The plumed egret (Ardea plumifera) is a species of heron native to Australia and Oceania. Previously this species was regarded as a subspecies of the intermediate egret (Ardea intermedia sensu lato ) alongside the Asian intermediate egret (A. (i.) intermedia) and the African yellow-billed egret (A. (i.) brachyrhyncha).

Taxonomy

The plumed egret was first formally described as Herodias plumiferus by the English ornithologist John Gould with its type locality given as New South Wales. [2] This taxon has been regarded as a subspecies of the intermediate egret (Ardea intermedia) but on 26 September 2023 the International Ornithological Congress recognised the three subspecies of A. intermedia as valid species. [3]

Description

The plumed egret is a medium-sized heron, 56 to 70 cm (22 to 28 in) in length with an all white plumage. In breeding plumage it develops long white frilly plumes from its breast and shoulders. In addition, the bill changes colour to red or orange with green lores and the tibia is red and the tarsus is black. Outside the breeding season the bill is yellow-orange with yellow lores and the legs are black. [4]

Distribution and habitat

The plumed egret is found in Australasia and breeds in eastern Indonesia, Timor-Leste, New Guinea and Australia, [5] with vagrants occurring in New Zealand and the Solomon Islands. [6] This species is found in the shallow water at the edges of freshwater wetlands and the intertidal zone. [4]

Biology

The plumed egret is diurnal, hunting in shallow water for fish, frogs, aquatic insects and crustaceans. In Australia this species breeds in late summer forming colonies in trees. They lay 3-5 pale bluish-green eggs which are incubated by the male and the female and take 24–27 days to hatch. The young fledge in 5 or 6 weeks. [7]

<span class="mw-page-title-main">Egret</span> Type of bird of the heron family

Egrets are herons, generally long-legged wading birds, that have white or buff plumage, developing fine plumes during the breeding season. Egrets are not a biologically distinct group from herons and have the same build.

<span class="mw-page-title-main">Great blue heron</span> Species of bird

The great blue heron is a large wading bird in the heron family Ardeidae, common near the shores of open water and in wetlands over most of North and Central America, as well as far northwestern South America, the Caribbean and the Galápagos Islands. It is occasionally found in the Azores and is a rare vagrant to Europe. An all-white population found in south Florida and the Florida Keys is known as the great white heron. Debate exists about whether this represents a white color morph of the great blue heron, a subspecies of it, or an entirely separate species.

<span class="mw-page-title-main">Heron</span> Family of birds

Herons are long-legged, long-necked, freshwater and coastal birds in the family Ardeidae, with 72 recognised species, some of which are referred to as egrets or bitterns rather than herons. Members of the genera Botaurus and Ixobrychus are referred to as bitterns, and, together with the zigzag heron, or zigzag bittern, in the monotypic genus Zebrilus, form a monophyletic group within the Ardeidae. Egrets do not form a biologically distinct group from herons, and tend to be named differently because they are mainly white or have decorative plumes in breeding plumage. Herons, by evolutionary adaptation, have long beaks.

<span class="mw-page-title-main">Grey heron</span> Long-legged predatory wading bird

The grey heron is a long-legged wading bird of the heron family, Ardeidae, native throughout temperate Europe and Asia, and also parts of Africa. It is resident in much of its range, but some populations from the more northern parts migrate southwards in autumn. A bird of wetland areas, it can be seen around lakes, rivers, ponds, marshes and on the sea coast. It feeds mostly on aquatic creatures which it catches after standing stationary beside or in the water, or stalking its prey through the shallows.

<span class="mw-page-title-main">Great egret</span> Species of bird

The great egret (Ardea alba), also known as the common egret, large egret, or great white egret or great white heron, is a large, widely distributed egret. The four subspecies are found in Asia, Africa, the Americas, and southern Europe. Recently it is also spreading to more northern areas of Europe. Distributed across most of the tropical and warmer temperate regions of the world, it builds tree nests in colonies close to water.

The black-crowned night-heron, or black-capped night-heron, commonly shortened to just night-heron in Eurasia, is a medium-sized heron found throughout a large part of the world, including parts of Europe, Asia, and North and South America. In Australasia it is replaced by the closely related nankeen night-heron, with which it has hybridized in the area of contact.

<span class="mw-page-title-main">Snowy egret</span> Species of bird

The snowy egret is a small white heron. The genus name comes from Provençal French for the little egret, aigrette, which is a diminutive of aigron, 'heron'. The species name thula is the Araucano term for the black-necked swan, applied to this species in error by Chilean naturalist Juan Ignacio Molina in 1782.

<span class="mw-page-title-main">Little egret</span> Species of water bird

The little egret is a species of small heron in the family Ardeidae. It is a white bird with a slender black beak, long black legs and, in the western race, yellow feet. As an aquatic bird, it feeds in shallow water and on land, consuming a variety of small creatures. It breeds colonially, often with other species of water birds, making a platform nest of sticks in a tree, bush or reed bed. A clutch of three to five bluish-green eggs is laid and incubated by both parents for about three weeks. The young fledge at about six weeks of age.

<span class="mw-page-title-main">Cattle egret</span> Cosmopolitan genus of heron

The cattle egret (Bubulcus) is a cosmopolitan genus of heron found in the tropics, subtropics, and warm-temperate zones. According to the IOC bird list, it contains two species, the western cattle egret and the eastern cattle egret, although some authorities regard them as a single species. Despite the similarities in plumage to the egrets of the genus Egretta, it is more closely related to the herons of Ardea. Originally native to parts of Asia, Africa, and Europe, it has undergone a rapid expansion in its distribution and successfully colonised much of the rest of the world in the last century.

<span class="mw-page-title-main">Western reef heron</span> Species of bird

The western reef heron, also called the western reef egret, is a medium-sized heron found in southern Europe, Africa and parts of Asia. It has a mainly coastal distribution and occurs in several plumage forms: a slaty-grey plumage in which it can only be confused with the rather uncommon dark morph of the Little egret ; a white form which can look very similar to the little egret although the bill tends to be paler and larger and the black form with white throat E. g. gularis of West Africa. There are also differences in size, structure and foraging behaviour. There have been suggestions that the species hybridizes with the Little Egret, and based on this, some authors treat schistacea and gularis as subspecies of Egretta garzetta. Works that consider the Western Reef Heron as a valid species include the nominate gularis and schistacea as subspecies.
