thousands during autumn on the dead limbs of trees, which were often quite black with them. It was 
evidently their annual meeting preparatory to their migration by taking flight to warmer parts in North 
Australia and elsewhere. Next morning they would be all gone, having departed during the night 
unnoticed, save a few stragglers who had rallied up too late to join the others. At Mullion Creek, 
near Orange, N.S.W., some few years ago, a very large hollow tree had been felled during the winter, 
and strange to say was found to be full of Swallows 
in a torpid state. It was not far from the Mullion 
Creek railway station, and in fairly rough country. 
An egg of the clutch measures in inches = 0°72 
x 0°50. 
EASTERN SWALLOW, 
Flivundo javanica, Sparrman. 
Set of 3 eggs, taken at Thursday Island, Torres 
Straits, North Queensland, on the 3oth of Sep- 
tember, 1895, by W. Black. They are very heavily 
blotched all over, and are a little different to those 
of the previous species. An egg of the clutch 
measures = 0°73 x 0°48. 
WHITE-THROATED FLY BATER OR 
NATIVE CANARY, 
Gerygone albigularis, Gould. 
Set of 3 eggs, taken at South Grafton, Clarence 
River, N.S.W., by Sid. W. Jackson, on the 31st of 
July, 1892. The nest, which is shown in the 
accompanying photograph, was placed in a Spotted 
Eucalypt sapling (Eucalyptus maculata), on Blanch's 
Ridge. The beautiful dome-shaped nests of this 
bird are often placed in saplings which are covered 
with ants, and it would be interesting to know why 
such trees are chosen. In the Clarence River 
district we have sometimes found these pensile 
nests placed in trees at an altitude of 50 feet, and 
in such cases they are well hidden from the eye of 
the collector. The nests are constructed of bark, 
and are sometimes over a foot in length, the tails 
being very long. This sweet singing Fly Eater, 
which is better known as the Native or Bush 
Canary, was very plentiful everywhere last season 
(1906), and I found it very common about Sydney. 
In some nests, which contained an egg of the 
Bronze Cuckoo, I found that there was an opening

Taken by T. Williams, near Rockhampton, Queensland, on the 3rd of December, rgor. An egg 
of the Little Bronze Cuckoo was found with this set of 3 eggs. Specimen A. measures = 0°71 x 0°46.

Chalcococcya malayanus, Rafiles. 
One egg, taken with latter set of eggs. It measures in inches = 0°74 x o'50.
