Birds of Gazaland, Southern Rhodesia. 51 
vary from light golden brown to burnt-sienna; the legs are 
pale silvery grey, often with a fleshy tint ; the soles usually 
yellowish. 
53. PuytLostropHus FLAvisTRIATUS. Yellow-streaked 
Bulbul. 
This is the commonest Bulbul of the Chirinda forest, and, 
as I have shot it also in wooded kloofs and isolated forest- 
patches, I have little doubt that it will be found through- 
out the district in such situations. It may be seen during 
the winter, in fact from the end of February onwards, in 
parties of six or seven, searching the undergrowth, usually 
silently, or ascending the trunks of trees and saplings 
spirally and hunting for insects under the bark. While thus 
engaged it will repeatedly flap one wing, whether as an aid 
to balancing itself or in order to frighten out the insects I 
have been unable to ascertain. Dry leaves, or a broken 
branch caught up in the trees or undergrowth, are a great 
attraction, and are always carefully searched for what they 
may conceal; finally, when not actually engaged in gaining 
a livelihood, the birds may often be seen playfully chasing 
one another amongst the higher branches of the trees. 
They have several notes, the most frequently heard 
resembling the syllables “chip! chap! chop! chip-chap- 
chop!” or again, “chip! chap! chop! chip-chop-chap- 
charrap!” which, with slight variations, are repeated several 
times in succession. Apparently two broods are reared in 
the season, as I have found nests containing eggs from the 
commencement of November right on into February. They 
are attractively-built but somewhat fragile structures (see 
text-fig. 2, p. 52), slung sometimes from a horizontally- forked 
twig, but more usually from the broad glossy leaves, at their 
junction with the stem, of a handsome Dracena, which is 
common throughout the forest, from three to six feet from the 
ground, They are composed externally of a light frame-work 
of roots, tendrils, and one or two twigs or a little green moss, 
with a more solid bottom of dry leaves braced on by means of 
tendrils and roots, the whole being bound together with fine
