516 Recently published Ornithological Works, 



known to inhabit the island, with their native names, their 

 status, and a special paragraph about their food as deduced 

 from the study of the stomach-contents; about 2200 stomachs 

 were collected and investigated. A coloured plate by Mr. 

 Fuertes of Todus americanm, one of the most characteristic 

 birds of the island, forms a fitting frontispiece to tliis

Witherby on Bird-marking. 



[The "British Birds" Marking scheme. Progress for 1915 and some 

 results. By H. F. Witherby. 'British Birds,' London, ix. 1916, 

 pp. 222-229.] 



As would naturally be expected, the progress of the 

 ' British Birds ' marking scheme has been considerably 

 handicapped by the war. The total number of birds ringed 

 in 1915 is 7767 as against 13,024 in the previous year, but, 

 considering the times, this must be regarded as quite satis- 

 factory. 



Among interesting recoveries reported are the following : — 

 A Redstart ringed in Westmorland in June was recovered 

 the following October in Portugal. Swallows ringed in 

 June and August 1914 in Staffordshire and near Birmingham 

 were recovered in May 1915, at the same places where they 

 were ringed. This has also occurred in the case of a Martin, 

 a Sand-Martin, and a Wryneck, showing how individual 

 birds return to the spot where they were bred. There are 

 many other interesting results recorded, and we must con- 

 gratulate Mr. Witherby on his continued success in carrying 

 on this most useful and valuable work. 



Cassinia. 



['Ca^sinia.' A Bird Annual. Proceedings of the Delaware Valley 

 Ornithological Club of Philadelphia for 1915. Publ. March 1916.] 



As usual, 'Cassinia' contains a number of scholarly and 

 well-written articles, of which the most interesting to 

 European readers is undoubtedly that on Titian Ramsey 

 Peale by Mr. Witmer Stone. 



Titian Peale was the fourth and youngest son of Charles
