The Grasshopper Warbler (Calamodyta locustella), a member of the Dentirostral (tooth-billed) Insessores, family Lusinidae (nightingale kind) and sub-family Luscininae, is of a greenish-brown colour, the upper parts being pale brown. Its length is about 5½ in. It keeps so close to a hedge that it is difficult to catch a glimpse of it, but the incessant cry, closely resembling a grasshopper, reveals its whereabouts. The nest is carefully concealed, and composed of dried grass, etc. The eggs are from five to seven in number, white speckled with red. The food consists of insects. It arrives in Britain in April and departs in September.
The Sedge Warbler (Calamodyta phragmitis) dives into reeds and grasses when disturbed. Its colour is brown above and white on the throat, the abdomen being of a buff colour. It frequents river-sides, osier-beds, etc. The average length is 4½ in. The eggs number four or five, yellowish-brown, with darker brown spots. The food consists of insects. It arrives in this country in April and leaves it in September.
