My Breeding Results, Etc. 
other birds. Another small aviary (i6ft. x T6ft. ) I am thinking 
of letting a pair of Ked-rumped Parrakeets {Pscphotiis 
iLicmatoiiotus) have the sole occupancy. 
In my aviary this season I have only bred the following 
so far : — 
5 Peach-faced Lovebirds (Agapurnls roscicoUis). 
I Cockateel (Calopsitiacus iwz'ac-lioll(i)nliac). 
3 Green Budgerigars {M clopsittacus iiudulatiis). 
3 Yellow Budgerigars (M. nndulatus var. lutcus). 
I have two pairs of Cockateels. but I have had bad luck 
with them. The first clutch of eggs was broken, owing to an 
insecurely fixed barrel falling down, and the other nest w'as 
nullified by the interference of lovebirds. i neir next clutch 
was laid in a box with a flat bottom; the eggs rolled about, got 
chilled, and did not hatch out. '1 ne other pair reared one 
young bird, which is now qriite independent of its parents. 
After this I was afraid they would not nest again this season 
but about the middle of August both pairs went to nest again, 
this time in boxes with a long entrance run ( I find these boxes 
are nuich liked by all parrakeets). On examining these nests 
to-day (.September 30th'), I find four young birds in one, and 
three in the other, so, I think, the cockateels will have done 
fairly well, if nil these young are reared. 
Budgerigars, of which I have five unrelated pairs, have 
been a failure, as only six young birds have been reared, all the 
other nests having infertile eggs. The six young birds reared 
were one brood, and were the offspring of a Yellow cock, and 
Cvreen hen. The same pair are now nesting again. 
Red-headed Finches (Amadina erythroccphala) were also 
a failure. They laid several clutches, but did not hatch out a 
single chick; one nest had chicks dead in shell. 
Blue-winged {l''sitianila passcriua) and Madagascar 
(Agaponiis inadagascaricnsis) Lovebirds made no attempt to 
nest whatever. 
The cock Canary-winged Parrakeet was very anxious to 
kill the hen budgerigar who had young; he gradually enlarged 
the entrance to the nest, and would very soon have worked his 
malice upon her, had I not caught him up and clipped a few of
