Tristram's starling (Onychognathus tristramii), also known as Dead Sea starling or Tristram's grackle, is a species of starling native to the Middle East. It is the only member of the genus Onychognathus found mainly outside of Africa. [2] The species is named after Reverend Henry Baker Tristram, who collected natural history specimens. [3]
This bird is found in deserts in Israel, Jordan, northeastern Egypt (Sinai Peninsula), western Saudi Arabia, Yemen, and Oman, nesting mainly on rocky cliff faces. The species is becoming increasingly commensal with humans, feeding in towns and villages; this has enabled a recent northward spread in its distribution. [4]
Tristram's starling is 25 cm long (including a 9 cm tail), with a wingspan of 44–45 cm, and a weight of 100–140 g. The males have glossy iridescent black plumage with orange patches on the outer wing, which are particularly noticeable in flight. The bill and legs are black. Females and young birds are similar but duller and with a greyish head, lacking the plumage gloss. [4] [5]
Although starlings are a tropical family by origin, Tristram's starling is well adapted to living in a desert environment: it loses relatively little water to evaporation and produces less heat than expected for its base metabolic rate. Its dark plumage may help it survive in the desert winter, when temperatures are low but the Sun's radiation is strong. [6]
Tristram's starlings are omnivorous, feeding on fruit and invertebrates (mainly insects such as beetles, flies, butterflies, and bees; but also small snails [7] ). They have also been observed grooming Nubian ibex and domestic livestock for parasites. [2] Although they do not migrate for the most part, [8] they fly relatively long distances compared to other resident birds, which likely makes them important seed dispersers for fleshy-fruited desert plants. [9] In addition, they often forage for scraps in human settlements. [7]
Tristram's starlings breed during the spring and early summer. They nest in existing cavities in rocky cliffs and also in urban buildings. [8] Pairs are monogamous. The male courts the female by bringing her insects and twigs. They lay 2-4 eggs, which are blue with brown spots. [7] Females incubate alone, [10] but both parents feed the chicks. The young leave the nest about a month after hatching. [7] Some pairs raise a second brood in later in the season, using the same nest. [2]
Tristram's starling is a gregarious and noisy bird, with a call that resembles a wolf whistle. Outside the breeding season the starlings live in groups of between ten and a few hundred individuals. [8] However, pairs remain together throughout the year, even when they join a larger group. [2]
The common blackbird is a species of true thrush. It is also called the Eurasian blackbird, or simply the blackbird where this does not lead to confusion with a similar-looking local species. It breeds in Europe, western Asia, and North Africa, and has been introduced to Australia and New Zealand. It has a number of subspecies across its large range; a few former Asian subspecies are now widely treated as separate species. Depending on latitude, the common blackbird may be resident, partially migratory, or fully migratory.
The crab-plover or crab plover is a bird related to the waders, but sufficiently distinctive to merit its own family Dromadidae. Its relationship within the Charadriiformes is unclear, some have considered it to be closely related to the thick-knees, or the pratincoles, while others have considered it closer to the auks and gulls. It is the only member of the genus Dromas and is unique among waders in making use of ground warmth to aid incubation of the eggs.
Starlings are small to medium-sized passerine birds in the family Sturnidae. The Sturnidae are named for the genus Sturnus, which in turn comes from the Latin word for starling, sturnus. The family contains 128 species which are divided into 36 genera. Many Asian species, particularly the larger ones, are called mynas, and many African species are known as glossy starlings because of their iridescent plumage. Starlings are native to Europe, Asia, and Africa, as well as northern Australia and the islands of the tropical Pacific. Several European and Asian species have been introduced to these areas, as well as North America, Hawaii, and New Zealand, where they generally compete for habitats with native birds and are considered to be invasive species. The starling species familiar to most people in Europe and North America is the common starling, and throughout much of Asia and the Pacific, the common myna is indeed common.
The common starling, also known as the European starling in North America and simply as the starling in Great Britain and Ireland, is a medium-sized passerine bird in the starling family, Sturnidae. It is about 20 cm (8 in) long and has glossy black plumage with a metallic sheen, which is speckled with white at some times of year. The legs are pink and the bill is black in winter and yellow in summer; young birds have browner plumage than the adults. It is a noisy bird, especially in communal roosts and other gregarious situations, with an unmusical but varied song. Its gift for mimicry has been noted in literature including the Mabinogion and the works of Pliny the Elder and William Shakespeare.
