For swimming, the grebe has lobes of skin on each toe, which offer little resistance to the water on the forward recovery, but spread wide on the backward stroke of its muscular leg. Although the grebeâ€™s foot resembles that of the coot, the latter walks on the shore well and frequently, whereas the grebe does not come out of the water even to sleep, except to crawl on the nest. its lack of walking ability is the result of his legs being set far back.
Four kinds of grebes nest in the region. The Eared Grebe, restricÂ¬ted to the western half of the U.S., is usually seen each month. But it is practically absent from the middle of June to the middle of July, and may be missed in the middle of winter.
The Pied-billed Grebe is of a different genus, and can be distinguished by its chicken bill, white patch under the tail, and dark eyes. The dark ring around the bill, which gives the bird his name, is not conspicuous in winter.
The Eared Grebe has a sharp slender bill and red eyes; in breeding plumage it has a crest and golden ear tufts. The name “grebeâ€ is derived from the Breton wordâ€™ for comb, or crest.
The Western Grebe and Clarkâ€™s Grebe are much larger birds with a heavy sharp beak like that of a heron. The only difference between the two species is how far the black on its head comes down past the eye. They nest at Balmorhea Lake in Reeves County, Texas and other larger impoundments.
