Grebes nest on floating platforms made up of waterweed. Grebes (/ˈɡriːbz/) are aquatic diving birds in the order Podicipediformes /ˌpɒdɪsɪˈpɛdɪfɔːrmiːz/. While there are a few prehistoric genera that are now completely extinct; Thiornis (Late Miocene -? [1] Grebes are widely distributed birds of freshwater, with some species also occurring in marine habitats during migration and winter. indet. The genus name is from Ancient Greek takhus "fast" and bapto "to sink under". At 23 to 29 cm in length it is the smallest European member of its family. This is when birds fly to live in a different place in summer or winter. Breeds in colonies. Outside the breeding season, it can be confused with the non-breeding Australasian Grebe, but it can be distinguished by its dark crown that extends below the eye. They swim by simultaneously spreading out the feet and bring them inward with the webbing expanded to produce the forward thrust in much the same way as frogs. Western Grebe: Large, long-necked grebe with dark gray upperparts, white underparts, gray sides and flanks. The order contains a single family, the Podicipedidae, which includes 22 species in six extant genera.

Grebes make floating nests of plant material concealed among reeds on the surface of the water. Illustration © David Allen Sibley. The specific ruficollis is from Latin rufus "red" and Modern Latin -collis, "-necked", itself derived from Latin collum "neck". [31] and subspecies names from English Names of Birds. This is when birds fly to live in a different place in summer or winter. Young: Climb onto back of parent within minutes after hatching, soon leave nest; are fed by both parents. [28], Living Podicipediformes based on the work by John Boyd. Some species of grebe will go to saltwater (sea/ocean) when they are migrating.

Accordingly, they were at first believed to be related to the loons, which are also foot-propelled diving birds, and both families were once classified together under the order Colymbiformes. Text © Kenn Kaufman, adapted from Wings have white stripes visible in flight. Although they can run for a short distance, they are prone to falling over, since they have their feet placed far back on the body. Nest (built by both sexes) a floating heap of plant material, anchored to standing vegetation. [6] In retrospect, the scientific value of the debate lies more in providing examples that a cladistic methodology is not incompatible with an overall phenetical scientific doctrine, and that thus, simply because some study "uses cladistics", it does not guarantee superior results. Incubation by both sexes, about 24 days. Nest: Site is in shallow water marsh. However, as early as the 1930s, this was determined to be an example of convergent evolution by the strong selective forces encountered by unrelated birds sharing the same lifestyle at different times and in different habitat. Apparently feeds mainly on fish at all seasons and in all habitats. Mexican populations of both Western and Clark's grebes may be declining as cutting of tules on lakes removes nesting habitat. Lower face and front of neck are white; black cap extends below eye. If it is indeed related to this lineage, it must represent a most basal form, as it almost certainly predates any grebe-flamingo split. They do have a tail, but it is very short and stubby and not obvious when you look at these birds. Are the Trump Administration's Environmental Rollbacks Built to Last? Lots and Lots of Practice, Inland Lakes Keep California’s Grebes Afloat—Until Waters Get Too Low. Grebes have unusual plumage. Still – actually because of this – they do confirm that these birds form a fairly ancient evolutionary lineage (or possibly one that was subject to selective pressures down to the molecular level even), and they support the non-relatedness of loons and grebes.

Grebes are small water birds similar to ducks. Now an Audubon chapter is fighting back to ensure that birds and locals get all the hydration they need. 2-4, rarely 1-6. But it is the absence of tail and the habit of fluffing-up feathers at the rear end which provide such a blunt stern. Molecular studies such as DNA-DNA hybridization (Sibley & Ahlquist, 1990)[full citation needed] and sequence analyses fail to resolve the relationships of grebes properly due to insufficient resolution in the former and long-branch attraction in the latter. Some species of grebe will go to saltwater (sea/ocean) when they are migrating. Photo: Dick Dickinson/Audubon Photography Awards, Breeding adult and downy young. As a consequence, the discredited grebe-loon link was discussed again.
