Immature birds of the herons breeding on Palawan are buff heavily overlaid with black. 2000), uncommon in both seasons in China (mainland, Taiwan – Sykes 1996), breeds throughout the Philippines but is uncommon in both seasons, rare in nonbreeding season in Java (McKinnon 1993). In Birds of the World (J. del Hoyo, A. Elliott, J. Sargatal, D. A. Christie, and E. de Juana, Editors). The Malayan night heron has been found in India, Sri Lanka, Brunei, Nepal, Bangladesh, Myanmar, Cambodia, Laos, Vietnam, Thailand, Malaysia, Singapore, China, Indonesia, the Philippines, Taiwan and Japan. [4] It also produces hoarse croaks and arh, arh, arh. Juvenile: The immature is cryptically colored, strikingly different from the adult. I studied the reproductive success of the Malayan night heron in the urbanized areas of Tai-chung, Nan-tao, Yun-lin, and Chia-I Counties, in Central Taiwan. Both birds of a pair build nests. Herons from the Nicobar Islands are small. Adult: The crown and nape are black, ending in a long black crest. It is distributed in southern and eastern Asia. 1997), the Philippines (to Palawan), and Japan (Ryukyu Islands). It nests in trees and also in reed beds. Variation: The sexes are alike, but the male may have a longer crest and bluer lores in courtship (Tsao 1998). The bill is stocky, down-curved, dark brown above and green below. It has been proposed that the species might be an indicator of environmental quality in wet tropical and subtropical forests, but this needs to be demonstrated (Perennou et al. [1] This bird occurs in forests, streams, and marshes. The flight feathers are brownish-black with white tips, visible in flight. The tail is black. Trans. It is distinguished from the Cinnamon Bittern by its short stubby (not long and pointed) bill, black crown, blue green lores, larger size, barred cinnamon back (not plain cinnamon or brown with buff spots), black and cinnamon wings with white flight feather tips (not uniformly cinnamon). [4] The crown is black, the chin is white, and the eyes are yellow. It is nocturnal and is found in forests. The lores and orbital skin are blue green. The Malayan night heron (Gorsachius melanolophus), also known as Malaysian night heron and tiger bittern, is a medium-sized heron. The Malayan Night Heron stands about 47cm tall. The bill is stocky, down-curved, dark brown above and green below. Ardea melanolopha Raffles, 1822. It is a colonial nester, with 20 nests close together. Recent information reporting immature birds in Malaysia (Peninsular, Taman Negra), Java, and Borneo suggests nesting, but this needs to be confirmed (Perennou et al. Cornell Lab of Ornithology, Ithaca, NY, USA. Breeding birds have an especially bright blue facial skin patch between the bill and the eyes; the patch is faded in non-breeders, and yellowish in juveniles. 2000). No quantitative information is available on nesting success. During the day, it roosts well hidden in reed, bamboo, and other dense vegetation. No doubt its habitat, like that of other Gorsachius herons, has been reduced due to deforestation and degradation. 2000, R. Lansdown pers. 2000). The crown is blackish barred and spotted with white. 2000), Sri Lanka, Thailand, Laos, Cambodia, Vietnam, south China (Hainan, Guangzhou, Taiwan), Malaysia (Malay Peninsula, Sarawak), Indonesia (Sumatra, Java, Kalimatan, Halmahara, Talaud) (Coates et al. Malayan Night-Heron (Gorsachius melanolophus), version 1.0. Under parts are white, spotted and barred brown. It occasionally nests in reed beds. It nests in May–August during the big rains in west India, May–June in Assam, April–September in Taiwan. The Malaysian Night-Heron is distinguished from the Japanese Night-Heron by its chestnut brown (not darker body color), Black (not tawny) crown and longer crest, slightly longer thinner bill, and white (not tawny) tips on primaries. ), the Philippines (including Palawan), and Japan (Ryukyu Islands). Intensive year-round surveys need to be conducted in suitable habitat in order to determine its status in various places. Its neck and breast are rufous. The immature Malayan Night-Heron is distinguished from the immature Rufous and Black Crowned Night-Herons by its short, stubby and downward-arched bill, smaller size, finer spotting on the back and wings, and mottled (not stripped) under parts. https://doi.org/10.2173/bow.manher1.01 Status: No data are available on population sizes. But the habitat needs of the species are not well understood, given that it is often reported to be using human-made habitats, and on Taiwan it nests in parks and near human residences (Chang 2000). It defends itself with Forward consisting of raised crest, open wings, and stabbing at the opponent. [7] A study of its pellets found reptiles, snails, chilopods, arachnids, crabs and insects. Birds have been seen outside the usual range, but not very far, (Shikoku Island), Palau Island, Indonesian islands (Bandai) and Christmas Island. Other names: Malay Tiger Bittern in English; Martinete Malayo in Spanish; Bihoreau malais in French; Wellenreiher in German; Zuguro-mizo-goi in Japanese; Bakaw-gabi in Pilipino (Philippines); Kowak melayu in Indonesian; Helguan yan in Chinese. It is distributed in southern and eastern Asia. It also nests solitarily. It is solitary forager that feeds by Walking slowly at the edges of water, fields and other feeding areas. The species shows a high degree of individual variability in plumage. Nonbreeding range: It occurs during non-breeding in west India (Perennou et al. The Malayan Night-Heron is nocturnal, although it feeds readily crepuscularly and by day as well. Flanks and undertail-coverts mottled brown and white. Adults have black crowns, and are reddish-brown overall, with dark reddish-brown underparts with fine streaks, and black underwings. The Malayan Night-Heron is a small chestnut and brown nocturnal heron of low to mid elevation wet forests. So little is known of this heron that much of its basic biology is speculative and it is not certain what constitutes the essential characteristics of a nocturnal low- to mid-elevation wet forest heron.
