Breeds on precipitous coasts ; common at sea all round the coast, especially

237.— BLACK GUILLEMOT. Uria grylle grylle (L.). 



Rare visitor to the coast ; formerly bred on the Orme's Heads and off

In regard to the occurrence of the Black Guillemot on the 

 Orme's Head, mentioned in the Fauna, it is worthy of note that 

 Pennant alludes to it on the Great Orme {Tour, III., 149), but 

 WiUiams and Price refer to it on the Little Orme. Mr. Coward 

 {Vert. Fauna Cheshire, I., 438) mentions a water-colour sketch 

 of an immature bird in the possession of the late Capt. Congreve, 

 marked " Burton, 1837." This place is on the Dee estuary.

 during gales in winter. 



Mr. R. J. Ellis had one brought in by his cat at Abergele, 4th 

 February, 1908. Mr. R. W. Jones records one at Llandudno, 

 2nd February, 1912. At that time there was a remarkable 

 irruption of Little Auks into Britain, mainly on the east coast. 

 In August, 1911, Mr. H. G. Attlee found the remains of one at 

 Mochras.
