridge. Resident in the valleys and up to 
the edge of the moors, but not abundant. More numerous in 
Lower Swaledale. 
Lagopus scoticus. Red Grouse. Local name, Moor Game. 
Found in great abundance on all the moors. In very severe 
winters they sometimes gather into large flocks and come down 
into the valleys in search of food, and many for a time leave the 
district altogether. In 1885 a nest was found on Routh Head, 
in Arkengarthdale, containing seventeen eggs. 
Tetrao tetrix. Black Grouse. A very local resident, being 
almost confined to Kexwith in the New Forest, where a few pairs 
breed yearly, and I believe their numbers are increasing steadily. 
An attempt to introduce them into Upper Swaledale some years 
ago, failed. In 1883 a pair nested on Hurst Moor. 
Rallus aquaticus. Water Rail. Occasionally seen along the 
banks of the Swale. I have never seen it in Arkengarthdale. 
Porzana maruetta. Spotted Crake. A male was found dead 
near Ellerton, in September 1858. 
Crex pratensis. Corncrake. Local name, Daker Hen. 
A common summer visitor to the valleys, arriving about the end 
of April. 
Gallinula chloropus. Moorhen. Occasionally seen by the 
Swale. In 18go0 one was seen by the Arkle, near Scar House. 
Fulica atra. Coot. Has been seen on Moss Dam, in Swaledale, 
but is very rarely observed in this district, there being so few 
places suited to its habits. 
Charadrius pluvialis, Golden Plover. An abundant resident 
upon the moors, breeding regularly upon them throughout the 
district. About the end of July, old and young gather into 
large flocks and come down into the meadows and pastures for - 
a time, before taking their departure to the coast for the winter. 
They return again in March. Although thus deserted by our 
Nov. 1892.
