MU. J. H. GURNEY ON BIRDS OF THE PEMBROKESHIRE ISLANDS. 631 
acres in extent, separated from St. David’s Head by a channel 
two miles in width, through which even in calm weather there 
runs a tremendous tide. It abounds with Rock Birds on its 
seaward side only, where every little bay has also its Grey Seal 
or two. 
In Bishop Gibson’s edition of Camden’s ‘ Britannia ’ (ed. 1772) 
there is an account of Ramsey, with some notice of its birds by the 
Rev. Nicholas Roberts, and especially of four kinds which bred 
there and on some adjoining islands (probably the North and South 
Bishop Rocks and ‘ The Clerks ’). The four species are : — 
The Mora (Guillemot). 
The Poethwy (Razorbill). 
The Pal (Puffin). 
The Harry-bird (Manx Shearwater). 
Shearwaters probably still breed on Ramsey in very small numbers, 
for my son picked up the remains of a dead one, and of the other 
three species there are plenty. 
The numerical strength of the birds breeding on Ramsey island 
may be roughly reckoned as follows : — 
Guillemot ... 4,000 
Bridled ... 16? 
Razorbill ... 800 
Puffin ... 150 
Shag 50 
Cormorant? ... 0 
Mathew says Cormorants are in 
Kittiwake ... 400 
Herring Gull ... 200 
Oyster-catcher ... 70 
Peregrine Falcon 
Buzzard ... 2 
Raven ... 2 
Chough ... 4 
Jackdaw ... 500 
Carrion Crow ... 4 ? 
Rock Dove ... 8? 
Stock Dove ... 12 
It is difficult to calculate any feathered population, but in the 
case of these Guillemots I was determined to arrive at a census of 
(I did not see any, but Mr. 
equal numbers with Shags).

(Perhaps not breeding).
