APPENDIX. BIRDS. r 415 



many as seven or eight specimens were procured at one shot, on 

 the Deveron. I have seen as many as live or six together. 



PODICEPS CRISTATUS [Great Crested Grebe]. An occasional visitor. 



PODICEPS RUBRICOLLIS [Rednecked Grebe], 



Of more frequent occurrence, but generally in immature plumage. 



PODICEPS AURITUS [Eared Grebe]. Less frequent than the last. 



PODICEPS MINOR [Little Grebe]. 



A winter seldom passes without an opportunity occurring to 

 obtain this species. It is one of the most expert divers we have. 



COLYMBUS GLACIALIS [Great Northern Diver]. 



Some seasons pretty plentiful. Splendid specimens are at times 

 procured, but they are generally immature. 



COLYMBUS ARCTICUS [Blackthroated Diver], and 



COLYMBUS SEPTENTRIONALIS [Redthroated Diver]. 



Winter visitors, in about equal numbers. A few of them gradually 

 fall victims every spring to getting entangled in the bag-nets 

 set for salmon. They not unfrequently visit our larger streams, 

 where they make great havoc among the smaller of the finny 

 tribe. 



URIA BRUNNICHII [Brunnicfts Guillemot] has been once met with. 

 URIA TROILE [Common Guillemot], 

 URIA LACHRYMANS [Ringed Guillemot], 

 URIA GRYLLE [Black Guillemot], 

 MORMON FRATERCULA [Puffin], and 



ALCA TORDA [Razorbill]. 



All these species breed with us, but the black guillemot only 

 rarely. I have procured several ringed guillemots both in 

 winter and summer ; I have also been shown places in the cliffs 

 where the fishermen say they breed. 



ALCA ALLE [Little Auk]. 



A winter visitor. In December 1846 a terrific sea-storm raged 

 here for the greater part of the month ; at its termination I 

 counted between the Burn of Boyne and Greensicle of Gamrie, 

 a distance of about nine miles, nearly sixty of these little birds 

 lying dead, besides a number of guillemots and razorbills. 

 Great numbers were also found dead in the fields throughout 

 the county. 



CARBO CORMORANUS [Cormorant]. 



Frequent, except for a short time during summer. A pair or two 

 may breed with us, but that is all. Like the divers, they 

 destroy great numbers of fish. 



CARBO CUISTATUS [Shag]. 



Only, I believe, an occasional visitor.
