It feeds by diving for insects, polychaete worms, crustaceans, and salamanders. The "Clark" of its common name—and its specific epithet clarkii—honors John Henry Clark, a 19th-century American surveyor who was also a naturalist and collector. Description: Identification of Clark’s Grebe is possible in the field. Let us send you the latest in bird and conservation news. Partners In Flight estimates an overall 8% population decline between 1970 and 2017, and a global breeding population of just 11,000 individuals.

Photo: Dick Dickinson/Audubon Photography Awards, Adults and downy young. Range and Habitat Clark's Grebe: Breeds from British Columbia, Saskatchewan, and Minnesota south to southern California, and sparsely to Arizona, New Mexico, and Colorado. Aechmophorus clarkii clarkii (n and c Mexico); Aechmophorus clarkii transitionalis (w Canada and w USA) Concurrently, the winter climate space for this species in … Clark's grebes appear to have semi-monogamous behavior, staying with a single mate, but possibly only for a single season as far as known. That he was able to study the birds at all at that time was remarkable. State Status: Candidate, 2001 (Western) and 2010 (Clark’s) Federal Status: None Recovery Plans: None. Some researchers suggest "grebe" is possibly derived from the French griabe meaning "sea mew". The origin of the name "Grebe" is uncertain. [13], In 1858 the lighter-coloured morph had first been described as a separate Mexican and Californian species, Podiceps clarkii by George N. Lawrence. Ratti, John T. (1977). Clark's … CLGR. Now an Audubon chapter is fighting back to ensure that birds and locals get all the hydration they need. Some birds appear to be intermediate and should be left unidentified. Fall migrants away from the breeding range are most conspicuous, though rare, in Sep-early Oct. As with Western Grebe, lingering birds are found each fall at Lake McConaughy; there are about 16 records there (including two for CBC Count Week) 10 Nov-2 Jan 1997-2017 (Brogie 1998). We saw these marvelous waterbirds at the Tulelake National Wildlife Refuge in Northern California near Klamath Falls. Clark’s Grebes are migratory in much of their range and will winter off of the Pacific Coast. Bill is yellow-orange. Studies in the 1970s and 1980s showed that Western and Clark's, though extremely similar, are actually two distinct species. Clark’s Grebe, but only A. c. transitionalis is found in Wyoming and surrounding states 2, 7. Clark's Grebe. [10], Dickerman in 1963 was the first to cast doubt on the taxonomic status of the taxon, believing that the synonymy was incorrect, and thus he moved Lawrence's Podiceps clarkii to Aechmophorus clarkii, and restricted the distribution of this taxon to Mexico, rejecting Lawrence's identification of the larger-sized, pale-colored birds from California and elsewhere in the US and Canada as this taxon. As the two distinct species occupy the same range and habitat, it becomes a challenge for the beginning birder to differentiate the two. Prior to 1985 the Clark's Grebe was considered the same species as the Western Grebe.. Western and Clark’s grebes are closely related picivorous aquatic birds that once were considered different color phases of the same species (Figure 1), and they do occasionally interbreed (Konter 2011). Discover Life's page about the biology, natural history, ecology, identification and distribution of Aechmophorus clarkii - Clarks Grebe -- Discover Life The Least Grebe is the smallest in the family and lives in the most southerly regions of the United States and into Mexico.

Deignan designated this last specimen as the holotype in 1961. Audubon’s climate model projects that the Clark’s Grebe is in serious trouble, its summer range nearly completely shifting and slightly shrinking by 2080, a radical change that this species may have trouble following. The Clark’s Grebe, like other grebes, spends almost all its time in water and is very awkward when on land. Our email newsletter shares the latest programs and initiatives. As a family, grebes are known for their elaborate courtship displays. [3], It performs the same elaborate courtship display as the western grebe.[4]. Range: Both birds share the same range and habitats in western North America, but Clark's grebes are much rarer and have a smaller range spread, particularly to the north and east. ...

