The Great Crested Grebe is a largest member
of the grebe family, “Podicipedidae” found in China . It is about twice the size
of the smallest Chinese grebe, the Little Grebe. It is a handsome waterbird named for the
prominent tufts of feathers on the head.
This bird is widespread through
The Great Crested Grebe can be found in
freshwater lakes during the summer breeding season and in freshwater and
saltwater environments, especially along the seasides of eastern China
in winter.
Like other grebes, this species feeds
primarily on fish, but it will also eat crustaceans, insects and frogs. It is
capable of deep dives underwater to pursue fish and other aquatic creatures.
All grebes are supremely adapted for life
in the water which makes them ill equipped to move on land. For example, a
grebe’s leg is set far back near the rump. This adaptation aids in swimming,
but makes walking on land a near impossibility. All grebes nest directly beside
water to avoid the necessity of land movement.
Several grebe species have elaborate
courtship displays, and the Great Crested Grebe is no exception. In the
freshwater lakes of their summer breeding grounds, these birds put on a dance
performance of great artistry. A pair of birds face each other and lift their
bodies out of the water while nodding their heads up and down, often while
holding vegetation in their bills.
A typical brood consists of two eggs. When
the chicks hatch, each parent will identify a favorite chick and take sole
responsibility for the raising that chick.
