half inches in extreme diameter, thickest at the rim and very slightly dished 
in the centre. A few feathers had been worked into the outer part of it, which 
was hardened with glutinous matter produced by the bird. The two birds at 
the first nest made no attempt to fly, and allowed themselves to be drawn out, 
a somewhat difficult operation. They clung very tenaciously to the fingers 
with exceedingly sharp claws, but, when thrown into the air, immediately flew 
off with a strong swinging flight. A single bud flew' from the second nest 
discovered, which was two feet down in a horizontal crack, and was similar in 
all respects to the first nest, and contained three eggs. The eggs of the Micropus 
pacificus are typical Swifts’ eggs—pure wdiite in colour and elongated in shape. 
Three apparently new nests were found close to each other in the same cranny, 
a long narrow aperture between two boulders. The remaining two nests were 
adjacent but separated, the whole area for the purpose being very restricted. 
“ The rock was again visited five days later. All the nests now contained 
eggs, three of them one apiece only. No other nests beside that previously 
mentioned contained three eggs. One additional nest was discovered con¬ 
taining two eggs ; this made eight nests in all. A Swift w r as found on each nest, 
but both birds at only two nests. Three Swifts made their appearance when 
the rock was approached on the later occasion, and continued to fly round 
during the visit.” 
The same writer in the Emu, says :—“ In the Bay of Kiaochau, whilst lying 
off an island of considerable size, myriads of these Swifts were observed on one 
of the last days of August. It was evidently a resort and breeding-place of 
much importance. The evening air was alive with them, and over and round 
the island they flew in every direction, twisting and wiieeling like a giant swarm 
of bees. The screams, however, were inconsiderable, and this appears to be a 
marked distinction between Gypselus pacificus and the familiar European bird. 
“ Time, and above all, the very pressing circumstances of the occasion 
(the exigencies of the Great War) prevented any closer acquaintance than 
could be gained from this wonderful and enjoyable sight.”

SPINE-TAILED SWIFT. 
In the Emu, Vol. XXIX., p. 308, April 1st, 1930, Mr. A. G. Campbell has 
the following very interesting note of a Spine-tailed Swift. 
“ A bird struck a telephone wire and was found clinging to a tree, apparently 
unhurt. It w r as able to run up the tree with great agility ; progressing, not oy 
hopping, as a Tree-Creeper does, but by rapid steps. The feet are very
