Hypocolius

The grey hypocolius, also known simply as hypocolius (Hypocolius ampelinus), is a unique small passerine bird that stands alone in its genus and family, Hypocoliidae. It inhabits dry semi-desert regions from northern Africa to western India, including the Middle East, and is known to migrate southward during winter. This slender bird, approximately 19–21 cm in length, shares similarities with waxwings, bearing a long tail, a slight crest, and soft, grey or brownish-grey plumage. Males are distinguished by a black eye mask and both sexes have distinctive white-tipped wings and a black-banded tail. Not particularly expressive, they raise their head feathers when excited and have a straight, non-undulating flight pattern. Once unclear, their taxonomical relationships now place them close to waxwings and other bird groups like silky-flycatchers. They are shy, often found in flocks, and forage mainly on fruits such as mulberries, figs, and dates, while also partaking in insects occasionally. Their calls include a series of descending notes, and they breed in the summer, building cup-shaped nests in trees and laying four eggs. Despite being of interest to birdwatchers due to its unique status, the grey hypocolius is currently not at risk and is classified as a species of "least concern" by IUCN standards.
