fi'om the north and oast, and catehes the sun somewhere during 
all hours of the day. 
The above description and the i)lans should make 
all the arrangements clear. There is nothing to record re- 
garding the birds in this, as the birds have but recently 
been transferred thereto. 
1913 In The Old Aviary: The season was a very 
mixed one and brought many disappointments. 
Cockateels. — For the second year in succession these 
failed to hatch out; the eggs, three in number, apparently 
infertile, on being opened, were found to be dried up. 
White Java Sparrows. — These built a large nest in 
a covered box, depositing three eggs therein, but the hen, 
after incubating for some time, was found dead in the nest. 
Senegal Doves. — These ne.-;ted thre'^ times -the nestlings 
did well until they left the nest, whereupon they all went 
"wrong" in the legs and eventually died. The nest — of the 
flim.siest construction — was built in the remains of an, old 
Xmas tree in the shelter, which is quite a dry place, so that 
the trouble cannot, I .should think, have been damp and crimp. 
I fancy the old birds were too anxious to go to nest again 
;ind neglected their progeny, which then developed rickets 
nr something similar. 
Chaffinches. — Built a perfect nest in a box bush, and 
out of a clutch of three eggs hatched out one chick, which 
died almost at once. 
Hybrids. — My fine cock Bullfinch, after flirting with 
a hen f'haflinch, eventually settled down with a hen Linnet as 
partner. She built a nest in some ivy and laid three eggs, 
but the nest was pulled about by some other bird. However, 
she built again in a box bush, sat patiently for a month 
and then gave up— the eggs being infertile. 
A cock Black -headed Nun mated with an odd hen 
Zebra : Finch, built a nest in a covered box, and laid three 
eggs; of these two hatched and did well until nearly fledged, 
when for some reason they died. In the nestling plumage 
they resembled their mother and did not appear to show any 
trace of their male parent. 
Zebra Finches. — These did fairly well as usual, and 
would have done even better, but for their habit of laying 
in the nest again before the previous brood had flown.
