Eastern Olivaceous Warblers are small warblers. Their entire plumage is inconspicuous. The lores, supercilia and front are grey with a buff tint, the crown and back are brownish-grey. The dark-grey flight feathers and outer tail feathers have light-grey edge lining. The irises are dark. The long, slender bill is dark-greyish on top and more brownish on the sides and underside. The legs and feet are greyish.

Eastern Olivaceous Warblers are no longer considered to be conspecific with the Western Olivaceous Warbler of northern Africa, together with which they were called "Olivaceous Warbler".

The overall distribution of this species can be assessed, and specific locations where birds have been spotted can be found, based on individual sighting reports submitted by birdwatchers to ebird.org .

The Eastern Olivaceous Warbler is a migratory species. Their breeding grounds range from eastern Europe via Asia Minor into parts of the Middle East and south-western Asia. They spend the northern winters in parts of Arabia or in sub-Saharan and tropical eastern Africa.

During their migration they can be found in parts of Arabia, including northern Oman. Some birds stay in Arabia during the winter months.

During their migration Eastern Olivaceous Warblers can be found in semi-desert country and wadis dominated by acacias, where they can often be seen hunting insects in those shrubs.

An Eastern Olivaceous Warbler was spotted by us on the Campus of Sultan Qaboos University, near Muscat, in April 2010.
