Porpoise (Phoccena comTnunis). Common the year 



ronncl. 



AVES. 



ACCIPITRES. 



Fam. Falconidce. 



White - tailed Eagle (Haliaetus alhicilla). Is 

 said to have bred in Rousay in former years, and to 

 have destroyed numbers of sheep when these were 

 of the small Orkney breed: they are now only 

 occasionally seen. One is in the i^ossession of Gen. 

 Burroughs, a bird of the year. 



Peregrine Falcon (Falco ijeregrinus). Seen 

 throughout the year, though I could not hear that 

 they bred on the island. A pair frequented the 

 highest part of the cliffs for some time, but appa-

Merlin (Falco cesalon). Resident, a few pairs 

 breeding through the hill. They are very abundant 

 in autumn and winter, especially the former season, 

 haunting the garden late in the evening after the 

 small birds that come to roost there. 



Kestrel (Tinnunculus alaudarlus). Resident and 

 fairly common, a few pairs breeding in the sea-cliffs. 

 They are rather rarer in the winter than in the 

 spring and summer. 



Common Buzzard (Buteo vuJcjaris). One seen on 

 2nd November. Probably occurs regularly at the 

 migration time. 



Rough - LEGGED Buzzard (Archibuteo lagojDus), 

 Occurs probably every year during the time of 

 migration. I saw one hovering over the hill on 

 1st November, and two are in possession of Gen. 

 Burroughs at Trambland House. 



Hen Harrier (Circus cyaneusj. Much rarer than 

 formerly owing to constant persecution, though a 

 l^air or two still breed. The keejier shot the male 

 from the only nest he found this year, the hen, 

 strange to say, never coming near. It is far from 

 common in my experience to get the male from the
