4-61 to 4-35 inches, tail 3-25 to 2-95 inches, culmen 0-91 to 0-81 inch, tarsus 1-35 inch; bastard-
primary projecting beyond the primary-coverts, its exposed portion measuring 1’05 to 0-95 inch.
Young in first plumage. Probably have pale shaft-streaks to all the small feathers of the upper
parts, except the wing-coverts. An example in the British Museum still retains the pale shaft-streaks
on the scapulars; the black on the throat is confined to two malar stripes, and the breast and flanks
are much suflused with rufous.
The female probably resembles the male in colour.
The figure represents the type in the British Museum, and is life-sized. The same example
was figured in 1872 by the late Marquis of Tweeddale (Trans. Zool. Soc. viii. pi. 6. fig. 2).
