Common Hoopoe

Hoopoes are colourful birds found across Africa, Asia, and Europe, notable for their distinctive "crown" of feathers which can be raised or lowered at will. Two living and one extinct species are recognized, though for many years both extant species were lumped as a single species—Upupa epops. In fact, some taxonomists still consider the species to be conspecific. On the other hand, some authorities recognize three living species, with the African hoopoe treated as separate from the Eurasian hoopoe. The Eurasian hoopoe is common in its range and has a large population, so it is evaluated as Least Concern on the IUCN Red List of Threatened Species. However, their numbers are declining in Western Europe. Conversely, the hoopoe has been increasing in numbers at the tip of the South Sinai, Sharm el-Sheikh. There are dozens of nesting pairs that remain resident all year round.
