Aquila. 



[Aquila : Periodical of Ornithology. Edited hy Steplian vou Clieruel. 

 Vols. xxvi. & xxvii. Budapest, 1920 & 1921.] 



The articles iu 'Aquila^ are printed in Magyar and 

 German with occasionally a snmmary in French or English. 

 The first one of vol. xxvi. by the editor, Herr von Chernel, 

 is a plea for a renewal of an international scheme for the 

 protection of birds useful in agriculture. Tt was prepared 

 for the great Peace Conference in Paris at the end of the 

 war, but apparently nothing came of it. Bird-ringing was 

 continued actively during the war years in Hungary, and 

 J. Schenk has a report on the results for the years 1916- 

 1919. Some 2500 birds were ringed, the greater number 

 being Swallows (701), Great Tits (597), and Storks (241). 

 Two of these latter, ringed in the summer of 1911, were 

 recovered in Egypt in 1912 and in South Africa in 1916 

 respectively, but all the Tits recovered were taken in the 

 same locality in which they were ringed, as were also the 

 Swallows. 



Other articles by J. Schenk deal with migration dates in 

 Hungary for 1919 and 1920 respectively. The food-habits 

 of the Magpie are reported on at great length by E. Csiki, 

 but the results are not presented very clearly, so that it is 

 difficult to say whether the bird should be considered useful 

 or harmful in Hungary. The longest article in the 

 27th volume is one on the Birds of the Siebenbiirgen in 

 Transylvania, based on a manuscript written by INicolaus 

 V. Zeyk, who lived in the early half of the 19th century. 



There are a number of shorter notices all relating to 

 Hungarian ornithology in the two volumes here noticed. 



British Birds.

 in the British List. Vol. xiv. June 1920 to May 1921 ; 12 nos.] 



The last completed volume of ' British Birds ' fully main- 

 tains the high standard set up by its predecessors, and is 

 full of matter of interest to students of Palijearctic birds.
