Ridgway's rail

Ridgway's rail is a species of bird found principally along the Pacific coast of North America from the San Francisco Bay Area to southern Baja California, as well as in some regions of the Gulf of California. A member of the rail family, Rallidae, it is a chicken-sized bird that lives brackish tidal marshes and rarely flies. Its name commemorates American ornithologist Robert Ridgway.

Distribution

Region

Pacific coast of North America and Gulf of California

Typical Environment

Occurs in coastal and estuarine marshes from the San Francisco Bay region south through coastal California and Baja California, with populations around the Gulf of California and lower Colorado River. It favors brackish to salt tidal marshes with dense vegetation such as cordgrass and pickleweed, intersected by tidal channels and mudflats. Inland along the lower Colorado River it uses freshwater and brackish cattail and bulrush marshes. The species is typically tied to areas with regular tidal or water-level fluctuation and abundant invertebrate prey.

Useful to know

Ridgway's rail is a secretive marsh bird of the Pacific coast, split from the clapper rail complex in 2014. It depends on extensive, healthy tidal marshes and is highly vulnerable to habitat loss and sea-level rise. Several subspecies, including the California and Yuma Ridgway's rails, have legal protection due to declining habitats.

Behaviour

Temperament

solitary and territorial

Flight Pattern

short rapid wingbeats; reluctant flier that usually stays low over marsh

Social Behavior

Typically secretive, moving through dense vegetation and along tidal creeks. Pairs form in late winter to spring and are generally monogamous within a season. Nests are cup-shaped platforms of marsh vegetation, often with canopy or ramps; both parents incubate and tend young.

Song Description

Vocalizations include a sharp series of kek-kek-kek notes and a rapid clattering ‘clapper’-like rattle. Also gives grunts and harsh scolds during territorial interactions, especially at dawn and dusk.

Rifleman

A rifleman is an infantry soldier armed with a rifled long gun. Although the rifleman role had its origin with 16th century hand cannoneers and 17th century musketeers, the term originated in the 18th century with the introduction of the rifled musket. By the mid-19th century, entire regiments of riflemen were formed and became the mainstay of all standard infantry, and rifleman became a generic term for any common infantryman.

Ring ouzel

The ring ouzel is a mainly European member of the thrush family Turdidae. It is a medium-sized thrush, 23–24 centimetres (9.1–9.4 in) in length and weighing 90–138 grams (3.2–4.9 oz). The male is predominantly black with a conspicuous white crescent across its breast. Females are browner and duller than males, and young birds may lack the pale chest markings altogether. In all but the northernmost part of its range, this is a high-altitude species, with three subspecies breeding in mountains from Ireland east to Iran. It breeds in open mountain areas with some trees or shrubs, the latter often including juniper and other treeline conifers, rowan, bilberry, heather, and hairy alpenrose. It is a migratory bird, leaving the breeding areas to winter in southern Europe, North Africa and Turkey, typically in mountains with junipers. The typical clutch is 3–6 brown-flecked pale blue or greenish-blue eggs. They are incubated almost entirely by the female, with hatching normally occurring after 13 days. The altricial, downy chicks fledge in another 14 days and are dependent on their parents for about 12 days after fledging.

Ring-billed gull

The ring-billed gull is a medium-sized gull native to North America, breeding in Canada and the northern Contiguous United States, and wintering mainly in the United States and northern Mexico. The genus name is from Latin Larus which appears to have referred to a gull or other large seabird. The specific delawarensis refers to the Delaware River.

Ring-necked dove

The ring-necked dove, also known as the Cape turtle dove or half-collared dove, is a widespread and often abundant dove species in East and southern Africa. It is a mostly sedentary bird, found in a variety of open habitats. Within range, its penetrating and rhythmic, three-syllabled crooning is a familiar sound at any time of the year. Its name is derived from the semi-collar of black feathers on the lower nape, a feature shared with a number of Streptopelia species. Like all doves, they depend on surface water. They congregate in large flocks at waterholes in dry regions to drink and bathe.

Ring-necked francolin

The ring-necked francolin is a bird species in the family Phasianidae. It is found in Burundi, Cameroon, Kenya, Rwanda, Tanzania, and Uganda. Rarer than previously believed, it was uplisted from a species of Least Concern to Near Threatened status in the 2007 IUCN Red List. This status persisted until the most recent assessment on 8th July 2024, when it was returned to Least Concern.
