Summary

by William Swainson Zoological Illustrations — Vol I. Pl… (1820)

Tail the same colour, the exterior basal margins olive: all the feathers are narrow, pointed, and gradually lengthening, the middle pair being two inches three quarters longer than the outer pair, which exceed those next them by an inch. The feet are very pale yellow, and three-quarters of an inch from the knee to the claws, the three foremost of which are equally connected together (though slightly) nearly as far as the first joint; the outer and inner toes equal, and rather shorter than the hind-toe: claws slender and much compressed.
