(802) Acrocephalus agricola haringtoni Witherby.
THE KHAGAN VALLEY PADDY-FIELD WARBLER.
Acrocephalus concinens haringtoni, Fauna B. I., Birds, 2nd ed. vol. ii, p. 396.
Up to now this little Reed-Warbler has been known to breed only on the extreme North-West Frontier, where nests were taken by Whitehead and Harington. Whether the nests built in bushes in Kashmir belonged to this bird or whether they were merely aberrant nests of the Kashmir race cannot be decided until birds are shot off similar nests and identified.
Whitehead found this bird breeding in the Khagan Valley in 1912 and sent specimens to Hartert, Ticehurst and myself, who, curiously enough, all independently identified the bird as concinens, the Chinese bird. Later, however, Witherby pointed out the differences and gave it the name of haringtoni, after Harington, who again found the bird breeding in almost the same area.
Whitehead writes (Journ. Bomb. Nat. Hist. Soc. vol. xxiii, p. 106, 1914):—“Many stay to nest in the Khagan. Unlike typical agricola, it nests in undergrowth (Kamila) on the hill-side far from water. It starts nesting at the end of June ; 7 nests were found in all. Both nests and eggs resemble those of A. stentoreus but the nest is much neater and built within a few inches of the ground. It is usually woven round four stalks (in one case three) in true Reed-Warbler fashion, composed of stems and grass, neatly lined with roots, and in some cases with an edging of green grass woven round the top of the cup.
“The cock bird at this season throws off his skulking habits and may generally be seen in a conspicuous position singing his high-pitched squeaky song, accompanied by much craning of the neck and erecting of the feathers of his crown.”
The three clutches of eggs taken by Whitehead, and now in my collection, were taken from nests of which two were “attached to four nettle stalks” and the third to “Janala stems.”
Three seems to be the invariably full clutch.
All the eggs in my collection, both Harington’s and Whitehead’s, were taken between the 7th and 23rd July, but some of the latter’s “7 nests” were taken in the end of June.
The eggs cannot be distinguished from those of the Kashmir lake-breeding bird.
Twelve eggs average 17.7 x 12.8 mm. : maxima. 18.5 x 12.8 and 18.0 x 13.1 mm. ; minima 17.0 x 12.3 mm.
