Irish Naturalist. 



[The Irish Naturalist : A monthly Journal of General Irish Natural 

 History. Vol. xxx. for 1921 ; 12 nos.] 



We very much regret to learn that the ' Irish Naturalist^ 

 has reached a critical stage of its existence, and that unless 

 it receives further support it will be impossible to continue 

 its publication. It is to be hoped that means will be found 

 to carry it on even at a loss. It is the only magazine of the 

 sort dealing with Irish Natural History, and it would be a 

 great misfortune if it Ijecame extinct. 



The volume for 1921 contains very little ornithological 

 matter, except two articles by Mr. J. P. Burkitt on the 

 relation of song to the nesting-birds and some additional 

 comments by Messrs. D. C. Campbell and N. H. Foster. 

 Mr. Burkitt's theme appears to be that song is at its best 

 before the actual mating period, and that mating seems to 

 put a brake or stopper on song ; and that we should have 

 comparatively little song later in the year were it not for 

 unraated males and the recrudescence of song when there 

 are second broods. He also comments on the absence or 

 scarcity of autumnal or winter song in the north of Ireland 

 as compared with what is described as taking place in south- 

 eastern England during those months. The two articles are 

 interesting reading and should be studied by all interested 

 in Bird Psychology. The only other article on birds in the 

 present volume is one by Mr. R. F. Buttledge containing 

 some notes on birds in Mayo and Galway.
