For fifty-eight 3'ears from this date he resided at Moyview. 

 giving all the time that his pre-occupation as a busy farmer 

 allowed to his much-loved held pursuits. In 1875 he made 

 the unexpected addition (for so westerly a station) of the 

 Pied Flycatcher to the list of Irish birds ; and it was chiefly 

 due to his vigilance that the Spotted Redshank and the 

 Glaucous and Iceland Gulls were ascertained to visit Ireland 

 with nnich greater frequency than had been supposed. In 

 knowledge of the habits of shore-birds generally, he acquired 

 a proficiency far ahead of most of his lirother-naturalists. and 

 A. G. More deservedly wrote of him to a correspondent (in 

 1893) : '' Mr. Warren knows the Gulls better than any one 

 else in Ireland." He frequently undertook exploring ex- 

 peditions through different parts of the western provinces, 

 and reported results to the Royal Irish Academy, besides 

 contributing many notes (chiefly on birds) to scientific 

 journals. 



When the decision to bring out a new standard Mork on 

 Irish birds was arrived at in 1890, it was proposed that the 

 four leading ornithologists of Ireland should be entrusted 

 with its preparation ; but the withdrawal of two through 

 More's death and Barrington's election to proceed indepen- 

 dently Avith his Migration inquiry, left the actual responsilnlity 

 to Ussher and Warren, whose names a})]iear on the title-page 

 as joint authors of the book. As is well known, the writing 

 of 71m Bird'^ of Ireland was almost wholly the work of 

 R. J. Ussher, Warren contributing only the cha])tcrs on the 

 White Wagtail, Surf Scoter, Spotted Redshank, Greenshank. 

 Bar-tailed Godwit, and Sandwich Tern. But it is imnecessarv 

 to say that the amount of material contributed by Warren 

 in the voluminous notes he placed at his friend's disposal 

 was such as amply to justify the retention of his nauie as 

 joint author. 



As one who had contributed so largely to both the standanl 

 works on Irish birds — works separated liy an interval of half 

 a century — Warren occupied a uni(|ue ])osition auiong the 

 naturalists of his native country, and his friendshi]) was much 

 prized by all who possessed it. His robust constitution and 

 active outdoor habits kept him to an advanced age in full 

 possession of the health and strength that he had enjoyed 

 since boyhood, and when well over seventy he would still walk 

 for miles with a rapidity that sometimes taxed the energies 

 of comparatively young com pan ions. His conveisation
