Main Article Content
Pigment disorders such as albinism, leucism and progressive greying, which cause the absence of melanin pigments in all or parts of the plumage and bare parts, have been reported in many wild bird populations including Acrocephalus warblers. Basra Reed Warbler Acrocephalus griseldis (Hartlaub, 1891) is a restricted-range species confined to the extensive reed beds of Mesopotamian marshes. It is listed as Endangered due to breeding habitat degradation, water scarcity and climate change. In April 2018, a partly white plumaged Basra Reed Warbler was sighted in Central Marshes in southern Iraq. This is the first report of such a plumage aberration in this species. The nature of the aberration involved an intraspecific/interspecific behavior of the white plumaged Basra Reed Warbler are described.
