Description

With a total length of 48–64 cm (19–25 in),[2] it is the second largest extant member of the family Rallidae, after the takahe from New Zealand, and adults are considered functionally flightless.[3] It is the only coot with reddish legs.[2] It has a small white frontal shield. Its beak is tipped black. An adult male weighed 2.7 kg (6.0 lb) while three adult females weighed 2.03–2.4 kg (4.5–5.3 lb).[4]

Breeding

As in the related horned coot, the giant coot is monogamous and the pair builds a huge nest in a highland lake. However, unlike the horned coot, the nest of the giant coot is primarily made of aquatic vegetation and – as it is fiercely territorial – it never forms colonies.[3]
