'''Common Name:''' Grey Heron<br>

'''Scientific Name:''' Ardea cinerea

'''Habitat:''' Europe, Asia & Africa; throughout temperate Europe and Asia and also parts of Africa. Prefers habitat is shallow water, relatively large prey, and four or five months of ice-free breeding.

-

'''Status:''' Least Concern. Global population: 790,000 - 3,700,000. In Europe the species was heavily persecuted in the nineteenth century due to its consumption of fish, which resulted in competition with fishermen and fish farmers. Although killing at aquaculture farms has not reduced the global population so far (possibly because it is young birds that are mostly killed), 800 herons are estimated to have died per year at Scottish fish-farms between 1984 and 1987, 5 by being shot, drowned or poisoned by fish farmers. Renewed hunting poses a threat to Bavarian populations by decreasing numbers to levels that inhibit recovery following severe winters (severe winters increase mortality rates for juveniles). The species is vulnerable in Madagascar owing to its restricted range, exceedingly high levels of habitat alteration (from siltation and the need for agricultural land for rice and grazing), hunting, and predation at nesting colonies. Timber harvesting is a threat throughout much of the species range by removing trees used by nesting colonies and/or disturbing nearby colonies. The species is also susceptible to avian influenza and avian botulism, so may be threatened by future outbreaks of these diseases. It is protected by the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA).

'''Diet:''' Fish, frogs, and insects with its long bill. Herons will also take small mammals (even small rabbits), reptiles and occasionally warbler nestlings, plovers, snipes, ducklings and tern chicks and other small birds.

* ''Ardea cinerea monicae''. Jouanin & Roux, 1963. Islands off Banc d'Arguin, Mauritania.
