Nycticorax nycticorax (Linnaeus, 1758)
Family: Pelecaniformes > Ardeidae
With a wide breeding range that extends across much of Eurasia, this is a scarce visitor. While wild birds are typically seen in either April/May or October/November, free-flying birds from collections may also be encountered.
Young Black-crowned Night-Herons often disgorge their stomach contents when disturbed. This habit makes it easy to study their diet.
