Description
These 13–14 cm long warblers have short rounded wings and longish graduated cream tail tipped with black subterminal spots. The tail is usually held upright and the strong legs are used for clambering about and hopping on the ground. They have a short black bill. The crown is grey and the underparts are rufous in most plumages. In breeding plumage, adults of the northern population are ash grey above, with a black crown and cheek with no supercilium and rufescent wings. In non-breeding season, this population has a short and narrow white supercilium and the tail is longer. They are found singly or in pairs in shrubbery and will often visit the ground.
In winter, the northern subspecies, P. s. stewartii Blyth, 1847, has warm brown upperparts and a longer tail and has seasonal variation in plumage. The other races retain summer plumage all year round. West Bengal and eastwards has race inglisi Whistler & Kinnear, 1933 which is darker slaty above than the nominate race of the Peninsula and deeper rufous on the flanks with a finer and shorter beak. The distinctive endemic race in Sri Lanka, P. s. brevicauda Legge, 1879, has a shorter tail and has the juveniles with yellowish underparts apart from a distinct call.

Famous quotes containing the word description:
“Everything to which we concede existence is a posit from the standpoint of a description of the theory-building process, and simultaneously real from the standpoint of the theory that is being built. Nor let us look down on the standpoint of the theory as make-believe; for we can never do better than occupy the standpoint of some theory or other, the best we can muster at the time.”
—Willard Van Orman Quine (b. 1908)
“To give an accurate description of what has never occurred is not merely the proper occupation of the historian, but the inalienable privilege of any man of parts and culture.”
—Oscar Wilde (1854–1900)
“As they are not seen on their way down the streams, it is thought by fishermen that they never return, but waste away and die, clinging to rocks and stumps of trees for an indefinite period; a tragic feature in the scenery of the river bottoms worthy to be remembered with Shakespeare’s description of the sea-floor.”
—Henry David Thoreau (1817–1862)
