The Auk. 



[Tlie Auk : A Quarterly Journal of Ornithology. Vol. xxxviii. for 

 1920.] 



The volume of the ' Auk' for last year contains a good 

 many articles of general interest as well as many faunal 

 papers which are more attractive to those living on the 

 other side of the Atlantic. 



Mr. H. n. Beck writes on the occult senses in birds, 

 one instance of which is the "homing" sense which exists 

 to a remarkal)le degree not only in the homing pigeon but 

 also in certain sea-birds. The experiment undertaken at 

 the marine laboratory of the Tortugas in releasing Sooty 

 Terns many hundreds of miles away from those islands and 

 the return of these marked birds, has proved the existence of 

 one of these. An instance of another mysterious sense is the 

 food-finding instinct. A carcass of a dog hidden in a hole 

 and quite invisible from above was discovered within three 

 hours by a pair of Buzzards (Cathartes), although there 

 were known to be none of these 1)irds within many miles, 

 and Mr. Beck believes that it would have been impossible 

 to detect the carcass either by sight or smell. 



In an article entitled " sequestration notes " Mr. J. 

 Grinnell develops a thesis that among certain non-Hocking 

 foraging birds, such as Ruby- crowned Kinglets [Regulus) 

 and Audubon Warblers (Deiidroica), a special note exists to 

 warn other birds to keep out of territory already occupied; 

 while Mr. J.T. Nichols writes at length on the voices of the 

 Wadeis or Shore-birds, of which he has made a life-long 

 study, especially on Long Island. 



A valuable paper on the generic and specific characters of 

 the Ceryline group of Kingfishers is contributed by Mr. W. 

 de W. Miller. Tiiesc he groups in three genera, Megaceryle, 

 Ceryle, and Chloroceryle. Mr. Loomis identifies Procellaria 

 alba of (xmelin, fouiulcd on a bird obtained during; Cook's
