Grasshopper Warbler

Identification of Grasshopper Warbler

Grasshoper Warbler Bird 1 Length: 12.5-13.5cm Wingspan: 15-19cm Call: "pjitt"

Grasshopper bird is a small and demurely plumaged warbler, with a fine bill, short wings and fairly long graduated tail. Grasshopper bird lacks any bold face pattern, with just a narrow pale line over the eye, and has diffuse dark streaking on the upperparts and dark-centred wing coverts and tertials. The upperparts are dull olive-brown overall, while the underparts are whitish, washed olive-buff on the breast and flanks, it is normally unstreaked below, although some may show dark flecking on the throat and upper breast. The long undertail coverts show diffuse streaking.

Habitat of Grasshopper Warbler Bird

Grasshopper bird is a summer visitor, favouring low, tangled vegetation such as overgrown thickets, meadows, nettlebeds, grass, and the drier parts of reedbeds, particularly where there are scattered bushes, or in young trees such as conifer plantations. It is often found in damp areas or near water, marshes, lakesides and small watercourses. Often scuttles along the ground like a mouse and is very hard to spot unless singing, and so is rarely seen on migration.

Song / Call of Grasshopper Warbler Bird

The song of grasshopper bird is very distinctive, a continuous and thin insect-like trilling or 'reeling' like a free-wheeling bicycle, which can continue for many minutes and is frequently heard in the evenings or at night. The song often begins with some shorter 'practice' bursts before the main effort, and actually consists of double notes that are delivered at a rate of 24-26 per second at frequency of around 6kHz. Grasshopper bird is usually sung from within a small bush or low in grass or reeds, where the bird can sometimes be found sitting with bill open and orange gape showing, turning its head from side to side. This action causes the sound to be 'thrown', and the volume rises and falls, depending on where the bird is facing. The call is a short sharp "pjitt" or "thsik", and short, sub-song-like ticking sounds are also given.
