The bird-watchers spotted a long-whiskered owlet, a species first discovered in 1976 that has remained largely out of sight since.
The tiny species, Xenoglaux loweryi, has long bristles around its beak, and delicate feathers that extend into whiskers.
Its formal Latin name actually means "strange owl".
The long-whiskered owlet is listed as Endangered by the International Union for the Conservation of Nature, because of its very limited range of approximately 73 square miles.
The bird's habitat is restricted to cloud forests - moist, tropical forests characterised by frequent low cloud cover.
