The Endurance of Birds.

out of doors any ordinary winter, Init I do not consider it should 
l)e so kept during" a severe one, nevertheless it is not at all 
fragile, and the protection of four walls is all they require — it 
does not need artificial heat. 
TALrACoi'i Dovio (C. talf^acoti). 1 have found this quietly 
disposed species quite hardy and I have had quite a few of them 
at one time and an.other, but have only had young" fidly reared 
in my a\ iary on two occasions. It is not imported in large num- 
bers, and though one could not call it a free breeder, yet 
individual pairs occasionally have been quite prolific. Miss 
Baker had quite a number of them reared in her aviary, during 
two, or more, successive seasons. 
Picui DovF, (Colui)ibula picui ) : Another species of 
which one may write much that has been said concerning the 
preceding" species — it is a desirable aviary species, rather quarrel- 
some with its own tribe, and fairly ready to nest and rear young. 
I have only had tw"o pairs however, one of wdiich nested and fully 
reared two young birds. Both the pairs fnot in aviary at same 
period) wintered successfully out of doors, but the aviary, 
though the shelter was an open-fronted one, was a very shelt- 
ered one, and from the midland counties northward T consider 
it would be better wintered indoors, but heat would not be 
needed. 
All the foregoing are of small size and very desirable as 
aviary birds, but unless the aviary is a very large one not more 
than two or three species should be kept together, or they are 
apt to interfere materially with each others' nesting arrange- 
ments. The following are all larger species — typical dove-size 
or larger. 
Green-wixged Dove (Chalcophaps indica). I have had 
a long acquaintance with this species, but have been without a 
breeding pair for some years. Quite twelve years ago two 
young birds were fully reared in a very rough aviary, and were 
duly parted with as part of an exchange transaction ; then, the 
following" winter the cock died, btit the hen lived on for twelve 
years, out of doors the whole period, and I will say at once that 
with me they have proved absolutely hardy. Miss R. Alderson 
has not found them so, but it must be remembered that
