Miss Knobel suggests a most interesting metliofl o£ 

 sexiug Parrots, as a rule a most difficult task. She finds 

 that in the case of males the pelvic bones taper to a point 

 and lie so close to one another that they are touching, 

 whereas in the hen the pelvic bones are wide enough apart 

 to allow an e^^ to pass. This difference can be easily made 

 out in the living bird by carefully feeling it with the fingers 

 in the neighbourhood of the pelvis. A good account of the 

 habits of the Mallee Fowl, one of the mound-building 

 Brush Turkeys of Australia (Le'ipoa ocellata), comes from 

 the pen of Mr. T. P. Bellchambers, and the September 

 number has a fine coloured plate of the Long-tailed lioller 

 {Coracias caiidatus), reproduced by arrangement with the 

 Societe d'Acclimatation de France through the help of 

 Mons. J. Delacour.

 Society for the Protection of Birds has not been able to 

 attempt something of the kind. It is certainly the most 

 attractive of all the j)opular magazines dealing with birds. 

 The six numbers composing the volume for 1921 have each a 

 coloured plate by Bruce Horsfall, Fuertes, or Major Allen 

 Brooks, all consummate bird artists, and there are also 

 numbers of very beautifully reproduced photographs. The 

 January number is chiefly occupied with the annual 

 Christmas census. There are 134 lists of birds noted by 

 various contributors on or about Christmas day from all 

 over the United States and Canada, while one observer 

 sends in a list of 18 species and 313 individuals met with 

 by him at Cambridge, England. As would naturally be
