of the country, the nests are difficult of access. One sea eagle’s 
nest (Plate xiv., figs, i and 2) found on the east coast contained two 
eggs. It was a very bulky structure, the diameter on the top being 
183 c.m., at base 240, height 52 ; the mould was only 65 wide by 12 
deep. To reach the nest it was necessary to make a detour of at 
least a quarter of a mile to find a spot where one could climb down 
to the shore, about 40 feet below. Both eggs were slightly incu- 
bated. Two other nests of this eagle which I found on August 
27th, contained young birds at least a fortnight old. On August 
20th, during an excursion southwards, I found eight nests of the 
Osprey, of which several were old and deserted. It is more plenti- 
ful than the Sea-eagle, for five of these fine birds were in sight at 
once. A nest visited on August 7th was on a projecting cliff, and 
contained three young, two about a fortnight old, and the other 
about a week. It measured across the top 141cm., base 160cm., 
mould 59cm., depth of same 6cm., height of nest 88cm. Both 
parent birds and their young were secured (Plate xv.) 
A remarkable find on this island was the nest with two young 
of Uroaetus audax (Plate xvi.), for owing to the total absence of trees, 
it was built on the side of a hill to secure a good outlook. It was 
situated about 15 yards from the top of the hill, and 35 from the 
foot. Across the top the nest measured 196 cm., at bottom 244 cm. 
The height on the upper side, top, was 53cm., and on the lower, 
260cm. 
Besides eagles, there were large colonies of Cormorants, Sea- 
gulls and Terns ; these had quite finished their nesting. 
The breeding season of the smaller birds, Maluvus, Sericovnis, 
Megalurus, etc., had finished about the end of May. They were 
always to be found in family groups of two old and three or four 
young birds. These were not common, for one often tramped mile 
after mile without seeing a single bird. 
Bernier Island has the same desolate appearance as Dorre, 
perhaps even worse, as there are no flowers and the scrub is thicker. 
To travel a mile and a half per hour may be considered good work, 
and even that is very tiring. 
The animal life is nearly the same as on Dorre Island, with the 
exception of Megalurus, which is not to be found here, and the 
Eagles and Ospreys are not so numerous as on Dorre Island. I
