Fauna och Flora. 



[Fauna och Flora. Popular Tidskrift for Biologi. Utgifveu af 

 Einar Lonuberg. Vol. for 1921 ; 6 parts.] 



Dr. Lonnberg^s magazine of natural history for last year 

 contains a good nutnber of articles on ornithology, from 

 which we select the following titles. Mr. S. G, Blomqvist 

 and E. Rosenberg have a long paper on the birds of the 

 Nerike district of central Sweden, a region abounding in 

 swamps and lakes. The birds are arranged ecologically 

 according to the kind of vegetation which they most affect : 

 for instance, Acrocephalus streperus, Circus eeruginosus, 

 Fulica atra and others are associated with the reed-beds 

 {Arundo phragmitis), Circus cyaneus with the patches of 

 willow along the shores of the lakes and seas. Dr. Lonnberg 

 himself contributes several notes on birds ; he records the 

 occurrence of the Surf Scoter, Oidemia perspicillata, in the 

 Baltic, and Larus argentutus cachinnans the Mediterranean 

 Herring-Gull — a new record for Sw^eden, also taken on the 

 Baltic coast. He also describes a curious albino Gull, 

 which he identifies as Larus mariuus, and has an interesting 

 article on the biology of the Woodcock. From Mr. H. 

 Zetterberg there is a list of the dates of the arrival in 

 spring of various birds in southern Lapland, and as the 

 records have been kept from 1906 to 1919 a good average 

 date can be struck. Mr. I. Hilden has an article on the 

 birds of Runo, a little island in the middle of the Gulf of 

 Riga, and Mr. K. Kolthoff on the history of our know- 

 ledge of the birds of the island of Oland, whence Linnseus 

 described a good many species. Mr. R. Palmgren records 

 for the first time Gyps fulvus from Finland, and Graf Zedlitz 

 discusses the races of the Jackdaw, Coloeus monedula.
