Distribution. Breeding in Afghanistan and North Kashmir, in Winter South to Punjab and the N.W. Provinces as far East and South as Cawnpore.
Nidification. Whitehead found this bird breeding freely in the Safed Koh in June and July on the wooded slopes of the Kurram Valley between 7,000 and 9,000 feet. The nest was placed in the bank of a nullah under a bush and was domed, made of grass and lined with goats' hair. It contained three eggs, white spotted with red, measuring about 14.0 x 10.7 mm.
Habits. During the Summer this Willow-Warbler keeps much to undergrowth but during the Winter it is found more often in trees. It has the usual vivacious active habits of the genus. The call-note is said to be a monosyllabic " tweet,'" and the song is described by Mr. H. Whistler as " wet-wet-wet-weet-whir-r-r-r." It occurs in the months of October and March in the Punjab and North-West Provinces.
