In flight in Kolkata, West Bengal, India

It is a fairly large species at 58 cm (23 in) in length, being by some margin the largest bittern in the genus Ixobrychus. Compared to related species, it has a longish neck and long yellow bill. The adult is uniformly black above, with yellow neck sides. It is whitish below, heavily streaked with brown. The juvenile is like the adult, but dark brown rather than black. They can be difficult to see, given their skulking lifestyle and reed bed habitat, but tend to fly fairly frequently when the all black upperparts makes them unmistakable.

Breeding

Their breeding habitat is reed beds. They nest on platforms of reeds in shrubs, or sometimes in trees. Three to five eggs are laid.

Diet

Black bitterns feed on insects, fish, and amphibians.

Conservation status

Australia

Black bitterns are not listed as threatened on the Australian Environment Protection and Biodiversity Conservation Act 1999.

<span class="mw-page-title-main">Bush stone-curlew</span> Species of bird

The bush stone-curlew or bush thick-knee is a large, ground-dwelling bird endemic to Australia. Its favoured habitat is open plains and woodlands, where it stalks slowly at night in search of invertebrates such as insects. Its grey-brown coloration is distinguished by dark streaks, its eyes are large and legs are long. It is capable of flight, but relies on the camouflage of its plumage to evade detection during the day; the bush curlew adopts a rigid posture when it becomes aware of an observer. Both sexes care for two eggs laid on the bare ground, usually sited near bush in a shaded position or next to a fallen branch.

The grey-tailed tattler, also known as the Siberian tattler or Polynesian tattler, is a small shorebird in the genus Tringa. The English name for the tattlers refers to their noisy call. The genus name Tringa is the Neo-Latin name given to the green sandpiper by Aldrovandus in 1599 based on Ancient Greek trungas, a thrush-sized, white-rumped, tail-bobbing wading bird mentioned by Aristotle. The specific brevipes is from Latin brevis, "short", and pes, "foot".

The magpie goose is the sole living representative species of the family Anseranatidae. This common waterbird is found in northern Australia and southern New Guinea. As the species is prone to wandering, especially when not breeding, it is sometimes recorded outside its core range. The species was once also widespread in southern Australia but disappeared from there largely due to the drainage of the wetlands where the birds once bred. Due to their importance to Aboriginal people as a seasonal food source, as subjects of recreational hunting, and as a tourist attraction, their expansive and stable presence in northern Australia has been "ensured [by] protective management".

The yellow bittern is a small bittern. It is of Old World origins, breeding in the northern Indian Subcontinent, east to the Russian Far East, Japan and Indonesia. It is mainly resident, but some northern birds migrate short distances. It has been recorded as a vagrant in Alaska and there is a single sighting in Great Britain, from Radipole Lake, Dorset on November 23, 1962 – however, the British Ornithologists' Union has always considered this occurrence to be of uncertain provenance and currently it is not accepted onto the official British List.

The orange-bellied parrot is a small parrot endemic to southern Australia, and one of only three species of parrot that migrate. It was described by John Latham in 1790. A small parrot around 20 cm (8 in) long, it exhibits sexual dimorphism. The adult male is distinguished by its bright grass-green upper parts, yellow underparts and orange belly patch. The adult female and juvenile are duller green in colour. All birds have a prominent two-toned blue frontal band and blue outer wing feathers.

<span class="mw-page-title-main">Blue-billed duck</span> Species of bird

The blue-billed duck is a small Australian stiff-tailed duck, with both the male and female growing to a length of 40 cm (16 in). The male has a slate-blue bill which changes to bright-blue during the breeding season, hence the duck's common name. The male has deep chestnut plumage during breeding season, reverting to a dark grey. The female retains black plumage with brown tips all year round. The duck is endemic to Australia's temperate regions, inhabiting natural inland wetlands and also artificial wetlands, such as sewage ponds, in large numbers. It can be difficult to observe due to its cryptic nature during its breeding season through autumn and winter. The male duck exhibits a complex mating ritual. The blue-billed duck is omnivorous, with a preference for small aquatic invertebrates. BirdLife International has classified this species as Least concern. Major threats include drainage of deep permanent wetlands, or their degradation as a result of introduced fish, peripheral cattle grazing, salinization, and lowering of ground water.

The Point Cook Coastal Park covers an area of 863 hectares and includes the Cheetham Wetlands. The park extends from the RAAF Williams Point Cook Base northeast along the coast to the Laverton creek which comprises its northern boundary. The park is approximately 20 kilometres (12 mi) from Melbourne, Australia in a southwesterly direction along Port Phillip Bay. The park is adjoined by the Point Cook Marine Sanctuary, which extends around the point to the south and the east. The northwestern boundary to the park is residential housing.
