Thi.s bird is said to be an occasional visitor to the Bermudas ; but its occiu'rence 

 there must be very rare, and due to accidental circumstances ; and its chiim to be 

 received into the Nortli American fauna appears to me to be very doubtful. The 

 first published mention of Uulwer's Tetrel was made l)y Selby and Jardine, in the 

 second volume of their Illustrations ; and it was there described from specimens pro- 

 ciu'cd by Mr. Bulwer, a gentleman who had been living for several years in j\ladeira, 

 wliere this bird was ascertained to be resident during its breeding-season, (diiefly on 

 tlic small adjacent islets. 



Dr. Scldegel also claims to possess an example of this Petrel procured in Green- 

 land. Gould, in the twenty-second number of liis "liritisli IJirds," mentions a single 

 instance of its occurrence in England ; tins was on the banks of the Tire, near Tan- 

 fichl, in Yorkshire, May 8, 1837, where a specimen of this bird was found which liad 

 boen dead but a short time ; and Mr. Dresser records another, taken off Scarborough 

 in tlie spring of 1849. 



It is not known to breed elsewhere than in the Canaries and iMadeira. Moquin- 

 Tandon speaks of it as very common on the small Island of Alegranza, where it 

 breeds in the holes in the rocks. It has a cry resembling that of a puppy, from 

 wliicli it receives the local name of Perrito. Mr. Godman ("Ibis," 187L*) mentions 

 iiuding it breeding in considerable numbers on the small Island of Deserta. It was 

 nocturnal in its liabits, and was not seen flying about in the daytime, althongli tliere 

 were plenty of a smaller species. The nests were low down at the foot of tlie clift's, 

 un<ler the fallen rocks, where the birds were easily caught with the hand while 

 sitting on their eggs. 



Dr. Heineken (" Edinburgh Journal of Science," October, 1829) refe- , probably to 

 this Petrel as found on the uninhabited islands near Jladeira and Porto Santo. He 

 states that it first a}ipears in February and March, begins to lay in June, hatcdies 

 out its young in July, and that none are seen after September until tlie following 

 spring. It is never seen in flocks, nor in the Bay, but keejjs out to sea, and is in 

 a great measure nocturnal in its liabits.
