Nycticorax nycticorax:
Bird

IUCN Status
Listed as a species of “Least concern” they are abundant and common throughout their vast range.



Diet

Small fish, crustaceans, frogs, aquatic insects, mammals and small birds. This like other herons is an opportunistic feeder.

Habitat

Virtually all wetlands in the Tropics and warmer temperate climates.

Behaviour

A waterside ambush predator and colony nester particularly crepuscular in activity!

Breeding

Colony nester where 3 – 5 greenish eggs are laid in a typical heronry on stick platforms in groups of trees or protected reed beds!

Fun Facts

The Latin Nycticorax means night raven (referring to its harsh “crow-like” call often head at night)!

During breeding adult birds develop 2 or 3 long white head plume feathers.

In the USA the northern most birds migrate for summer breeding returning to Mexico to over-winter. Most of the Northern European birds are sedentary.

At The Zoo

Our colony of black crowned night herons consistently breed each year. The chicks as they grow are a camouflaged brown but have the most delightful” quiff which they throw about when squabbling amongst themselves! From May onwards the young chicks in the nest can be heard calling for food from their parents in the bottom half of the zoo (enclosure 32)!
