Matuku moana - reef heron - Egretta sacra

Nationally endangered,

Photographed at Ligar Bay, Takaka, New Zealand.

 

The reef heron is a dark grey wading bird most often seen in coastal areas in the north of the North Island. One or two birds may be found patrolling a rocky shoreline or nearby estuary. Although similar to the common white-faced heron it is not seen as frequently and has slightly different feeding habits. Reef herons occur throughout Polynesia, and their prevalence in northern New Zealand may reflect their preference for warmer climates.

 

The dark grey colour provides the bird with excellent camouflage when it is patrolling the shoreline rocks that are its main habitat. The reef heron is wary, and flies away when approached too closely. It will, however, use man-made structures for nesting.

Reef herons are widely distributed through eastern Asia, the tropical Pacific islands, Australia and New Zealand. Elsewhere there are two colour morphs, white and grey, with birds in intermediate plumage occurring also. Only the grey morph breeds in New Zealand, but there has been a single record of a white bird, at the Avon-Heathcote Estuary, Christchurch, in June 1987. Typical grey birds may be seen in the North, South, Stewart and some offshore islands, with more birds found in northern areas. www.nzbirdsonline.org.nz
