1907. Baring. — Mammals of Lambay. 23 



Introduced Species. 



One Fallow buck and two does were introduced from Portrane 

 by Count Considine about the year 1889. They also found a 

 congenial home, for although the known deaths number between 

 fifty and sixty, there is now on the island a herd of between 

 seventy-five and one hundred head, which shows no symptoms 

 of weakness or want of fertility. They giow remarkably thick 

 coats in winter. It is noteworthy that a considerable pio- 

 poition of the deer are black and without spots. According to 

 eye-witnesses, the three originally introduced were all of the red, 

 spotted variety. In the same category as the deer may be placed 

 one male and one female Moufflon. These were placed on the 

 island in 1906, and the surroundings seem to agree with them 

 well. 



Cetacea 



Porpoises have no special connection with Lambay, but are 

 occasionally seen from the shore, and on that account have been 

 included in the list. 



BIRDS, 



BY ROBERT PATTERSON, F.Z.S., M.R.I. A. 



The great attraction to the ornithologist undoubtedly lies in the 

 sea-birds of the island. 1 Owing to the comparative absence of 

 trees, the scarcity of hedges and marshes, and absence of running 

 water, the land-birds, as a whole are poorly represented, if not 

 in number of species, certainly in number of individuals. Leaving 

 the Rooks, Starlings, and Jackdaws, which are numerous 

 about the castle, out of the question, any one walking across 

 the high centre of the island from the harbour to Lambay Head 

 on a day in midsummer, would be able to make but a poor list of 

 the number of land-birds seen, if Lapwing, Meadow Pipit, and 

 Wheatear were eliminated. The common birds of the mainland, 

 such as Song Thrush, Tits, Chiff-chaff, Sedge Warbler, Reed
