the Chillan Sea 
Hagle (Gerano- 
aétus melano- 
leucus)—1s a native 
of South America, 
and is a very 
beautiful example 
of the “king of 
birds.” The sea 
eagles include the 
largest members 
of the whole 
family; they build 
enormous nests, 
sometimes six Or 
eight feet in 
diameter, and in- 
stances have been 
known of birds 
returning to the 
same “horst”’ for 
twenty years in 
succession. Hvery 
year some addition 
is made to the nest 
until it becomes 
five or six feet 
high. Two eggs 
are generally laid, 
and the male and 
female sit alter- 
nately. 
The other bird— 
the Hmu—is every 
day becoming 
more scarce. The 
peculiar booming 
note uttered by 
the female emu 
must have been 
remarked by any- 
one observing 
these birds at the 
Zoo. The sound

a singular orifice 
in front of the 
wind-pipe, com- 
municating with 
a tracheal pouch, 
this peculiarity 
being confined to 
the hen, which 
on account of its 
large size may be 
readily mistaken 
for the cock bird. 
During the breed- 
ing season the 
hen bird utters 
this remarkable 
percussive boom- 
ing note, no doubt 
to attract the male 
bird. The emu is 
the second largest 
existing bird, being 
only slightly 
smaller than the 
ostrich; it is equally 
swift of foot, rival- 
ling the kangaroo 
in speed, and 
affording good 
sport when chased 
by dogs; but when 
if is within close 
range, great care 
has to be exercised 
that one does not 
get within reach 
of the outward 
and backward kick 
of these birds, 
which would bring 
aman down easily, 
and often with 
severe wounds, 
their legs being 
exceedingly 
powerful.
