Trachycomus ochrocephalus, Gm. 
(The Yellow-crowned Bulbul.) 
Common, especially in gardens and along the banks of 
rivers ; it however keeps very well hidden as a rule, but 
its irresponsible whistling babble is very common, and a 
very liquid note. I saw great numbers of these along the 
banks of the Sadong river in May, 1912. Feet, tarsus, and 
claws black. The Malays call it “ Burong boya.” Oil- 
gland bare ; iris brick red. 
Pycnonotus analis, Horsf. 
(. Horsfield’s Bulbul.) 
One of the commonest birds in Upper Sarawak, as it is 
all over the country, and does a good deal of harm by eat¬ 
ing pepper here. The feathers on the back of the head are 
erected when the bird is excited or surprised. Great 
numbers of these Bulbuls are often seen roosting together 
in low jungle, usually in a marsh, and making a great 
noise with their harsh bickerings. The flight is undulating. 
The iris is deep brown. 
Hydrocichla ruficapilla, Temm. 
(The Bed-headed Fork-tail.) 
The feet and tarsus are pale yellow, so as to be almost 
white. Oil-gland bare ; iris dark brown. 
ClTTOCINGLA SUAVIS, Scl. 
(The Long-tailed Thrush.) 
Fairly common; strictly a jungle bird, and keeps to the 
lower branches of trees, flitting and flying about like 
Copsycus musieus. The song is like that of a Thrush and 
very sweet, chiefly heard in the evening. It is a Dayak 
omen bird, almost always seen solitary. The iris is black 
or dark brown; the tail is inclined to fork outwards; tarsus, 
feet and claws pale brown ; food—insects and seeds. 
Orthotomus cineraseus, Blyth. 
(The Ashy Tailor-bird.) 
Found in lalang and low jungle, where it clambers about, 
making a curious bleating noise; iris yellowish brown ; 
very plentiful. A female shot at Bau (Dec. 5th, 1911) had 
well-developed ovaries. The bill is brown, lighter coloured
