 the fifth volume of Mr Audubon's Ornithological Biography. 



PERNIS APIVORA. BROWN BEE-HAAVK. Vol. Ill, p. 254. 



Dr Robertson, of Dunkeld, Perthshire, has favoured me 

 with the following notice : — " A very beautiful specimen of the 

 Honey Buzzard, Pernis apivorus, Cuv. Reg. Anim., was shot on 

 the Dalguise property, about four miles west of this, in the 

 autumn of 1836. It was shot in an open park, near the river, 

 in front of Dalguise House, and is in the possession of the 

 Honourable Mr Maule. I mention this particularly, as it is 

 the only instance known to me of this bird having been found 

 so far north. Its length is about 20 inches. The bill bluish- 

 black, the cere light yellow. The tarsi are well-feathered half 

 down. The feet, as well as the uncovered half of the tarsi, 

 yellow ; claws not much crooked. The upper plumage is of 

 an almost uniform dark brown, except on the head and upper 

 part of the neck, where the feathers are very short and very 

 thick-set, and of a light bluish colour. The lower part of the 

 plumage is white, and there are one or two dark feathers on 

 the breast. The tail is of a brownish cast, with dark bars, and 

 extends a little beyond the wings."

Mr Mackinnon informs me that this bird breeds on the Main 

 Island of St Kilda. He states that several pairs occur there ; 

 that the young have the upper parts grey all winter, and change 

 to white in summer ; that he has been at the nest of one ; and 

 that the old birds were so violent in their attacks that he had 

 difficulty in keeping them off with a stick.
