Reef heron - photographer: Ian SoutheyThe reef heron occurs in grey and white forms, but only the grey phase occurs in New Zealand. This slate-grey heron has a long heavy horn-coloured to yellowish bill and short yellow-green legs. In the breeding season, long plumes form on the neck and back.  The call is a guttural croak when disturbed or at the nest.

The Reef Heron eats mainly small fish, including eels and flounder, crabs and molluscs caught along rocky shores and tidal inlets where they live.

Breeding takes place between September and January. The nest, which is a platform of sticks and twigs, is built on rock ledges in caves or rock crevices, in clumps of flax or among the roots of pohutukawa. The two to four pale turquoise coloured eggs are incubated by both sexes for 25-28 days. Chicks fledge when 5-6 weeks old.

Reef Heron are decreasing in numbers due to increased human disturbance on the coast.  They are seen on the rocks around Tiritiri and have been known to nest on the Island, including the 2013-2014 season when two chicks were raised.