Audubon protects birds and the places they need, today and tomorrow. In one study on lakes in Oregon, Clark's tended to feed farther from shore and in deeper water. [15] These courtships take place during spring migration and shortly after arriving on the breeding grounds. See more ideas about bird photography, bird, clarks. We calculated stride duration using high-speed video recordings from 40 occurrences of grebe rushing. Clark's Grebe: Large grebe, gray-black upperparts, white underparts, and slender neck with white on front and black on back. Length range: 21.6-29.5 in (55-75 cm) Weight: 25.3-59.4 oz (718-1685 g) Wingspan range: 31.9-32.3 in (81-82 cm) Clark’s Grebe Behavior In 1985 the American Ornithologists’ Union (1998) decided these two were separate, based on DNA-DNA hybridization data, bill color, facial plumage, vocalization and … This species nests on large inland lakes in western North America and migrates to the Pacific coast over the winter. However, most can be separated. The extensive black on the culmen seems beyond the range of Clark's Grebe, but photos show rather typical Clark's with an equal amount of dark on culmen. Bald Eagle. [2], Storer and Nuechterlein in 1992 dubiously claim the birds winter in Central America, as well as in Mexico and some regions of California. Clark's Grebe (Aechmophorus clarkii) is a North American species in the grebe family. Its breeding range in Oregon overlaps that of western grebe, but Clark's is not as common. However, during the winter, the facial patterns of these two species are nearly identical, making identification much more challenging. [10][11], According to Robert W. Storer in 1965 besides the paler coloration there were other more subtle morphological differences between the two taxa: the bill of the western grebe is greenish-yellow, whereas this grebe has a bright yellow bill, and furthermore the black color of the crown extends less far down for this grebe, with the black extending below the eye, the lores and the thin line of bare skin extending from the eye to the corner of the bill in the case of the western grebe, whereas in this grebe the black reaches somewhat less far, leaving a thin line of paler color above the eye. Clark’s Grebes are migratory in much of their range and will winter off of the Pacific Coast. Breeding range extends through southern Canada, the Dakotas, Montana, and Idaho into eastern Oregon, and south into Nevada andf California. Department of Fish and Game lists the Clark’s Grebe Figure 2. Choose a temperature scenario below to see which threats will affect this species as warming increases.

Clark’s Grebes are migratory in much of their range and will winter off of the Pacific Coast. The Western Grebe is basically identical to the Clark's Grebe in terms of size, shape, behavior and natural range. [10][11], After the presence of this taxon throughout the range of the western grebe was discovered, along with the identical behaviour, the two taxa were synonymised, and this was situation was accepted by ornithologists throughout the first half of the 20th century. Aechmophorus clarkii It was long thought the Clark’s Grebe was a pale morph of the Western Grebe, which it resembles in size, range, and behavior. Clark's Grebe (Aechmophorus clarkii) is a large (55-75 cm) waterbird that has a black cap and back, white neck and underside, and is distinguishable from the western grebe (Aechmophorus occidentalis) by their white face and bright yellow bill. Like the western grebe, Clark's grebe is a specialist in fish, which make up over 80 percent of its diet. ephemeralis. Large, long-necked grebe.

It is important to note that while there are very few cases of breeding between clark's and western grebes, there have been cases where phenotypic hybrids (birds with plumage that is similar to both species) have mated and produced fertile offspring. It is believed, however, that this becomes less likely when the individuals are from different migrations and are not hybrids, as they have a greater chance of failing during the courtships. Intermediates occur, and hybrids or individual variation arguably make some birds impossible to id. Western and Clark’s grebes were once considered color morphs of a single species. It is a large aquatic diving bird; adults weight between 800–1,800 g, range in length from 55–75 cm, and have a wingspan of approximately 61 3, 8cm . The Western Grebe and the Clark’s Grebe look identical at first glance. Bird Description Same as WEGR for most features, but about 10 times scarcer. See more ideas about clarks, bird photography, birds. The extensive black on the culmen seems beyond the range of Clark's Grebe, but photos show rather typical Clark's with an equal amount of dark on culmen. They are medium-sized birds that almost resemble the crown in size. Lighter-colored morphs in Mexico are said to have orange-coloured bills, and the darker morphs have yellow bills. Until the 1980s, it was thought to be a pale morph of the western grebe, which it resembles in size, range, and behavior. All logos, trademarks and … [7] A common name advocated in Spain for this bird is the calque achichilique de Clark. [9], There are few changes between the sexes, the most notable feature that distinguishes males from females is the presence of a slight crest on the heads of males. ephemeralis for the larger, migratory, lighter-colored grebes of the US and Canada, and A. clarkii ssp. Zoom in to see how this species’s current range will shift, expand, and contract under increased global temperatures. It will also eat other aquatic organisms like crayfish, amphibians, and aquatic insects. Although Clark's may be found with Western Grebes at all seasons, it tends to associate more with its own kind. [2] Out of almost 100,000 records of this taxon logged at the Global Biodiversity Information Facility there are zero records found south of northern Oaxaca, Mexico. As there are fewer females than males, the final decision of whether or not mating occurs depends on the females. As the two distinct species occupy the same range and habitat, it becomes a challenge for the beginning birder to differentiate the two. Stride duration and frequency. Cute Birdorable Clark's Grebe, also known as Mexican Grebe, in Loons & Grebes. Often found together. Also note single reedy creeeee call (unlike Western's doubled call). Illustration © David Allen Sibley. Intermediates occur, and hybrids or individual variation arguably make some birds impossible to id. The neck structure of the Clark's Grebe allows it to thrust its beak forward, like a spear, which it does to catch prey.

