[L’Oiseau. Revue (THistoire naturelle appliquee. Vol. i. for 1920. 
12 nos.] 
This is a new journal which has recently reached us. 
It is published by the Societe nationale d’Acclimation 
of France, and consists of two parts, the first dealing 
with Mammalogy, Pisciculture, Entomology, Botany, and 
Colonization ; the second with Ornithology. The President 
of the Ornithological Committee is M. Jean Delacour, 
well known to English aviculturists as a most successful 
breeder of wild birds in captivity. The new journal is run 
very much on the same lines as our British c Avicultural 
Magazine/ and many of the contributors to the first volume 
now under review hail from this side of the Channel. 
After an introduction on the beauty and usefulness of 
birds and the delight which we find in studying their ways 
and habits, by Mr. Edmond Perrier, who is the President of 
the Society and the Director of the Museum of Natural 
History, Mr. Seth Smith follows with an account of the 
bird-houses in the London Zoological Gardens. There 
are also articles by Mr. H. D. Astley and Wesley T. 
Page. 
The principal French contributors are M. Delacour, who 
has an interesting notice on his experiences with living 
Humming-birds, and M. A. Decoux, who describes some 
remarkable Weaver-bird hybrids, one of which (Zonogastris 
melba x Estrilda phoenicotis) is figured in colour. There 
are two other coloured plates of the Gang-gang Cockatoo, 
Callocephalon galeatum, by M. A. Millot. M. Delacour is 
hoping to be able to breed this rare species in captivity. 
He has a fine male which he hopes to mate with a hen 
belonging to the Marquis of Tavistock. 
There are many other illustrations, reproduced from 
photographs and drawings, to accompany articles by other 
aviculturists. We wish every success to the new venture 
of our brave allies.
