The Auk. 
[The Auk : A Quarterly Journal of Ornithology. Vol. xxxviii. for 
1920.] 
The volume of the f Auk 5 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. H. Beck writes on the occult senses in birds, 
one instance of which is the “homing” sense which exists 
to a remarkable 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 ( Cathart'es ), although there 
were known to be none of these birds 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 33 Mr. J. 
Grinnell develops a thesis that among certain non-flocking 
foraging birds, such as lluby-crowned Kinglets ( Regulus ) 
and Audubon Warblers ( Dendroica ), 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. These he groups in three genera, Megaceryle , 
Ceryle , and Chloroceryle. Mr. Loomis identifies Frocellaria 
alba of Ganelin, founded on a bird obtained during Cook’s
