Lesser whitethroat bird is a smallish and compact warbler with dull grey-brown upperparts, dark grey ear coverts that contrast with a grey head, and a shortish grey-brown tail with white outer tail feathers. The wing is plain and without any rufous or pale panels. The underparts of lesser whitethroat bird are dull whitish, washed browner on the sides. The bill is fairly short, grey with a paler base, and the legs are dark grey. A little more secretive than the Common Whitethroat, the best indicator is its voice.
Lesser whitethroat bird is a summer visitor, favouring taller vegetation than the Common Whitethroat and found mainly in bushy areas between woodland and open country, such as in mature farmland hedgerows, heath-land, plantations, well-grown gardens, parks and cemeteries, woodland edge and clearings, scrub and thickets.
The call of lesser whitethroat bird is a hard and dry, tongue-clicking "tekk" or "thekk", often repeated freely. Lesser whitethroat bird also has a hoarse, grating churr, and an alarmed rattle similar to that of the Wren. The song is a distinctive hard wooden rattling, reminiscent of part of the song of the Chaffinch, and is made up of 6-12 double notes at a rate of roughly 10 per second, a "djeh'djeh'djeh'djeh'djeh'djeh". This is typically preceded by a weak and subdued warbling of varying length, longer variants sounding similar to the warbling of the Blackcap or Common Whitethroat. It starts quietly and builds up in volume to the louder rattle part, and is often audible only at close range. It can sometimes deliver these two parts of the song separately. There seems to be quite a variation in songs regionally, birds in Europe often sounding rather different from those in Britain.
