The Irish Naturalists 
March, 
The story of his hfe for the next fifty -eight years is 
inseparably bound up with the birds of Killala Bay and of 
the surrounding country. Correspondence with Thompson 
continued briskly up to the date of that naturalist's death, 
early in 1852. Though the third and last volume on the 
Birds of Ireland was already out in the spring of 185 1, so 
that all letters on the ornithology of the West were too late 
to be of use for that work, Thompson continued to take the 
deepest interest in all that he could collect on the subject. 
More than once he mentions having read and made 
many extracts from letters shown him by Warren's cousin 
and close friend, Alexander Taylor, another great lover of 
birds. In the case of a letter relating to the White -tailed 
Eagle shot at Bartragh in December, 185 1, Thompson 
states that he has copied nearly the whole. Fishes as well 
as birds were sometimes discussed. Almost every branch 
of natural history had some attraction for Warren, and 
when returning from distant expeditions he brought 
home specimens of many forms of marine life — particularly 
among the mollusca, these being the subject to which his 
sister. Miss Amy Warren, has, as is well known, long devoted 
special attention. 
About 1862 he began contributing notes to the Proceed- 
ings of the Dublin Natural History Society. Some of his 
■ papers weie read for him in his absence ; but one which he 
read in person on the 2nd of February, 1866, on rare bird 
visitors to the Moy and to Killala Bay, had an important 
effect in leading to the formation of his friendship with A. 
G. More. Among the birds dealt with was the Fulmar 
Petrel — at that time only known to Irish naturalists on 
the strength of dead specimens picked up along certain parts 
of the coast. Warren's remarks as to the comparative 
frequency of such occurrences on the Connaught coast, and 
the absence of any records from Donegal or Derry interested 
More, who volunteered an explanation. From this time 
onward the friendship between the two steadily grew, and 
the cementing of other ornithological friendships — including 
those with Ussher, Barrington, and Howard Saunders — 
was much promoted.
