Life Cycle
The male pied-billed grebe or a male and female pair establish a territory during breeding season. Both the male and female gather vegetation from the pond or marsh bottom and build a floating nest in shallow water. The female pied-billed grebe lays 2-10 eggs. Both the male and female incubate the eggs. Incubation takes about 23-27 days.
The chicks are precocial and leave the nest within an hour of hatching. Although they can swim and dive as soon as they leave the nest, the parents protect the chicks and sometimes carry them on their backs. The chicks leave their parents when they are one to two months old. In the southern parts of their range, females may have two broods a year.
Behavior
The pied-billed grebe is an excellent swimmer and diver. It often dives to evade predators. In fact, another name for the pied-billed grebe is the Hell-diver.
