In Asia and Australia, great Egret are widespread and abundant, but in New Zealand - where they are known as kōtuku (white heron) - they are birds of great rarity with a conservation status of "nationally critical" and a population of maybe 150 to 200 birds.
Their sole New Zealand breeding site is near Okarito Lagoon in Westland (South Island), where every kōtuku in NZ goes to breed. Outside of the breeding season, these birds disperse widely throughout NZ, preferring to be alone, and fiercely defending their wintering-over sites against other kōtuku.
No wonder, then, that in most of New Zealand, the bird is known as 'He kōtuku rerenga tahi' or "the bird of single flight", implying something seen perhaps once in a lifetime.
It is during this wintering over season that most New Zealanders stand their best chance of seeing one of these birds in their local area.
This photo was taken of a kōtuku in early morning mist at Te Roto o Wairewa/Lake Forsyth, less than five minute's drive from Auldwood Birds' office. The bird was roosting in amongst a dense grove of bare winter willows, so finding a "window" to get this photo, took time and some gentle, quite, manoeuvres.
Auldwood Birds offers "winter white heron tours" for Canterbury locals or visitors wanting to find this elusive bird.
