Booted warbler description

GenusHippolais (1)

A relatively small bird compared to most other species of warbler, the booted warbler is rather dull in appearance. Both sexes are olive brown in colour with a whitish throat and abdomen, and a distinctive white line that runs along the head from the beak to just above the eye (4). The beak itself is short and pointed, making it ideal for gleaning insects (4). During the breeding season the booted warbler utters a sweet-sounding song (4), made up of a fast mix of chirrups and babbles (5).

Length: 11.5 - 12 cm (2)
Wingspan: 18 - 21 cm (2)
10 g (3)

Booted warbler biology

The booted warbler is often found moving in a restless manner through the undergrowth, or perched on branches (4). It feeds primarily on insects (3), but like other members of this genus it will also sometimes eat seeds and berries.

The breeding season of this species extends from the end of May to the beginning of July (2). The booted warbler constructs a cup-shaped nest from grass, bark, hair and string, with a soft lining of grass, feathers and cotton (4), which is typically placed in a bush fairly close to the ground (8). The booted warbler lays a clutch of between four and six eggs (2).


Booted warbler range

The breeding range of the booted warbler stretches from west and south-west Russia, eastwards to central and northern Kazakhstan, north-western Mongolia, north-west China and south-central Siberia. It migrates to India for the winter (6)


Booted warbler habitat

The booted warbler occupies relatively open areas of shrubland or grassland (7).
