THE BIRDS OF AUSTRALIA. 
All these flights of Wood-Swallows were accompanied by flocks of Ephthianura 
tricolor, and by small numbers of the Pied Honey-Eater ( Entomophila 
leucomelas). A number of the present species remained to breed in the 
scrub just on the edge of the spinifex plain. I examined a dozen or two 
of their fragile, ill-constructed nests. None contained more than two 
eggs. The nests were placed in a variety of situations. W T hen I passed 
through the spinifex on my return in November not a Wood-Swallow 
was to be seen.” 
Captain S. A. White has written about his trip to the Gawler Ranges : 
“ On one occasion only did we meet with these birds ; that was in the centre 
of the ranges on 15th September, 1912, a day to be remembered, for the wind 
had been blowing with great force for many days, but on that day it seemed 
to excel in energy. Although we were camped under the lee of a steep spin 
in thick mulga scrub, it was almost impossible to light a fire or keep a duck 
tent from blowing to pieces. In a gully close to our camp we came upon 
a vast host of these birds, sitting on the ground, or holding tightly to the 
lower branches of the mulga to try and escape the terrific wind as much as 
possible. No doubt they were migrating prior to nesting, and had been 
forced to take shelter from the elements.” 
Macgillivray has written : “ First noted in the Gulf (Queensland) on 
8th June, when on the Leichhardt road. On the 12th June, a large flock 
passed the camp at sundown, flying north. Again seen on the Gregory 
River on 22nd July, 1910. Great numbers of this migratory species 
appeared in Western New South Wales early in August, 1910, and continued 
to arrive until well on into September. Very few, however, remained to 
nest.” 
Under the name Artamus super ciliosus, Cleland has written the following 
in his Birds of the Pilliga Scrub , N.S. W. : “Wliite-browed Wood-Swallow. 
A few birds of this species and of the following were seen throughout the 
journey at odd places, but in the neighbourhood of Merebene and Wangan 
they were found in large numbers, resting in white cypress-pines ( Gellitris 
robusta), eucalypts, and dead ring-barked trees on the edges of cleared 
land. Early one morning, every half-hour or so, they rose in a cloud into 
the air, probably 200 or more being seen at one time. The cloud of birds 
gradually circled higher and higher, making a great noise, and separating 
as they rose. Finally they made their descent and returned to the trees. 
The two species were intermixed, though probably A. personatus pre- 
dominated. Noticing that the birds were congregating on the upper branches 
of some of the white cypress-pines, I approached close to them, and was 
surprised and interested to notice that they were apparently feeding on
