surprised, seeing they had only been in the aviary eight days. 
The nest was completed and the first egg laid on July 
17th; incubation commenced July i8th; the first egg hatched 
July 30th, making incubation perod twelve days. 
The first youngster left the nest on August 13th. The 
clutch consisted of three pale bluish-white unspotted eggs. 
All three hatched out, but none of them were fully reared. 
The weather was very wet and cold during the time they 
were nesting, which shows how some individuals will readily 
nest while others under favourable conditions refuse to do so. 
I received twenty-five Indigos from Mexico on August 
28th, 1910, and fifteen more on June ist, 1911; I kept several 
pairs but none of them attempted to nest. 
Nonpareil Buxtixg ( Cyaitaspica ciris). 1 i)urcluised my 
first Nonpareil in 1903. He moulted alright in the Autumn, 
but his Vermillion brea.st faded to orange-yellow. He 
W'intered in the outdoor aviary 1903-4, but, as he probably did 
not get sufficient insect food, failed in health and was eventually 
killed by a Red-billed Weaver. 
Received another June 1904. He wintered out of doors, but 
again, like the first one, lost his red breast ai'er the moult. The 
following summer, he paired with a hen canary, and afterwards 
with a hen greenfinch, but all the eggs were infertile. He 
paired with a hen canary in 1906 and 1907 but again the eggs 
were clear. I caged him during the winter of 1908, givmg him 
two or three mealworms daily. His breast was now deeper in 
colour. 
The Nonpareil is not one of the easiest birds to keep in 
health and condition. It requires some kind of insect food 
daily in addition to its ordinary diet of canary and millet seeds. 
Then in the outdoor aviary in the summer it, of course, gets 
a lot of flies and other insects, but as there are few insects 
during the winter it is advisable to cage "t and give a few 
mealworms and as many spiders as possible,
