X. and XL Jahres-harichte (1910 and 1911) der Vogelwarte 

 Rossitten. J. Thienemann. Journal fur Ornithologie, 

 1911, pp. 621-707, and 1912, pp. 133-243, 431-470; 

 and Sonderheft, 1913. 



The reports of the Rossitten station are increasing in bulk, 

 and each of the two latest reports l3^ing before us is sub- 

 divided into two parts. The first part of the 1910 report 

 contains the usual classified summary of the year's local 

 observations. Some idea of the magnitude of the migration 

 phenomena at Rossitten may be gathered from the fact 

 that the most extraordinary " rush " the present writer 

 (re-visiting Rossitten in that season) has ever seen, is dis- 

 missed with the words, " 3. Oktober : Starker Krahenzug " I 

 The second part concludes with an elaborate summary of 

 records of Woodcock-migration in East Prussia, West Prussia, 

 and Posen in the autumns of 1909 and 1910 (also issued 

 separately). The rest of Part II. consists of marking-records. 

 The most important of these is the summary of the Stork- 

 records (with maps), but this was published earlier as a 

 sej^arate paper, and has already been noticed here (Vol. IV., 

 p. 357). Other interesting records are those of a Black- 

 headed Gull marked as a nestling at Rossitten July 16th, 

 1908, and recovered as a breeding bird in Russian Kurland 

 (150 km. distant), May 16th, 1910 ; and of Spoonbills marked 

 in Holland and recovered res]:>ectivel3^ at the mouth of the 

 Seine and at St. Puy in southern France, the latter at the 

 beginning of August in the summer of marking. 



The first part of the 1911 report contains instead of the 

 usual classified summary of records, a journal of observations 

 kept at the little observation-hut at Ulmenhorst, near 

 Rossitten, during the best of the spring and autumn 

 movements. The account is interesting, and meteorological 

 data are added. A few pages of South German records 

 contributed by a Heidelberg correspondent are valuable 

 for comparison. 



Part II. contains many interesting marking-records. The 

 new Stork recoveries include cases from the Mbomu-Ubangi 

 basin (north Congo) and German East Africa, the total of 

 African records having now reached twenty-four. The 

 most southerly is a new one from the Victoria East district 

 of Cape Province (32"^ 46' S. lat.). One previous case of a
