tion as the aviary permitted. It is a hardy species, but in conse- 
quence of its spending" most of its time upon the ground, it 
usually loses several toes during' a severe winter from frost-bite, 
but this does not, according to my experience, interfere at all 
with its l)ro(iucti^•eness. Two young were reared in my aviary 
last season and young have been reared several times in previous 
years. Full details have been given in Bird Notes by Mr. R. 
Suggitt and others, so that I need not recapitulate them here. 
They are quite inoffensive in a mixed aviary. 
NivCKLACK DovK (T . tigriniis). This species is found in 
Burma, Malay I'eninsula and adjacent islands and the Moluccas. 
I have not succeeded in breeding this species, and my 
experience has been confined to a single pair and a single season. 
Dr. A. G. Butler has bred this species, and a pair in Miss 
1\. Alderson's aviary were very prolific. Both Miss Alderson 
and Mr. W. Shore Baily have reared very beautiful hybrids 
between this species and the Senegal (T . sciicgalcusis). 
It is quite hardy, but must not be allowed to nest during 
the winter months, or eg"g-binding usually results. 
Jam Arr.w Pea Dove ( Zcnaida amahilis ). Almost a replica 
of Z. aiiiita, an.d an eciually pleasing species, is very ready to 
nest, and a good portion of the squabs hatched out are usually 
reared without trouble. With me it proved quite hardy and 
inoffensive. ( )ur member Dr. Thwaites imported a few some 
years ago and kindly presented me with a pair. He succeeded 
in lireeding several broods, an accoimt of which was published 
in this Journal. My pair also bred, as indicated above. I have 
only possessed the one pair; an accident accounted for the hen, 
and as I had no Aurita hen at the time and another Pea hen being 
improciu^able, I parted with the odd male — they are very seldom 
imjTorted.

have had several pairs but they never got as far as eggs with me. 
Lord Poltimore and, I think, Mr. H. E. Bright have successfully 
bred them, but success with this species is not common. I found
