Orden: Gruiformes - Familia: Rallidae
The Red-gartered Coot is a resident bird which breeds at Costanera. Two other coot species coexist in the pond: the White-winged and the Red-fronted Coots. It is stubby and its wings are not well adapted to fly.
Both male and female cooperate in nest building. They use vegetal material which they pile up and arrange on a solid base. They look for material anywhere and it is common to watch them return from far with twigs in their bill. They are very dilligent. Both may be away on the search or one of them arranges what the other one brings.
The nest is surrounded by water and anchored to a clump of reeds.
