Avian Feet

[Klipspringer]

Most plovers and lapwings have a vestigial back toe high up on the foot.

Bustards and korhaans lack the back toe and are proper ground birds.

A sandgrouse has a tiny minute back toe, you can not see it.

My bustards and korhaans have their feet in the grass. At least the ones that I have found up to now

At least it shows that the Kori bustard does not have a toe behind

[Klipspringer]

Yep. They do well with three toes must be good for running

[ExFmem]

Three toes (?) and also Semipalmate (small web between the toes)

Black-necked Stilt?

[ExFmem]

Yes, Black-necked Stilt.
