The male crested partridge is metallic green and dark blue with a tall red crest; the female is pea-green with a grey head and lacks the crest. Both have red bare skin around the eye and red legs. Pairs probe rainforest leaf litter for fruit, seeds and invertebrates, usually running rather than flying when disturbed. Both parents feed the chicks bill-to-bill (Wikipedia, general species account). It is Nationally Critically Endangered (Thailand Red Data 2025).
