Siamese fireback

A large pheasant and national bird of Thailand.

Last updated

The Siamese fireback (Lophura diardi), also called Diard's fireback, is a sizable pheasant reaching about 80 cm in length. Males display grey plumage, a large red facial caruncle, crimson legs and feet, ornamental black crest feathers, reddish brown eyes, and a long, curved, blackish tail. Females are brown with blackish wings and tail feathers.

This bird inhabits lowland and evergreen forests across Cambodia, Laos, Thailand, and Vietnam in Southeast Asia. In June 2025, a wild individual was observed in the forested area of Ranikhet, a popular tourist spot in Uttarakhand, India. The Siamese fireback is Thailand's national bird. Females typically lay four to eight rosy eggs.

Its scientific name honors French naturalist Pierre-Médard Diard. In Thai, it is known as Kai Fah Phaya Lo (Lord Lo's pheasant), a name drawn from the folk tale Lilit Phra Lo, in which the hero Phra Lo follows the pheasant and meets his lovers, sisters Phra Phuean and Phra Phaeng. Once assessed as Near Threatened on the IUCN Red List due to habitat loss and over-hunting, the species is now listed as Least Concern.

Lore & Background

The Siamese fireback is distributed in the lowland and evergreen forests of Cambodia, Laos, Thailand, and Vietnam in Southeast Asia. The male has grey plumage with an extensive facial caruncle, crimson legs and feet, ornamental black crest feathers, reddish brown iris, and a long curved blackish tail. The female is a brown bird with blackish wings and tail feathers. The female usually lays between four and eight rosy eggs.

The scientific name commemorates the French naturalist Pierre-Médard Diard. In Thai, the species has a common name Kai Fah Phaya Lo (Lord Lo's pheasant), according to Thai folk literature, Lilit Phra Lo, where the protagonist Phra Lo is charmed by following the pheasant until he meets Phra Phuean and Phra Phaeng, the two sisters and later his lovers.

Due to habitat loss and over-hunting in some areas, the Siamese fireback was evaluated as Near Threatened on the IUCN Red List; however, it is now Least Concern.

Reader's Guide

The Siamese fireback holds significance as Thailand's national bird, reflecting its cultural importance within the region. Its common name in Thai, Kai Fah Phaya Lo, ties directly to the folk literature Lilit Phra Lo, where the pheasant serves as a narrative device leading the protagonist to his lovers. This literary connection embeds the bird in Thai cultural heritage. The species was also spotted naturally in the forest area of Ranikhet, a popular tourist destination in Uttarakhand, India, in June 2025, extending its known range beyond Southeast Asia.

Its conservation status has shifted from Near Threatened to Least Concern, indicating that while habitat loss and over-hunting remain threats in some areas, the overall population is no longer considered at immediate risk. The bird's scientific name honors French naturalist Pierre-Médard Diard, linking it to the history of natural science. The Siamese fireback's distinctive appearance—the male's grey plumage, facial caruncle, crimson legs, and ornamental crest—makes it a notable species among pheasants. Its presence in lowland and evergreen forests across four Southeast Asian countries underscores its ecological role in those habitats.