They entail a sequence of performances and advertisements/dances with the partner, or presenting the partner with a bundle of weeds and performing a different set of dances, respectively. Bill is yellow-orange. transitionalis for the smaller often non-migratory, darker-colored grebes of Mexico. Text © Kenn Kaufman, adapted from Stride duration and frequency. Its breeding range in Oregon overlaps that of western grebe, but Clark's is not as common. The two taxa can even successfully cross-breed, with intermediates as a result. It also found that although the birds inhabited the same wetlands and the same habitats, the populations were not randomly distributed, with the taxa preferentially nesting with their own morph, and colonies being in large part of one type or the other, despite that one morph was much rarer in frequency than the other. It is closely related to the Western Grebe; until the 1980s the two were considered to be the same species. Clark’s Grebes are migratory in much of their range and will winter off of the Pacific Coast. [2] Until the 1980s, it was thought to be a pale morph of the western grebe, which it resembles in size, range, and behavior. [11], By 1992 Storer and Gary L. Nuechterlein, both having studied the grebes in the 1970s, recognised the paler-coloured morphs in the US and Canada in the book 'The Birds of North America' as A. clarkii, thus apparently rejecting Dickerman's species concept and subspecific classification, although they do not explicitly state this, and because this work does not include Mexico as part of North America, his work is not actually in their remit. Of the three specimens Lawrence used, two were larger, migratory birds from California, whereas a single specimen was a smaller bird from Laguna Santa Maria in Chihuahua. The neck structure of the Clark's Grebe allows it to thrust its beak forward, like a spear, which it does to catch prey. Clark's Grebe: Large grebe, gray-black upperparts, white underparts, and slender neck with white on front and black on back. Storer and Nuechterlein in 1992 claim that the bill is slightly upturned in this species whereas the western grebe has a straight bill, this was not noted in earlier studies. Described to science in 1858, Clark's Grebe was soon dismissed as a mere variant of Western Grebe, and thereafter was ignored for over a century. Direct flight on rapid wing beats. Lives of North American Birds. Studies during the 1980s led science to recognise these as separate species. The North American and Eurasian species are all, of necessity, migratory over much or all of their ranges, and those species that winter at sea are also seen regularly in flight. [2], Its relative size compared to the western grebe is confused. Looking carefully at their black crests, the Western’s extend into or even below the eyeline, while the Clark’s … Read more [2][10][11], Although darker and lighter-colored morphs of grebes occur in the resident non-migratory populations occur in Mexico, it is unclear if these can be distinguished by the other morphological characteristics described above, as most studies have only looked at US populations.

Grebe, (order Podicipediformes), any member of an order of foot-propelled diving birds containing a single family, Podicipedidae, with about 20 species.They are best known for the striking courtship displays of some species and for the silky plumage of the underparts, which formerly was much used in millinery. In areas where both are common, they frequently form Breeding range extends through southern Canada, the Dakotas, Montana, and Idaho into eastern Oregon, and south into Nevada andf California. In the winter in California numerous examples of dark-colored western grebes displayed the mostly white face of Clark's grebe, although this was intermediate and thought to be possibly due to seasonal changes. Clark’s Grebe Size . Rushing displays typically last 4 s, but range up to 7 s (Nuechterlein and Storer, 1982).The data capacity for the high-speed cameras limited each trial to 1.7 s at 325 f.p.s. Until the 1980's thought to be a pale morph of the Western Grebe. Described to science in 1858, Clark's Grebe was soon dismissed as a mere variant of Western Grebe, and thereafter was ignored for over a century. Aechmophorus clarkii.
