The eastern olivaceous warbler (Iduna pallida) is an Old World bird of the Acrocephalidae family. This bird has striking similarities with other Iduna and Acrocephalus species. It is recognized as a fairly common species throughout its range, therefore, is regarded as a stable species. However, the global population trend is unknown. In some areas, widespread habitat destruction has snatched away the bird's ideal nesting sites. Expansion of agricultural lands, forest destruction, and clearing bushes have made the warbler population a bit more restricted than before but they are not facing any major threats as of yet.

Based on the eastern olivaceous warbler range, they are divided into four different subspecies, each inhabiting different regions. These birds prefer to inhabit forest borders rather than interiors of the forest. The presence of water bodies near their habitat is not necessary, although the bird species favors the presence of a nearby water source. They use several plant matters like stems and twigs to build the breeding nest and line the nest with plants and fur. To know more amazing facts about the bird, keep on reading.
