In many respects intermediate between Eastern Olivaceous Warbler and Booted Warbler and was previously considered conspecific with the latter. Differentiated from Booted by marginally larger size, more whitish below, greyish above, shorter wings and longer tail and flatter crown. It rarely shows darker toes like Booted.
Smaller than Eastern Olivaceous Warbler (though with some overlap) and shorter-winged; also differs in behaviour, flicking both tail and wings nervously like Booted but not making the steady tail-dipping movements of Eastern Olivaceous.
Could also be confused with Blyth's Reed Warbler, which has rounded tail without white outer tail feathers.
Open country with bushes and other tall vegetation. Winters in scrub and groves in dry habitat. Breeds in waterside reeds.
The clutch consists of 3-4 eggs which are laid in a nest in a bush or vegetation.
Their diet consists mostly of insects and spiders, with the addition of caterpillars in the breeding season. There is little extra information available.
