Xinjiang ground jay (Podoces biddulphi) or Biddulph's ground jay, is a species of bird in the family Corvidae. It is endemic to China. It is not larger than an adult human's hand and has a brownish white coat of feathers.

Since 2004, the International Union for Conservation of Nature (IUCN) has listed the jay's conservation status as "Near Threatened" due to habitat fragmentation and degradation. [1] Its population is small, and its range is limited. [2]

Breeding

The breeding season lasts from March to May. [2] Females incubate clutches of 1-3 eggs for 18 days [2] in open [3] nests; they mainly incubate in the morning, and spend more time doing so if temperatures are low. When temperatures are high, they also shade the clutch. They prefer to nest toward the center of oases. [2]

Parents share feeding duties. [2]

Xinjiang ground jays are monogamous. They exhibit sexual dimorphism, and the males are larger than females. [2]

They are sometimes attracted to human-influenced areas such as highways, [4] but prefer not to nest near them. [5]

The yellow-billed magpie(Pica nuttalli), also known as the California magpie, is a large corvid that inhabits California's Central Valley and the adjacent chaparral foothills and mountains. Apart from its having a yellow bill and a yellow streak around the eye, it is virtually identical to the black-billed magpie (Pica hudsonia) found in much of the rest of North America. The scientific name commemorates the English naturalist Thomas Nuttall.

The ground tit, Tibetan ground-tit or Hume's ground-tit is a bird of the Tibetan plateau north of the Himalayas. The peculiar appearance confused ornithologists in the past who called it as Hume's groundpecker and still later as Hume's ground jay or Tibetan ground jay assuming that it belonged to the family Corvidae that includes the crows and jays. Although morphologically confusing, the species has since been identified using molecular sequence comparisons as being a member of the tit family (Paridae) and is the only species in the genus Pseudopodoces. It is found in the Tibetan Plateau of China, India, Nepal & Bhutan.

The piping plover is a small sand-colored, sparrow-sized shorebird that nests and feeds along coastal sand and gravel beaches in North America. The adult has yellow-orange-red legs, a black band across the forehead from eye to eye, and a black stripe running along the breast line. This chest band is usually thicker in males during the breeding season, and it is the only reliable way to tell the sexes apart. The bird is difficult to see when it is standing still, as it blends well with open, sandy beach habitats. It typically runs in short, quick spurts and then stops.

The northern mockingbird is a mockingbird commonly found in North America, of the family Mimidae. The species is also found in some parts of the Caribbean, as well as on the Hawaiian Islands. It is typically a permanent resident across much of its range, but northern mockingbirds may move farther south during inclement weather or prior to the onset of winter. The northern mockingbird has gray to brown upper feathers and a paler belly. Its tail and wings have white patches which are visible in flight.

<span class="mw-page-title-main">Black robin</span> Passerine species of bird native to the Chatham Islands

The black robin or Chatham Island robin is an endangered bird from the Chatham Islands off the east coast of New Zealand. It is closely related to the South Island robin. It was first described by Walter Buller in 1872. The binomial commemorates the New Zealand botanist Henry H. Travers (1844–1928). Unlike its mainland counterparts, its flight capacity is somewhat reduced. Evolution in the absence of mammalian predators made it vulnerable to introduced species, such as cats and rats, and it became extinct on the main island of the Chatham group before 1871, being restricted to Little Mangere Island thereafter.

<span class="mw-page-title-main">Mountain plover</span> Species of bird

The mountain plover is a medium-sized ground bird in the plover family (Charadriidae). It is misnamed, as it lives on level land. Unlike most plovers, it is usually not found near bodies of water or even on wet soil; it prefers dry habitat with short grass and bare ground. Its height is in the range of 5–9 inches, and length in the range of 8–10 inches ; and it weighs around 102 grams.

The Siberian jay is a small jay with a widespread distribution within the coniferous forests in North Eurasia. It has grey-brown plumage with a darker brown crown and a paler throat. It is rusty-red in a panel near the wing-bend, on the undertail coverts and on the sides of the tail. The sexes are similar. Although its habitat is being fragmented, it is a common bird with a very wide range so the International Union for Conservation of Nature has assessed its conservation status as being of "least concern".

<span class="mw-page-title-main">Vermilion flycatcher</span> Species of bird in the Americas

The vermilion flycatcher is a small passerine bird in the tyrant flycatcher family found throughout South America and southern North America. It is a striking exception among the generally drab Tyrannidae due to its vermilion-red coloration. The males have bright red crowns, chests, and underparts, with brownish wings and tails. Females lack the vivid red coloration and can be hard to identify—they may be confused for the Say's phoebe. The vermilion flycatcher's song is a pit pit pit pidddrrrreeedrr, which is variable and important in establishing a territory. Riparian habitats and semi-open environments are preferred. As aerial insectivores, they catch their prey while flying. Their several months-long molt begins in summer.

<span class="mw-page-title-main">Rock firefinch</span> Species of bird

The rock firefinch is a species of estrildid finch found in the Jos Plateau of central Nigeria and in Cameroon. It has an estimated global extent of occurrence of 29,000 km2. The rock firefinch was discovered recently, in 1998. Rock firefinches fall in the family Estrildidae, which contains small passerine birds of the Old World and Australasia. Rock firefinches seem to be most closely related to Mali firefinches and Chad firefinches. The species name sanguinodorsalis means blood-red back, which was chosen because it describes the vibrant red back color of the male plumage. The status of the species is evaluated as Least Concern.

The Kentish plover is a small wader of the family Charadriidae that breeds on the shores of saline lakes, lagoons, and coasts, populating sand dunes, marshes, semi-arid desert, and tundra. Both male and female birds have pale plumages with a white underside, grey/brown back, dark legs and a dark bill; however, additionally the male birds also exhibit very dark incomplete breast bands, and dark markings either side of their head, therefore the Kentish plover is regarded as sexually dimorphic.

<span class="mw-page-title-main">Long-billed plover</span> Species of bird

The long-billed plover is a species of wading bird in the family Charadriidae. It can be found in Bangladesh, Bhutan, Brunei, Cambodia, China, Hong Kong, India, Indonesia, Japan, Laos, Malaysia, Mongolia, Myanmar, Nepal, North Korea, Russia, South Korea, Sri Lanka, Taiwan, Thailand, and Vietnam. The long-billed plover is a migratory bird, so it breeds and spends the winter in different parts of its range. This bird can often be spotted along the shores of rivers, streams, in wetlands, and rice fields. It forages on the shoreline primarily for aquatic insects, insect larvae, and other invertebrates. It is difficult to distinguish between male and female individuals because of their similar plumage. The breeding season starts at the end of February or early March and ends in July. A male and a female forms a monogamous pair and maintains their territory throughout the breeding season. A global population survey in 2016 assessed the long-billed plover as a species of least concern on the International Union for Conservation of Nature (IUCN) Red List.
