The Endurance of Birds. 
ile, and the marvel is tliat it lasts out the short period it is occii- 
l^ied — in my aviary the same nest was never used twice. 
'Sc.\]A- T^oxK (Scardafclla squojuata) : I have not bred 
tliis species; moreover, the one pair I have possessed onlv 
remained in my aviary fifteen months, l:)eing" then passed on 
owing- to my dove acconmiodation being much overstocked. 
They passed through one severe winter with me and they cer- 
tainly did not show any discomfort, being quite fit and vigorous 
when it had passed. It has been bred at the London Zoo, and by 
one. if not more, ])rivate aviculturist. Tt is rather a prettv little 
soecies, and nnich more alert in its demeanour than are Coliiin- 
hi lac generally. It is not a conmion species in the bird market. 
C.WK Dove (Ocna cafcnsis): This is a very pretty 
species indeed, but is only half-hardy — there are however, excep- 
tions to this rule, for instance an odd hen in my largest aviary 
has been left out this winter, and so far is in really exquisite form 
but she always sleeps in the shelter and does not need driving in. 
However, the general experience is that it is best brought 
indoors at the end of October and kept there till the followins^ 
May. It is not a prolific breeder in captivity, and, although it 
has nested, no young have been reared in my aviary, but others 
have been more fortunate in this respect. 
Dw.ARF Ground Dove (Chainac pclia griscola) : A min- 
ute and interesting species, first bred in captivity by Mr. W. E. 
Teschemaker; it has also reared young in my aviaries, but, as 
it is rather imcommon on the market only a comparatively few 
aviculturists have had the opportunity of testing it in this 
respect. My experience is that while it can successfully pass any 
ordinary winter out of doors, a really severe one would cause 
real discomfort, even if the bird managed to survive it. In the 
southern counties it could perhaps be treated as hardy, but it is 
not so in the north — my personal experience only covers the 
London district with this species. 
Passkkixe Dove fCIianiacpclia /^asscriiia) : An interest- 
ing; but shy species, spending" most of its time in cover, but 
nevertheless fairly ready to reproduce its kind in captivity. Ore 
young bird only has been reared in my aviary. Mr. H. Willford 
was the first to rear young in this country. This is also safe
