THE JACKSONIAN OOLOGICAL COLLECTION, 
BLACK FALCON, 
Falco subnigey, Gray. 
Set of 2 eggs, taken from the topmost branch of a tall Spotted Eucalypt (Eucalyptus maculata), at 
Lavadia, near Glen Ugie Peak, Clarence River district, N.S.W., by W. and J. McEnerny, Frank and 
Sid. W. Jackson, on the 3rd of November, 1895. See accompanying photograph, showing my brother 
up at the nest. This bird is chiefly confined to the more interior provinces of Australia, and seldom 
comes to the coast to breed, and this is the only time 
we observed it on the Clarence River. The eggs were 
laid in an old nest of the Whistling Eagle, and the 
ground beneath it was covered with quite a collection 
of bones and skulls of various small animals, which 
bore testimony to the many past feasts of these eagles: 
We frequently found their nests, and the ground 
beneath, strewn with bones, etc., and also numerous 
vertebrae of the common fresh water Cat Fish (Cofi- 
doglanis fandanus). Specimen A. is richly marked, 
and measures = 2°17 x 1°66. Specimen B. = 2'17

GREY FALCON, 
Falco hypoleucus, Gould. 
This rare set of 2 eggs was collected at Emerald, 
Mackenzie River, Queensland, by T. Williams, on the 
23rd of September, 1898. The nest was placed in a 
Eucalypt, at an altitude of nearly 7o feet, but was 
comparatively easy to rob. I never remember seeing 
this bird on the coast of New South Wales ; like the 
former, it is more confined to the interior parts. 
Specimen A. measures = 1'99 x 1°55. Specimen 
B. measures = 2°06 xX I'55. 
LITTLE FALCON, 
Falco lunulatus, Latham. 
This splendid set of 3 eggs was taken at Ti Tree Frank T. A. Jackson up at the nest (aboye black 
Creek, near South Grafton, Clarence River, N.S.W., ee ian ay Re eee eee Sigh 
on the 7th of October, 1894. The nest, which was (See data No, 251.) 
constructed of sticks, and lined with Eucalyptus leaves, 
was placed in the topmost branches of a giant Spotted Eucalypt (Eucalyptus maculata), at an altitude of 
go feet, and was a very difficult and dangerous climb. Taken by J. McEnerny, Frank, and Sid. W. 
Jackson. We noticed very few of these Little Falcons in the Clarence River district, and only succeeded 
in finding this one clutch of eggs. It seems very remarkable that all the Accifitres in the latter district 
build so frequently in the Spotted Eucalypti ; many of these trees, which grow to an immense size, and 
are situated in prominent positions on the ridges looking down into the rich Clarence River valley, 
often have large nests, or the remains of them, in their lofty boughs, and are very conspicuous, and 
can be seen a long way off, the majority of them being those of the Whistling Eagle. An average 
specimen of the set under notice measures = 1°62 x 1°31. 
NANKEEN KESTREL, 
Cerchneis cenchroides, V. and H. 
Splendid clutch of 4 eggs, taken from the hollow spout of a dead Eucalypt on the south bank of 
the Orara River, near Ramornie, Clarence River, N.S.W., by W. McEnerny and Sid. W. Jackson, on 
the 26th of October, 1897. I found this bird very common about Toowoomba, Q., and frequently
