The Irish Naturalist. 



April, 



Cranes, and Bustards have been liberated, but have either 

 left us or failed to establish themselves. In 1909 some 

 Chough's eggs were put in two Jackdaws' nests. One of 

 the nests was destroyed by a Puffin. In the other one 

 bird was hatched, but did not survive. Sand-martins have 

 been seen on passage. A young male Montagu's Harrier 

 met death by misadventure in August, 1909. A Carrion 

 Crow, as already recorded was seen here in 19 13, and in 

 1910 and 191 1 a Magpie spent some months on the island, 

 but does not appear to have nested. Dippers have not 

 been seen again. 



The Moufflons now number over a dozen. A male 

 Chamois has been on the island since March, 1910 ; un- 

 fortunately it has been found impossible to procure a mate 

 for him. The Brown Hare (Lepus timidus) has bred 

 steadily since 1910, but without any considerable increase 

 in numbers. 



A new mammal can be added to Lambay's list in the 

 shape of the Hairy-armed Bat {Nyctalus Leisleri, Kuhl.), 

 of which species an individual was caught in August, 1913. 

 The Whiskered Bat (Vespertilio mystacinus) is already 

 recorded from Lambay, on the strength of a single specimen 

 caught in 1905 but not preserved. Assuming the latter 

 identification to be correct, it is noteworthy that the two 

 species should make their home in Lambay. The one 

 recorded in 1905 was caught in a tired-out state, in broad 

 daylight, and may possibly have been a straggler from 

 other regions ; whereas the Hairy-armed Bat was taken, 

 with another, out of his breeding place in a tree, and is 

 undoubtedly indigenous. On the other hand, the claim 

 of the Long -tailed Field-mouse (Mus sylvaticus) to be 

 considered a Lambay mammal seems to me doubtful ; 

 it rests on a single specimen caught by me in 1905, which 

 at the time I took to be a House-mouse. No Field-mouse 

 has ever been seen on Lambay since, although we have 

 kept our eyes open for him and even set a small price on 

 his head. The grass-mice " which we come across when 

 mowing the meadows have always turned out to be House- 

 mice.
