LIFE HISTORIES OF NORTH AMERICAN DIVING BIRDS. 95 



agreeable pets only that they emitted an unpleasant grunting noise, 

 and ran about incessantly during the night, when eadh footstep 

 could be counted." 



Their relations with other species are at times playful or warlike, 

 depending on the point of view. Thus I once watched a puffin chase 

 three black guillemots by repeatedly diving and swimming under 

 water toward them while they followed the same tactics in eluding 

 the pursuit. At last all four came to the surface near together, the 

 ardor of the chase evaporated, and they all seemed unconscious of 

 each other's presence. 



Winter. — The full migration of the puffin along the New England 

 coast takes place in October or later. During the winter they fre- 

 quent by preference the waters off rocky headlands, like Cape Ann 

 or Marblehead, and may best be observed at such places, or in winter 

 steamboat trips along the coast. Their food habits at this season are 

 much the same as in more northern waters already described. 



DISTRIBUTION. 



Breeding range. — Coasts and islands of the North Atlantic. For- 

 merly from Maine and the Bay of Funcly, Newfoundland, the Gulf 

 of St. Lawrence, and Labrador north to southern Greenland. Now 

 restricted on the coast of Maine to Matinicus Rock and Machias Seal 

 Island ; and in the Gulf of St. Lawrence to Bryon Island, Bird Eock, 

 Anticosti, Bald Island, and Bradore. Probably extirpated from the 

 remainder of the above range south of northern Labrador. Some 

 Greenland records probably refer to F. a. naumamii but arctica has 

 been taken at Holsteinborg (and elsewhere?). 



In Europe breeds from Berlenga Islands, off Portugal, north to 

 Norway, the British Isles (mainland of Great Britain, Ireland, 

 Scilly Islands, Outer Hebrides, Orkney, and Shetland Islands), the 

 Faroes and Iceland. 



Winter range. — Birds probably winter as far north as they find 

 open water, but there is little definite information on this point. 

 They occur along the coast of Maine south to Massachusetts, rarely 

 to Long Island, New York, and casually to the Delaware River (near 

 Chester, Pennsylvania). Audubon recorded it from the mouth of 

 Savannah River. 



They also winter about the coast of Great Britain and south to the 

 western Mediterranean Sea (Spain, east coast, Italy, Sicily, Malta, 

 and the coast of Morocco), casually to the Azores and Canary 

 Islands. 



Spring migration. — Migration dates are almost wholly lacking. A 

 bird was taken on Long Island, New York, March 30 (one found 

 April 30 was badly decayed and may have died weeks previously).
