ZOOLOGY. 



Bewick's 5wan in Co. Down. 



On 9th December, 1919, I saw a Bewick's Swan, Cygnits hewicki, and 

 two cygnets on a large pond known as McKee's Dam, about a mile outside 

 Hillsborough. These birds were very tame, and I was able to go fairly 

 near them without disturbing them. Quite close to them a pair of Mute 

 Swans and their cygnets were feeding, so there was an interesting oppor- 

 tunity for noticing the differences between the two species. The smaller 

 size of the liewick's Swan was evident, and its neck lacked the graceful 

 curve which adds so much to the beauty of the Mute Swan. Its bill 

 appeared to be quite black, the yellow marking not being visible in the 

 bad light. The cygnets were much smaller and greyer than the Mute 

 cygnets, and their necks were almost straight like that of their parent. 

 On the afternoon of the same day Mr. C. B. Horsbrugh went with me 

 to the pond. Wo brought with us a pair of field glasses, and by their aid 

 were able to examine in detail the markings on the bill of the adult bird, 

 and noted that the yellow basal patch cHd not extend so far down the 

 bill as the nostrils.
