The white-eared night heron (Oroanassa magnifica) is a species of

habitat loss and habitat fragmentation.[4]

Taxonomy

The white-eared night heron was collected in

monotypic.[6]

Distribution and habitat

This heron is found in southern China and northern Vietnam. Its range size is estimated at 2,180,000 km2 (840,000 sq mi).[1] By 2001, the species had only been recorded from about 20 localities; in the ten years from 2001 to 2011, surveys discovered it in more than 30 localities, making its known range much larger.[4][7] Its natural habitat is subtropical or tropical forests and rivers. It has also been found in human-modified habitats.[4]

Description

The length is 54–56 cm (21–22 in).[4] The male is mostly blackish-brown. The neck-sides are chestnut.[6] The lores are yellow, and the beak is black. The eyes are yellow-orange.[6] The head and nape are blackish. The postocular stripes and throat are white. The underparts are brown, with white streaks.[4] The tarsi are green.[6] The female is similar to the male, but its head and neck are less distinctly patterned. The female also has whitish streaks on its back and wings.[4] The juvenile is similar to the female, but has a browner plumage and buff spots.[4]

Behaviour and ecology

Like other

fledging has been observed in late April. Breeding seems to occur earlier in Vietnam than in China.[9] The nest is in the shape of a circular tray. A study found that fledging occurred more than two months after hatching, longer than most other species of heron.[10]

Status and conservation

The

Ba Be National Park.[4]
