The eared grebe (Podiceps nigricollis), also commonly known as the black-necked grebe, is the most common species of the grebe family of water birds. They belong to the order Podicipediformes, family Podicipedidae, and class Aves. These birds are found throughout a large range that occurs in freshwater lakes. They move to their breeding colonies in the spring season and from there, molting migration occurs in the summer. Most of the birds molt at the end of the molt migration so that dark feathers appear before reaching their colonies. They winter either in parts of Asia and Africa or in America. In North America, these birds mostly populate the Great Salt Lake in Utah and the Mono Lake in California. Eared grebes do not have many dissimilarities in appearance between the two genders. Until now, there are a large number of eared grebes that are found throughout their range however, they are gradually decreasing in number.

The courtship will only occur  when the finally reach the breeding nests. A male bird follows an elaborate courtship display.  They puff their bodies and stroke their wings in such a way that their golden plumes are properly visible to attract females.

Eared Grebe Fun Facts

What do eared grebes look like?

An eared grebe (Podiceps nigricollis) is a small waterbird with a small head and dark thin neck. The bill is also extremely thin and dark. In the breeding plumage, their feathers turn dark black or brown in the head, neck, and underparts. Golden plumes can also be spotted on both sides of its head during its breeding plumage. They have a dark red eye with yellow detailing. In the non-breeding plumage, the feather colors fade. Young birds resemble an adult's non-breeding plumage with a paler neck and throat. The thin bill of the bird differentiates it from other grebe species like horned grebes. The color of the bill turns darker during the breeding plumage.

An eared grebe spends most of its life in water.

When they reach the saline lakes during molting, they feed on brine shrimp. Juveniles are fed one at a time and they grab the food from the parent's beak. Like eared grebes, young grebes are also carnivores who feed on amphibians, mollusks, fish insects, and shrimps, prawns, and other crustaceans.

Did you know...

Eared grebes become flightless for around nine to 10 months in a year due to molting. They are clumsy on land because their legs are behind their bodies which makes it hard for eared grebes to fly. However, they are much better in the water than in the air and are able to run on water.

Do grebes dive?

All birds in the grebe species nest in lakes and ponds and dive underwater in search of food. They also dive underwater to hide from predators.
