pairs before a storm, circling high overhead, and frequently uttering their peculiar loud whistling cry. 
They have a decided liking for fish, and these they pick up on the banks of rivers and creeks, and 
chiefly comprise those of the common fresh water Cat Fish (Copidoglanis fandanus) and Eels (Angnilla 
veinhardtii), which the fisherman cast aside. During their piscatorial feasts these Eagles leave quantities 
of fish, etc., in the nests, which soon decay and gives them a filthy and repulsive appearance. 
The nests measured from two to three feet across. During 
season 1897 I found a nest of the Black-shouldered Kite (Elanus 
axillaris) being built ina tall Eucalypt in Walker’s paddock, at 
Dallinga, South Grafton, and when the Kites had quite finished 
building it, the Whistling Eagles took possession and hunted the 
Kites away. Later on, however, I took a beautiful clutch of 
Eagles’ eggs from this very nest (see data No. 262), and as the 
bird sat thereon a great portion of her was plainly visible from the 
ground, and her tail projected far over the edge of the Kite’s 
small nest. We have taken the eggs of this Eagle during every 
month of the year, as the following dates will show :—

Taken on roth July, 1898, in Spotted Eucalypt (Eucalyptus 
maculata) in Parkinson's paddock at Caramana, near Grafton, 
Clarence River, N.S.W., by Frank and Sid. W. Jackson. The 
nest was placed at an altitude of go feet, and the eggs were 
obtained by my brother, Frank T. A. Jackson, who chopped steps 
into the tree and used a strong green vine to hold on by. oo Prask "Tt A. Tabkeon up onreltapenete

markings. Specimen A. is beautifully blotched and marked with (See data No, 260.) 
reddish-brown, and particularly at the larger end, and measures 
= 2°25 x 1°65. Specimen B. is a very strange looking egg, and no person would ever think it came 
from the same nest. It is absolutely devoid of all natural markings of the reddish-brown form, and is a 
dirty white, covered all over with smudges or nest stains of a light yellowish-brown. It measures =

This is a very fine set of 2 eggs, the ground color ot which is nice and clean, and they are well 
spotted with rich reddish-brown markings. Specimen B. has the zone of markings at the pointed end, 
while Specimen A. has it at the thick apex. We collected this set just as a severe hail storm was 
coming on, and before my brother took the eggs from the nest one of them got slightly fractured by a 
hailstone striking it after the Eagle flew off. ‘The nest was built in an upright limb of a Red Eucalypt 
(Eucalyptus vostrata), growing in Walker’s paddock on the edge of Duck Swamp at Dallinga, South 
Grafton, N.S.W., and was robbed on the 15th of August, 1897. Taken by Frank and Sid. W. Jackson. 
The nest in which this set of eggs was deposited was built by a pair of Black-shouldered Kites. The 
Eagles, however, hunted the Kites away, and took possession of it, and the latter then resorted to and 
laid in the Eagles’ old nest close by. Specimen A. measures in inches = 2°27 xX 1°73. Specimen 
B. measures = 2°27 X 1°70.