There are seven species of Australasian treecreeper in the passerine bird family Climacteridae. They are medium-small, mostly brown birds with patterning on their underparts, and all are endemic to Australia-New Guinea. They resemble, but are not closely related to, the Holarctic treecreepers. The family is one of several families identified by DNA–DNA hybridisation studies to be part of the Australo-Papuan songbird radiation. There is some molecular support for suggesting that their closest relatives are the large lyrebirds.
The chipping sparrow is a species of New World sparrow, a passerine bird in the family Passerellidae. It is widespread, fairly tame, and common across most of its North American range.
The red-headed woodpecker is a mid-sized woodpecker found in temperate North America. Its breeding habitat is open country across southern Canada and the east-central United States. It is rated as least concern on the International Union for Conservation of Nature (IUCN)'s Red List of Endangered species, having been down-listed from near threatened in 2018.
The purple sunbird is a small bird in the sunbird family found mainly in South and Southeast Asia but extending west into parts of the Arabian peninsula. Like other sunbirds they feed mainly on nectar, although they will also take insects, especially when feeding young. They have a fast and direct flight and can take nectar by hovering like a hummingbird but often perch at the base of flowers. The males can appear all black in harsh sunlight but the purple iridescence is visible on closer observation or under good light conditions. Females are olive above and yellowish below.
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".
The blackstart is a chat found in desert regions in North Africa, the Middle East and the Arabian Peninsula. It is resident throughout its range.
The Nubian ibex is a desert-dwelling goat species found in mountainous areas of northern and northeast Africa, and the Middle East. It was historically considered to be a subspecies of the Alpine ibex, but is now considered a distinct species. The wild population is estimated at 4,500 mature individuals, and it is classified as vulnerable.
Grackles is the common name of any of 11 passerine birds native to North and South America. They belong to various genera in the icterid family. In all the species with this name, adult males have black or mostly black plumage. Baby birds like to feed by screeching.
The red-winged starling is a bird of the starling family Sturnidae native to eastern Africa from Ethiopia to the Cape in South Africa. An omnivorous, generalist species, it prefers cliffs and mountainous areas for nesting, and has moved into cities and towns due to similarity to its original habitat.
The brown treecreeper is the largest Australasian treecreeper. The bird, endemic to eastern Australia, has a broad distribution, occupying areas from Cape York, Queensland, throughout New South Wales and Victoria to Port Augusta and the Flinders Ranges, South Australia. Prevalent nowadays between 16˚S and 38˚S, the population has contracted from the edges of its pre-European range, declining in Adelaide and Cape York. Found in a diverse range of habitats varying from coastal forests to mallee shrub-lands, the brown treecreeper often occupies eucalypt-dominated woodland habitats up to 1,000 metres (3,300 ft), avoiding areas with a dense shrubby understorey.
The oriental pied hornbill is an Indo-Malayan pied hornbill, a large canopy-dwelling bird belonging to the family Bucerotidae. Two other common names for this species are Sunda pied hornbill (convexus) and Malaysian pied hornbill.
Hildebrandt's starling is a species of starling in the family Sturnidae. It forms a superspecies with and has previously been included in the same species as Shelley's starling, a migratory species ranging from Ethiopia and Somalia to Kenya. Both of these species have also been combined into a superspecies with the chestnut-bellied starling of West Africa. It was originally placed in the now defunct genus Notauges. The species is named for Johann Maria Hildebrandt, a German collector who was the first European to obtain specimens.
Onychognathus is a genus of starlings, most of which are found in Africa.
The black-collared starling is a species of starling in the family Sturnidae. Its plumage is black and white, with a black collar. It is found in southern China and most of mainland Southeast Asia, and has been introduced to Taiwan, Malaysia and Singapore. Its habitats include grassland, dry forest and human settlements. The International Union for Conservation of Nature (IUCN) has assessed it as being of least concern.
Neumann's starling or Neumann's red-winged starling, is a bird native to Africa. This starling breeds on rocky cliffs, outcrops and gorges mainly in the Sahel from Mauritania and Equatorial Guinea to western Sudan. Its English and binomial names commemorate German ornithologist Oscar Rudolph Neumann.
Golden eagles usually mate for life. A breeding pair is formed in a courtship display. This courtship includes undulating displays by both in the pair, with the male bird picking up a piece of rock and dropping it only to enter into a steep dive and catch it in mid-air, repeating the maneuver 3 or more times. The female takes a clump of earth and drops and catches it in the same fashion. Small sticks may also be used in this display. Compared to the bald eagle, golden eagles do not repeat courtship displays annually and rarely engage in talon-locking downward spirals.
