Sacred Kingfisher

The sacred kingfisher is mostly blue-green to turquoise above with white underparts and collar feathers, a black mask and buff lores. Both sexes are similar, but females are usually greener, duller and less buff beneath, and juveniles have buff or mottled brown edges on the collar, underparts and upper-wing coverts. Adults are 20–23 cm (7.9–9.1 in) long. Males weigh 28–61 g (1.0–2.2 oz) and females 28–56 g (1.0–2.0 oz).

The sacred kingfisher is distributed in Australia, New Zealand, Lord Howe Island, Norfolk Island, New Guinea, eastern Indonesia, much of northern and western Melanesia, and the Kermadec Islands. This species breeds throughout much of Australia (except the dry interior), New Zealand, New Caledonia and locally, New Guinea. Populations in the southern two-thirds of Australia migrate northwards at the end of the breeding season to New Guinea, east to the eastern Solomon Islands and west to Indonesia becoming uncommon to very sparse westwards to Sumatra. Birds move south again to Australia in August and September. It has also occurred as a vagrant on Christmas Island in the Indian Ocean, Malaysia, the Marshall Islands, the Federated States of Micronesia, and Nauru. A pair were spotted in Pampanga, Philippines in April / May 2016. In Australia, it inhabits open eucalypt forests, melaleuca swamps, mangroves, mudflats, wetlands and river or lake margins, farmland, parks and gardens. In New Zealand, T. sanctus vagans shows altitudinal migration, with post-breeding movement from higher altitudes to the coast and also from forest to coast and open lands.

The sacred kingfisher feeds on a wide variety of invertebrates (particularly insects and spiders), small crustaceans, fish (infrequently), frogs, small rodents and reptiles, and there are a few reports of them eating finches and other small birds. Usually, the sacred kingfisher will sit on a low branch and wait for prey to pass by. It swoops down to grab the prey by briefly landing (sally-pounce) or hovering (sally-strike), and then returns to its perch to eat its catch by beating and swallowing.

The name "sacred kingfisher" can be traced back to Latham's 1782 description of the species and what he called the "Respected Kingsfisher" of the Friendly Isles (now Tonga), and the "Venerated Kingsfisher" of the Society Islands (both collared kingfishers). Latham claims, citing Parkinson's journals, that all three kingfishers were held in "superstitious veneration" by the natives on account of frequently inhabiting marae and burial grounds, and were not allowed to be taken or killed. Later sources claim Polynesians venerated it for having the power of control over the waves.
