THE JACKSONIAN OOLOGICAL COLLECTION. 
in a tall Blue Eucalypt (Eucalyptus saligna), which was nine feet through. Both these nests were place 
at an altitude of over ninety feet, and within half a mile of one another, and in 1895 my brother climbed 
up to them, and although they appeared quite clean and new, they contained no eggs; it was very 
disappointing after such tedious and difficult climbing. Our first set of these eggs was taken from a 
tall Blackbutt Eucalypt (Eucalyptus pilularis) near the sea shore, south of the Clarence River Heads, 
during September of 1896. The eggs vary both in size and shape, and I have seen some specimens 
very round, though as a matter of fact they are in most cases pointed ovals, such as the set now under 
notice. I engaged two aborigines at Grafton during season 1895, to go hunting for the eggs of this 
eagle, and equipped them with the necessary rations, etc., and after a month’s absence they returned, 
their spoil consisting of a few Soldier Birds’ and Magpies’ eggs; I was disgusted, and never sent them 
on such a mission again. I found that these darkies will not hunt or climb unless they are directly 
under your personal supervision. Of set No. 257 Specimen A. measures = 2°88 x 2°09, and 
has many marks or nest stains on it, and no doubt when first laid both eggs were quite white. Speci- 
men B. measures = 3.07 X 2°09. 
WHITE-HEADED OSPREY, 
Pandion leucocephalus, Gould. 
This very handsome clutch of two eggs was taken at North-west Cape, Western Australia, by a 
collector engaged by G. A. Keartland, on the 29th of July, 1897. The nest was constructed of sticks 
and lined with sea weed, and placed on a low rock on the sea coast. We have seen this fine bird on the 
coast of Queensland and New South Wales, but were never fortunate enough to find any of its nests. 
Specimen A., which is beautifully blotched, measures = 2°57 x 1°90. Specimen B. measures =

WHITE-HEADED SEA EAGLE, 
Hfaliastur girrenera, Vieillot. 
This pair of rareeggs was taken by C. Woodlands from a very tall tree on the banks of the 
Nicholson River, North-west Queensland, on the 16th of January, 1897. The eggs of this bird are 
represented in very few collections. Specimen A. is much larger and less marked than specimen B., 
and measures = 2°23 x 1°68. Specimen B. is a smaller egg, and is very finely marked all over, and 
no person would ever think it came from the same nest : it measures = 2°05 X 1°57. 
WHISTLING EAGLE, 
FTaliastuy sphenurus, Vieillot. 
This handsome clutch of 3 eggs was taken on the 21st of August, 1898, by L. Vesper, W. Crawford, 
Frank and Sid. W. Jackson, from a nest found in a large Spotted Eucalypt (Eucalyptus maculata), at 
Gerrymberrym, Upper Clarence River district, New South Wales. See accompanying photograph. 
From this the birds commanded a splendid view, and could survey the whole of the surrounding 
country, as the tree which contained the nest stood in such an elevated position on the ridge. This 
set varies greatly in the markings, and Specimen A. is the best marked egg of this Eagle that I have 
ever seen, and as we have from time to time handled nearly 70 of these eggs, my choice therefore, in 
claiming this specimen as an exception to the rule, has been made from the total result of many years 
of arduous collecting and practical experience. It measures = 2:25 x 1°67. Specimen B. is a much 
rounder egg, and the markings are not so large, it measures = 2:28 x 1°75. Specimen C. is the 
smallest egg of the three, and the markings are of a dull purple, the majority of which appear as if 
beneath the surface of the shell, a peculiarity which is noticeable in the eggs of many birds ; it measures 
= 2°23 x 1'64. ‘These birds seldom lay three eggs for a sitting, two usually being the full complement. 
During our residence in the Clarence River district we climbed to 73 nests of this Eagle, and the full 
history of which would alone fill a book, and from which we procured eggs from nearly half; some- 
times they built near the edge of the swamps and creeks, in Swamp Oak trees (Casuarina glauca), ata 
height of only 45 feet, but they generally confined themselves to the very large trees on high ridges, or 
hills, and any eggs we got were always well earned. I noticed that these Eagles usually sallied forth in
