The Sykes's warbler (Iduna rama), a member of the tree warbler family, is a small passerine that presents a pale brown upper body and a whitish underside with buff flanks. Notably, the outer tail feathers are edged with pale coloration. A short pale supercilium graces its face, and it possesses a strong, pointed bill. This species is larger and greyer than its relative, the booted warbler, and bears a close resemblance to the eastern olivaceous warbler.
When attempting to identify Sykes's warbler, look for its pale brown upper parts and whitish underparts with buff flanks. The bird's short pale supercilium and strong, pointed bill are also key characteristics. Its size, larger and greyer than the booted warbler, can help distinguish it from similar species.
Sykes's warbler is found in open country with an abundance of bushes and tall vegetation. It is here that it establishes its territory and seeks out suitable nesting sites.
The breeding range of Sykes's warbler spans from northeast Arabia to Turkestan, western China, and Afghanistan. During the winter months, many populations migrate to the Indian subcontinent, reaching as far south as Sri Lanka.
This warbler is known for its insectivorous habits, foraging in its open country habitat. It is also observed defending its territory from other birds such as the Lesser Whitethroat.
Sykes's warbler lays three or four eggs in a nest situated within a bush or amidst tall vegetation. The nesting and egg morphology of this species show distinct differences from those of the booted warbler.
The Sykes's warbler is most similar in appearance to the eastern olivaceous warbler but can be differentiated by its larger size and greyer coloration.
As an insectivorous bird, Sykes's warbler primarily feeds on insects, which it actively seeks out in its habitat of open country with bushes and tall vegetation.
The IUCN Red List categorizes Sykes's warbler as Least Concern, indicating that the species does not currently face any significant threats to its population.
