Martin-chasseur sacré

Identification

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).

Taxonomie

The binomial name Halcyon sanctus was introduced by Nicholas Aylward Vigors and Thomas Horsfield in 1827 who described a sacred kingfisher zoological specimen from New Holland, Australia. Vigors and Horsfield compare it with Alcedo sacra described by Johann Friedrich Gmelin in 1788. Gmelin in turn based his description on John Latham's "Sacred King's Fisher" published in 1782. Latham described several varieties, one of which was illustrated in Arthur Phillip's The Voyage of Governor Phillip to Botany Bay published in 1789. The genus Halcyon was split and the sacred kingfisher was placed in the genus Todiramphus that had been erected by the French surgeon and naturalist René Lesson in 1827. The generic name is derived from the genus Todus (Brisson, 1760), 'tody' (a West Indian insectivorous bird) and Ancient Greek rhamphos (ῥάμφος), 'bill'. The specific epithet is the Latin sanctus 'sacred'.<p>Five subspecies are recognised:<p>The holotype of Halcyon norfolkiensis Tristram is an adult male held in the vertebrate zoology collection of National Museums Liverpool at World Museum, with accession number NML-VZ T6527. The specimen was collected in Norfolk Island in October 1879 by E. L. Layard and came to the Liverpool national collection through the purchase of Canon Henry Baker Tristram's collection by the museum in 1896.

Répartition et habitat

Sacred kingfishers are found 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.<p>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.
