Purple Heron
Ardea purpurea (Linnaeus, 1766)
UR
PURHE
1240
Family: Pelecaniformes > Ardeidae
With its warm buff head and neck, black cap, grey back and deep chestnut shoulder patch, the adult Purple Heron is a smart bird, but one that favours the dense vegetation, such as reedbeds, of shallow waterbodies.
Purple Heron is considered an occasional breeder, and one for which proving breeding can be difficult. Its European breeding population has been expanding since at least the 1940s, with colonisation of France and the Netherlands signposting this species as a potential colonist to Britain & Ireland.
