IV. 
HEADS OF RINGED GUILLEMOT, 
COMMON GUILLEMOT, AND YOUNG RAZORBILL. 
The head of the Ringed or Bridled Guillemot was drawn from one shot on 1 8th 
April, 1861, on the Clyde at Greenock, by Mr. John Kerr of that town, who states 
that among a number of Guillemots shot at the time this was the only Ringed 
Specimen. On the 13th May of the same year we were sufficiently near to one 
in Loch Ailort to ascertain that it was of this species. 
The next head is that of a Common Guillemot in winter plumage from a fresh 
specimen in Glasgow Market in January. 
The third head is that of a Razorbill bought in Glasgow Market in January. 
It is a bird of the year, and therefore the beak is not fully developed, but the 
plumage resembles the winter plumage of the adult bird. 
Razorbills and Guillemots are common in Loch-na-Nuagh all Summer, but we 
have not found that they breed there. There are also generally a few Puffins. 
The Guillemot flies much better than the small size of the wing indicates. 
We often see them take long flights, when changing their fishing-ground, in a flock, 
hut have never known one rise from the water to escape. When pursued they 
(and also the Razorbills and Puffins) invariably dive. 
We once had an excellent opportunity of observing the way in which the 
Guillemot uses its wings under water by letting away, in clear and not deep 
water, one which had been captured uninjured.
