A PRACTICAL HAXDBOOK OF BRITISH BIRDS. 



(Evans) ; 28-30 days (Nelson) 

 brooded. 



32 days (Paynter). Single 



Pood. — Chiefly small fish, such as sand-eels (Ammodytes tobianus), 

 but information scanty ; occasionally smaller Crustacea and 

 mollusca. 



Distribution. — British Isles.— Resident. Breeds suitable cliffs. 

 More plentiful than Razorbill, except in Ireland. Fairly generally 

 distributed in seas autumn and winter (scarce Irish seas winter), 

 and frequently washed up on coasts and occasionally storm-driven 

 inland. Birds breeding in Orkneys and Shetlands and probably 

 St. Kilda (? other Outer Hebrides) appear to be of the northern 

 form. 



Distribution. — Abroad. — Probably this form formerly breeding 

 Alderney, at least 1903 on Sark, south to north-west coast 

 Prance and Berlengas Is. (off Lisbon) but no breeding birds from 

 these localities have been examined.
