The reef heron, Egretta sacra, is found in tropical parts of eastern Asia, Australia and the Pacific Islands. Because it prefers the tropics, members of the New Zealand population of 300-500 birds is more often seen in the north of the North Island, although they do venture down south. There are two morphs of the reef heron, a dark morph like this one photographed at Motuareronui / Adele Island in the Abel Tasman National Park, and a light morph that is completely white. The New Zealand population is made up of dark morphs, and there is only one recorded sighting of a light morph in New Zealand, from the Avon-Heathcote Estuary in Christchurch, back in 1987. Reef herons are slightly smaller than the more common white-faced herons.
The pūkeko (Porphyrio melanotus melanotus) is common in the southwest Pacific and in Australia, they’re called the Australasian swamphen. The genus name, Porphyrio, is Latin for purple, and Porphyrio melanotus is regarded as a member of the “Purple swamphen complex”, a half a dozen similar that are found in southern Europe, Africa and Asia. They’re all about chicken-sized, with the chunky beak and red frontal shield of this guy and are, by and large, more blue than purple. Before anyone goes thinking too much down the chicken path, bear in mind that the traditional recipe is to cook them in a pot of water with a gumboot for several days before discarding the pūkeko and eating the gumboot.
The silvereye (Zosterops lateralis) first appeared in New Zealand in the 1830s and became more common in the late 1800s. They’re common in Australia, and presumably the first silvereyes in New Zealand were blown across the Tasman in storms. They’re also called wax-eyes and white-eyes, and their Māori name is tauhou, meaning “new arrival”. This silvereye is sitting on a bottlebrush (Callistemon) bush.
It’s more usual to see white-faced herons (Egretta novaehollandiae) in parks and paddocks after rain or on the estuary looking for food. In this photo taken during the summer, this young heron is checking out the local landscape from the very top of a tall tree. The lack of a white face gives away its juvenile status.
