804. Acrocephalus orinus

(804) Acrocephalus orinus Oberholser.
THE LARGE-BILLED REED-WARBLER.
Acrocephalus orinus, Fauna B. I., Birds, 2nd ed. vol. ii, p. 398.
There is really nothing known about the nidification of this bird, which has been obtained, a single specimen, in the Sutlej Valley.
Two eggs and a nest were sent to me by Captain Ellerton, taken on the 22nd May in the Sutlej Valley, which he believed to have been of this species, but the bird, after he thought he had identified it, was thrown away !
The nest, a typical Reed-Warbler’s, like that of brunnescens, “was placed in among the reeds growing on a submerged bank of the Sutlej ; in shape it was a very deep cup of soft strips of rushes and reed-leaves, strengthened and lined with fine grasses and grass-stems. It was attached to three or four of the reeds.”
It contained two eggs of the brown amyoe type of egg of stentoreus, which measured 21.9 x 15.6 and 22.0 x 16.0 mm.
The eggs are undoubtedly Reed-Warblers’ of some sort, but it is, of course, doubtful if they were properly identified as being the eggs of this extremely rare bird.
