44 FAUNA OF NORTH WALES 



105.— HEN HARRIER. Circus cyaneus (L.). 



Former resident ; now very rare ; occurs chiefly on moorlands. 



Mr. P. F. Howden watched a pair at the nest in Cwm Bychan, 

 11 -12th April, 1909 : there were no eggs, however. I was 

 shown an immature male which had been obtained at Llan- 

 brynmair, Montgomeryshire, 11th November, 1907. 



106.— MONTAGU'S HARRIER. Circus pygargus (L.). 



Summer migrant, very rare : only known to have occurred in Carnarvon, 

 Denbigh and Merioneth. 



Mr. C. Oldham tells me that for several years past a pair have 

 frequented a certain mountain in Carnarvonshire, and no doubt 

 nested there. 



107.— COMIMON BUZZARD. Bnteo buteo buteo (L.). 



Not uncommon resident in the west ; autumn visitor to the east ; almost 

 unknown in Anglesey. 



By a most unfortunate blunder in typing the original Fauna 

 I am made to say on page 222, that the Buzzard rears two 

 broods in a season ! What I actually wrote was : — " The 

 Buzzard never rears two broods in a year, but like most birds 

 will lay again if robbed of its first clutch of eggs." This last 

 statement is correct, for I have known instances of second 

 laying, though such cases are not common. It would be more 

 accurate to state that the Buzzard sometimes lays again when 

 robbed of its first clutch. Another statement on the same 

 page which needs modification is that regarding the length 

 of time the young remain in the nest. It is given there as a 

 month. They stay a good deal longer than that, generally 

 about six weeks, before quitting the nest. 



Two instances of early nesting have been reported to me : 

 a nest with three young was found at Aber, 7th May, 1909, 

 by Mr. H. King ; while in 1913 Mr. T. Owen visited a nest 

 which contained three eggs on 16th April. With regard to 

 food ; a friend of Professor Salter's saw a Buzzard rise from a 

 cliff -slope near Barmouth with a snake dangling from its claws. 

 Dr. R. Newstead found remams of a Grouse in the stomach 

 of one obtained on Arennig, 9th September, 1902 : doubtless 

 the Grouse had been wounded during a shoot over these moors. 



108.— ROUGH-LEGGED BUZZARD. Biiteo lagopus 

 lagopus (Briinn.). 



Autumn and winter migrant ; rare in the east, still rarer in the west. 

 A pair were shot at Rhiwlas near Bala in 1866.
