" Egg-Carrying by Birds," by T. Steel. Australian Naturalist, 

 vol. iv., p. 52. 



The author observed that a domestic hen, whose eggs had been 

 removed from the nest, carried them back over an obstacle by 

 pressing them against her breast with her beak, and suggests that 

 perhaps Cuckoos convey their eggs in the same manner, and not 

 actually in the beak, as is commonly supposed. 



" How Birds-of-Paradise are Caught," by An Old Australian 

 Bird-Lover. Aviciiltural Magazine, vol. ix., p. 274. 



An interesting account of the methods employed by a bird 

 dealer in obtaining live specimens of Birds-of-Paradise and other 

 rare species in New Guinea. 



" Colour Change Without a Moult," by Dr. A. G. Butler. Avi- 

 cuUtiral Magazine, vol. ix., pp. 285-303. 



" Evidence that Many Birds Remain Mated for Life," by F. C. 

 Willard. Condor, vol. xx., p. 167. 



"Problem: Do Birds Mate for Life?" J. E. Law. Condor, 

 vol. xxi., p. 26. 



" Evidence that Many Birds Remain Mated for a Number of 

 Years." N. K. Carpenter. Condor, vol. xxi., p. 28. 

 The three articles on this subject mentioned above are very 

 suggestive, and include many interesting observations. It would 

 be interesting to have evidence as to the habits of Australian 

 birds in this respect. 



" Parasitism of Nestling Birds by Fly Larvae." O. E. Plath. 

 Condor, vol. xxi., p. 30. 



The author iinds that in America a considerable proportion of 

 Passerine birds are subject, as nestlings, to the attacks of larvae 

 of a fly, which suck their blood. The fly, in its turn, is kept in 

 check by a parasite, a chalcid wasp {Nasonia brevicornis), the 

 same species which is being artificially reared in Australia to 

 assist in checking the ravages of the sheep blow-fly. The attacks 

 of the fly larvse result in a considerable mortality amongst the 

 nestlings. Do Australian birds suffer in this way ? 



" Birds of the Panama Canal Zone." W. Stone. Proc. Acad. 

 Nat. Sci. Philadelphia, vol. Ixx., p. 239. 



The fact that no less than 432 species are now known from 

 this comparatively small area shows the richness of the bird-life. 

 Reference to this paper may be of interest to Australians who 

 travel to Europe via the Panama Canal, as suggesting what birds 

 they may see, though descriptions of the species are, of course, 

 not included.
