which is very Owl -like— shooting up on to a hranr-h and 
instantly closing its wings without the preliminary fiutter 
characteristic of most large bii'ds. Unlike Roseates and Bank- 
sians {Cal>/ptorhi/?}chus hanlxsii), Gang- gangs seldom take a 
sustained flight of a Inile or more at a Itime, neither do they 
ever rise high in the air, and after circling I'ound several 
times return to their original perch. 
When spring- came round the pair began to find their 
voices again and in the early mornings would indulge in the 
most inharmonious duets which sometimes lasted for more 
than half an hour without a pause. They also tegan to 
look about for a nesting-site, and finally selected the hollow 
branch of an oak tree about fifty feet from the irround. 
Both sexes took part in the incubation of the eggs, and the 
cock sat quite as much as the hen, whom, however, he never 
attempted to feed. For a long time we were uncertain 
whether young had been hatched or not, but after about eight 
weeks the old birds' visits to the nest became infrequent, and 
finally ceased, and examination revealed nothing Iiut three 
infertile eggs — a disappointing result, but, considering the 
crippled condition of the cock, a very natural one. The eggs 
were rather large, round in shane, and of a dirty whi^e coloui'. 
The following autumn I bought two pairs of young 
Gang-gangs, which the dealer, undeterred by the fact that 
one of the cocks was still in down and quite destitute of quill 
feathers, informed me had been flying for some time in a 
gentleman's outdoor aviary. I put them into a cool indoor 
flight but, on the temperature falling below 50 degrees, two 
of them became so ill that they nearly died and I hastily 
caged the lot and brought them into a warm room. For a 
time they did very well, displaying for some weeks a curious 
habit of roosting, clinging head downwards from the tops of 
their cages— more like Hanging Pavrakeets than anythinq- 
else. Although so young and in very rough plumage both 
cocks showed much aflfection for their mates, and, an intense 
dislike for one another. About the middle of December one 
of th(^ hens died suddenly and the post morfrm revealed 
fatty degeneration of the liver— the result of a too liiveral 
indulgence in hemp and sunflower. T!oth these seeds are bad 
for caged Gang-gangs, and are best omitted altogether from 
their dietary. ' ^ ' ! '
