The Birds of Pembrokeshire. xli. 
Pembrokeshire is deficient by no less than 132 of this number. No 
doubt, the small number of birds we can record for Pembrokeshire 
is due, in great part, to the want of observers who might have noted 
occurrences that are not included in any of the existing lists ; and 
we think, also, that the county is left out in the cold, so to speak, by 
many birds that either pass its coasts in their migrations, or do not 
extend their flight so far towards the south-west as to reach it ; and 
we have pointed out that the Precelly Mountains act as a barrier to 
exclude from it several of the smaller summer visitants. But we think 
it very probable that an ornithologist posted at a good position, such 
as at Pembroke, for instance, might have it in his power to make 
additions to our list. It will be observed that we have been able to 
set down only ¢wo stragglers from America. In whatever way 
American birds reach the British Islands, whether by crossing the 
Atlantic far to the north, where it is narrowest, and then striking 
and following down the coasts either on the east or west, or by coming 
chiefly overland v@ the north of Asia and Europe, the extended 
littoral of Pembrokeshire might have been expected to have inter- 
cepted as many American species as the coasts of North Devon and 
Cornwall ; and as, for those two counties, at least a dozen American 
birds have been recorded, some additions to the Pembrokeshire list 
might be fairly anticipated in this direction. 
Our 235 species on the Pembrokeshire list are composed of :
