Giant coot 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. Giant coot The giant coot ("Fulica gigantea") is a species of coot from South America. It is found at lakes in the altiplano from central Peru, through western Bolivia, to north-eastern Chile and extreme north-western Argentina. With a total length of 48–64 cm (19–25 in), it is the second largest extant member of the
American coot weights and laying sequence, wherein earlier eggs are larger than eggs laid later in the sequence. It is possible to induce a female coot to lay more eggs than normal by either removing all or part of her clutch. Sometimes, a female may abandon the clutch if enough eggs are removed. Coots, however, do not respond to experimental addition of eggs by laying fewer eggs. The American coot is a persistent re-nester, and will replace lost clutches with new ones within two days of clutch-loss during deposition. One study showed that 68% of destroyed clutches are eventually replaced. Re-nested clutches
