of the holes in tree-trunks. All these have had a bad effect 
on some of those species formerly abundant. An inter¬ 
esting chapter deals with this subject, and another discusses 
the number of individual birds in certain limited areas— 
bird censuses, in fact—-but the bulk of the volume is 
devoted to an annotated list of species with supplementary

Bird Notes. 
[Bird Notes: The Journal of the Foreign Bird Club. Edited by 
Wesley T. Page. Ser. 3. Yols. ii. & iii. for 1919 & 1920.] 
It is, we regret to say, some time since we noticed 
‘ Bird Notes,’ and we have two volumes for 1919 and 1920 
now lying before us. Among principal contributors are 
Mr. Baily W. Shore, Dr. E. Hopkinson, Mr. Amsler, the 
Marquis of Tavistock, and the editor himself, who appears 
to be responsible for the last half of the matter contained in 
the two volumes. We much regret to see that Dr. Lovell 
Keays, another enthusiastic aviculturist who formerly sent 
many good articles to this magazine, died in May last year 
from the effects of mental and physical strain during the 
three years of the war. 
Among the longer and more important contributions to 
these two volumes must be mentioned the carefully com¬ 
piled list of all species of birds which have bred in captivity, 
by Dr. Hopkinson, and the very practical articles by the 
Marquis of Tavistock on Parrots and the best methods of 
keeping them either in aviaries or in the open. There are 
also several contributions from the United States. Australia, 
and France where M. Delacour has re-established his aviaries 
destroyed during the war. He sends a detailed account 
of the successful breeding of the West African Touraco 
[Turacuspersa). Only one species of this family had been 
previously successfully bred in captivity. 
We regret to see that there appears to be a strong feeling 
among the members of the Foreign Bird Club against
