38. Howard on British Warblers. 



[The British Warblers. A History with Problems of their Lives. 

 By H. Elliot Howard. Part 6. London, 1911 : R. H. Porter.] 



This part of Mr. Howard's work contains the Willow-, 

 R-nfous, and Savi's Warblers. The life-history of the first 

 of these is so similar to that of the ChifFchaff that it needs 

 no further comment, except that the author adduces an 

 instance of apparent polygamy which came under his 

 observation. The Rufous Warbler, being a casual visitor, 

 is, as usunl, merely described ; but a trip to Hungary has 

 enabled INIr. Howard to give us some valuable information 

 on the habits of Savi's Warbler, while he is inclined to 

 attribute to it that struggle for a breeding territory which 

 is the key-note in his account of every species. 



The photogravures are consistently charming, but we 

 are unable to comment on the coloured plates, as they have 

 been postponed, owing to an unfortunate accident.

[The L-ish Naturalist. .\ Monthly Journal of General Irish Natural 

 History. Sept. 1911-Feb. 1912. Dublin : Eason & Sous.] 



Though there is much of interest in these numbers of 

 our contemporary, little of it refers to Birds, and perhaps 

 the only item that w^e need mention is the report by 

 ]Mr. R. IVI. Barrington of the introduction of the Marsh- 

 Titmouse and the Nuthatch into Co. Tipperary, given as a 

 warning of their alien origin to those who may meet with 

 either species. The same writer tells us that he has just 

 issued a general index to the work, which may now be 

 obtained through the publishers.
