The Booted Warbler, Hippolais caligata, is an Old World warbler in the tree warbler genus Hippolais. It was formerly considered a single species, but is now usually considered as two forms with species status. These are the Booted Warbler itself, which breeds from central Russia to western China, and the Sykes' Warbler, Hippolais rama, breeding from northeast Arabia to Afghanistan. Both populations migrate to winter in the Indian subcontinent south to Sri Lanka.
These small passerine birds are 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, these are insectivorous.
These are small warblers, especially compared to others in their genus. They are pale brown (weak tea) above and whitish below with buff flanks. The outer tail feathers have pale edges. They have a short pale supercilium, and the bill is strong and pointed. The Sykes' is larger and greyer than the Booted, and most resembles an Eastern Olivaceous Warbler.
