Genus Hippolais

Booted Warbler - The Booted Warbler is an Old World warbler in the tree warbler group. It was formerly considered to be conspecific with Sykes' Warbler, but the two are now usually both afforded species status. Booted Warbler itself breeds from central Russia to western China, and migrates to winter in the Indian subcontinent as far south as Sri Lanka. It is a small passerine bird, found in open country with bushes and other tall vegetation. 3-4 eggs are laid in a nest in a bush or vegetation. Like most warblers they are insectivorous.

Icterine Warbler - This small passerine bird is a species found in open deciduous woodland with bushes and also parks and gardens, often near water. Four to six eggs are laid in a nest in a tree or a bush.

Upcher's Warbler - This small passerine bird is a species found in semi-desert habitats, frequenting bushy scrub and thickets of tamarisk. 4-5 eggs are laid in a nest in bushes and low trees.

Olive-tree Warbler - This small passerine bird is a species found in open-canopy oakwoods, olive groves, orchards and almond plantations. 3-4 eggs are laid in a nest in a low tree or a bush.

Hippolais opaca - It is a small passerine bird, found in dry open country, including cultivation, with bushes or some trees. 2-3 eggs are laid in a nest in low in undergrowth or a bush. Like most warblers, Western Olivaceous is insectivorous.

Olivaceous Warbler - Olivaceous Warbler can refer to one of two bird species, formerly regarded as conspecific:

Melodious Warbler - This small passerine bird is a species found in open woodland with bushes. 3-5 eggs are laid in a nest in a tree or a bush.

Sykes's Warbler - Sykes' Warbler is an Old World warbler in the tree warbler. It was formerly considered a subspecies of the Booted Warbler, but is now considered a full species. Its breeding range is from northeast Arabia to Afghanistan. Like the Booted Warbler, many populations of the species migrate in winter to the Indian subcontinent as far south as Sri Lanka.
