(436) Pycnonotus plumosus blanfordi.
Blanford's Olive Bulbul.
Pycnonotus blanfordi Jerdon, Ibis, 1862, p. 20 (Pegu) ; Blanf. & Oates, i, p. 291.
Vernacular names. Byw, Bo-sa-mwe (Burmese); Bo-sa-mwe (Kachin).
Description. Differs from Robinson's Olive Bulbul in being much paler and with ear-coverts wholly silvery-white. It is much less green both on upper plumage and on wings and tail than plumosus.
Colours of soft parts. Iris varies from yellowish brown to red; eyelids plumbeous; bill brown, paler at base of lower mandible and gape; mouth flesh-colour; legs plumbeous, claws horn-colour.
Measurements as in the other races. Wing 85 to 89 mm.; culmen about 15 mm.
Distribution. Practically the whole of Burma, North of Ran¬goon, the Kachin Hills, North and Central Siam, Shan States and Annam.
Nidification. Similar in every way to that of the last bird. Eggs and nests are indistinguishable and the clutches are the same in number, i. e. two or three. As a series they are even more poorly marked than those of Robinson's Olive Bulbul. Forty eggs average 20.6 x 15.7 mm.
The breeding season must be very extended, as eggs have been sent me taken from early March to late August and, probably, like most of the common Bulbuls, they breed more or less throughout the year.
Habits. Those of the last bird. They are said to have a very harsh note when disturbed and like all Bulbuls under these circumstances, erect their crests as they make the call.
