How does the lesser flamingo see?

The lesser flamingo (Phoeniconaias minor) is a bird in the order Phoenicopteriformes. Its eyes belong to the vision type Panoramic grain-eater and wader.

Measured in this species: field of view and night vision. One measured dial: a value other than colour or sharpness is measured in this species; colour and sharpness are not measured here. Every value below carries its evidence level and sources; nothing is typed by hand.

What stands out

The six dials

Evidence levels: how the tiers work. "Measured" means a value measured in this species; "Estimated" values come from a close relative or an eye-size formula.
