160 THE ZOOLOGIST. 



188], I climbed to the summit of a tabular-topped pinnacle at the 

 north-eastern end of this island — a difficult feat, which the Ravens 

 resented as an unwarrantable intrusion. This is probably a 

 favourite roosting-place, and they have bred on the cliffs below. 

 The Raven and the Peregrine are very jealous neighbours, and 

 are continually having battles on the border-ground of their 

 domains. Tn Donegal I have frequently seen one drive the other 

 away when trespassing. It is not usual to find them side by side 

 as at Lambay, yet I know a small isolated mountain in Galway 

 where both species breed in close proximity, with only the summit 

 between them, the Raven, as it should be, on the northern side, 

 and the Peregrine to the south. At Howth Ravens have reared 

 their young several times between 1870 and 1880; four were 

 taken about 1872 by my cousin, Mr. M'Dougall, who showed me 

 their nest of 1878. A pair used frequently to be seen about the 

 Baily Lighthouse, but within the last few years they are perhaps 

 deserting Howth for Lambay. In Co. Wicklow they still cling 

 to their old breeding-haunt at Lough Bray, and though often 

 banished, they are usually to be met with about Lugnaguilia. 

 They have been destroyed in places in this county by letting 

 clown " flams" to their nest and burning them out. It is believed 

 they attack lambs and tear out their eyes, but a herd who has 

 lived in their neighbourhood for sixty years " never knew them 

 to meddle with lambs, unless dead." The Raven breeds very 

 early ; I have seen the young flying strong in the second week of 

 May. It is said to breed on the Saltee Island, but I saw none 

 there this year. It is not infrequent in the mountainous districts 

 of the west and north of Ireland. 



Hooded Crow, C. comix, Linn. — Is included by Watters 

 amongst the birds breeding on the rocks at Lambay, but it has 

 not done so recently, and is now rarely, if ever, seen in this part 

 of Ireland. 



Rook, C.fmgilegus, Linn. — Is of frequent occurrence. 

 • Jackdaw, C. monedula, Linn. — Breeds on the cliffs on the 

 northern side. 



Cuckoo, Cuculus canorus, Linn. — A summer visitor. One or 

 two usually remain a short time, perhaps long enough to deposit 

 their eggs and leave. 



Nightjak, Cajjrimuhjus cuvojhcus, Linn. — I saw a Nightjar on 

 Lambay in May, 1882. A pair or two usually breed on Howth,
