How does the tooth-billed bowerbird see?

The tooth-billed bowerbird (Scenopoeetes dentirostris) is a bird in the order Passeriformes. Its eyes belong to the vision type UV songbird, parrot and hummingbird.

Measured in this species: colour and night vision. Measured colour or sharpness: a measured receptor set or acuity in this species; other dials come from relatives or group defaults. Every value below carries its evidence level and sources; nothing is typed by hand.
