Frill-necked monarch is a small bird from the monarch family. Males have a large collar of white feathers on the neck, which they spread during mating displays or when in danger.
Frill-necked monarch differs from related species by the bright white collar in males, which is used in mating rituals. The bird is important for the forest because it regulates insect populations.
