Baillon's crake (Porzana pusilla) or the marsh crake, is a small waterbird of the family Rallidae.

Contents

Distribution

Their breeding habitat is sedge beds in Europe, mainly in the east, and across Asia. They used to breed in Great Britain up to the mid-19th century, but the western European population declined through drainage. There has been a recovery in north-western Europe in recent years, with the recolonisation of Germany and the Netherlands, and breeding suspected in Britain; an Irish record in 2012 was the first there since the 1850s. [2] They nest in a dry location in wet sedge bogs, laying 4–8 eggs. This species is migratory, wintering in east Africa and south Asia.

It is also a resident breeder in Africa and Australasia. There is a single North American record of this species on Attu Island in September 2000.

Description

They are 16–18 cm (6.3–7.1 in) in length, and are similar to the only slightly larger little crake. Baillon's crake has a short straight bill, yellow or green without a red base. Adults have mainly brown upperparts with some white markings, and a blue-grey face and underparts. The rear flanks are barred black and white. They have green legs with long toes, and a short tail which is barred underneath.

Immature Baillon's crakes are similar to the adults, but have extensively barred underparts. The downy chicks are black, as with all rails.

Behaviour

These birds probe with their bill in mud or shallow water, also picking up food by sight. They mainly eat insects and aquatic animals.

Baillon's crakes are very secretive in the breeding season, and are then mostly heard rather than seen. They are then noisy birds, with a rattling call like that of the edible frog, or perhaps garganey. They can be easier to see on migration or when wintering.

Taxonomy and nomenclature

This bird is named after French naturalist Louis Antoine Francois Baillon. The names marsh crake and tiny crake have previously been used to refer to this species. The genus name Porzana is derived from Venetian terms for small rails, and pusillus is Latin for "very small". [3]

Status

International

The Baillon's crake is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) applies.

Australia

Baillon's crakes are not listed as threatened on the Australian Environment Protection and Biodiversity Conservation Act 1999. However, their conservation status varies from state to state within Australia. For example:

Great knot species of bird

The great knot is a small wader. It is the largest of the calidrid species. The genus name is from Ancient Greek kalidris or skalidris, a term used by Aristotle for some grey-coloured waterside birds. The specific tenuirostris is from Latin tenuis "slender" and rostrum "bill".

Magpie goose Species of bird

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 the local aboriginals 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 protective management".

Blue-billed duck 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 Near Threatened. 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 African crake is a small to medium-size ground-living bird in the rail family, found in most of central to southern Africa. It is seasonally common in most of its range other than the rainforests and areas that have low annual rainfall. This crake is a partial migrant, moving away from the equator as soon as the rains provide sufficient grass cover to allow it to breed elsewhere. There have been a few records of vagrant birds reaching Atlantic islands. This species nests in a wide variety of grassland types, and agricultural land with tall crops may also be used.
