The Barbary dove, ringed turtle dove, ringneck dove, ring-necked turtle dove, or ring dove (Streptopelia risoria) is a domestic member of the dove and pigeon family (Columbidae).
Although the Barbary dove is normally assigned its own systematic name, as Streptopelia risoria, considerable doubt exists as to its appropriate classification. Some sources assert confidently that it is a domesticated form of the Eurasian collared dove (Streptopelia decaocto), but the majority of evidence points to it being a domesticated form of the African collared dove (Streptopelia roseogrisea).[ citation needed ]
It appears that it can hybridize freely with either species, and its status as a species must therefore be regarded as doubtful. However, because of the wide use of both the common and systematic names, it is best to consider it separately from either of the parent species. Their time of domestication is also uncertain. While Linnaeus described them in 1756, they may have been imported into Italy from North Africa in the late 16th century. [1]
Barbary doves are easily kept and long-lived in captivity, living for up to 12 years. There have been cases of doves living over 20 years, [2] and, in one case, of a dove living for 29 years. [3] In recent years they have been used extensively in biological research, particularly into the hormonal bases of reproductive behaviour, because their sequences of courtship, mating and parental behaviour have been described accurately and are highly consistent in form. Dove fanciers have bred them in a great variety of colours; the number of colours available has increased dramatically in the latter half of the 20th century, and it is thought that this has been achieved by interbreeding with Streptopelia roseogrisea.
Some of these doves carry a mutation that makes them completely white. These white Barbary doves are most commonly used in stage magic acts. White Barbary doves are also traditionally released in large public ceremonies, since it is a peace symbol in several cultures, and "dove releases" are also sometimes found at weddings and funerals. However, a release dove is, in fact, usually a homing pigeon, as Barbary doves lack the homing instinct.
The coo of the Barbary dove is created by muscles that vibrate air sent up from the dove's lungs. These muscles belong to the fastest known class of vertebrate muscles, contracting as much as 10 times faster than muscles vertebrates use for running. This class of muscles is usually found in high speed tissue such as a rattlesnake's tail. Barbary doves are the first bird species to have been found to have this class of muscle. [4]
They can be crossed with the pigeon to create offspring, but the offspring are not fertile. [5] [6]
Columbidae is a bird family consisting of doves and pigeons. It is the only family in the order Columbiformes. These are stout-bodied birds with short necks and short slender bills that in some species feature fleshy ceres. They primarily feed on plants, and can be taxonomically divided amongst granivores, that feed mostly on the ground on seeds, and frugivores, that feed mostly on fruits, from branches. The family occurs worldwide, often in close proximity with humans, but the greatest variety is in the Indomalayan and Australasian realms.
The rock dove, rock pigeon, or common pigeon is a member of the bird family Columbidae. In common usage, it is often simply referred to as the "pigeon", although this is the wild form of the bird; the pigeons most familiar to people are the domesticated form of the wild rock dove.
The European turtle dove is a threatened or vulnerable member of the bird family Columbidae, the doves and pigeons. It breeds over a wide area of the south western Palearctic including north Africa but migrates to northern sub-Saharan Africa to winter.
The Eurasian collared dove, often simply just collared dove, is a dove species native to Europe, Asia, and northern Africa. It has also been introduced to Japan, North and Central America, and the islands in the Caribbean.
The Oriental turtle dove or rufous turtle dove is a member of the bird family Columbidae. The species has a wide native distribution range from Central Asia east across Asia to Japan. The populations show variations in the patterning of plumage and have been designated into at least six named subspecies. Populations in the higher latitudes tend to migrate south in winter, while those closer to the tropics are sedentary. Vagrants have been recorded in North America. The species is predominantly granivorous and forages on the ground.
The African collared dove is a small dove found in the Sahel, northern parts of the Horn of Africa and southwestern Arabia. Although it lives in arid lands, it is found around water sources.
The bird genus Columba comprises a genus of medium to large pigeons. The terms "dove" and "pigeon" are used indiscriminately for smaller and larger Columbidae, respectively. Columba species are mostly termed "pigeons", and in many cases "wood pigeons", but some, are termed "doves". The rock dove has given rise to the majority of domesticated pigeon breeds, such as the racing pigeon and the fantail pigeon, some of which have become feral. Meanwhile, "wood pigeon" by itself usually means the common wood pigeon.
The spotted dove or eastern spotted dove is a small and somewhat long-tailed pigeon that is a common resident breeding bird across its native range on the Indian subcontinent and in East and Southeast Asia. The species has been introduced to many parts of the world and feral populations have become established.
Streptopelia is a genus of 15 species of birds in the pigeon and dove family Columbidae native to the Old World in Africa, Europe, and Asia. These are mainly slim, small to medium-sized species. The upperparts tend to be buffy brown and the underparts are often a shade of pinkish-brown, and they have a characteristic black-and-white patch on the neck. They have cooing or purring songs, monotonous in some, restful and soothing in others. The genus divides into two groups, the collared dove group with uniform upperparts and a black half-collar edged with white, and the turtle dove group with patterned upperparts and a barred side panel on the neck. They range in size from the 20–23 cm red collared dove to the 33–35 cm oriental turtle dove. Most of the species are resident or disperse over short distances, but two are long-distance migrants breeding in temperate areas and wintering in the tropics. The sexes are not differentiated in most of the species, except for the red collared dove, where the males are orange-red with a greyish head, and the females a duller brown.
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.
The domestic pigeon is a pigeon subspecies that was derived from the rock dove or rock pigeon. The rock pigeon is the world's oldest domesticated bird. Mesopotamian cuneiform tablets mention the domestication of pigeons more than 5,000 years ago, as do Egyptian hieroglyphics. Pigeons were most likely domesticated in the Mediterranean at least 2000–5000 years ago, and may have been domesticated earlier as a food source. Research suggests that domestication of pigeons occurred as early as 10,000 years ago.
The red collared dove, also known as the red turtle dove, is a small pigeon which is a resident breeding bird in the tropics of Asia. The male has a blue-grey head and a red-brown body. The female is much plainer, with pale brown plumage similar to that of the larger Eurasian collared dove.
The Réunion pink pigeon is an extinct subspecies of pigeon that formerly lived on the Mascarene island of Réunion. It is known from the description of a rusty-red pigeon given by Dubois in 1674 and a single subfossil humerus that agrees with that of the pink pigeon of Mauritius in generic characteristics, except being slightly longer. Also, Dubois' reference to the bill being red at the base and the eyes being surrounded by a red ring suggest that this species was closely allied to the Mauritius taxon. Dubois' description was as follows:
wild pigeons, everywhere full with them, some with slaty-coloured feathering [Alectroenas?], the others russet-red [N. duboisi]. They are a little larger than the European pigeons, and have larger bills, red at the end close to the head, the eyes ringed with the colour of fire, like pheasants. There is a season when they are so fat that one can no longer see their cloaca [croupion]. They are very good tasting. Wood-pigeons and turtle-doves, as one sees in Europe and as good.
A release dove is usually a small white domestic rock dove used for events such as public ceremonies, weddings and funerals. They typically have a symbolic meaning for the event.
Ring dove is an alternative name for the Barbary dove. It may also refer to:
Nesoenas is a bird genus in the pigeon and dove family, Columbidae. It is often included with the typical turtle-doves in Streptopelia or the typical pigeons (Columba). By those who accepted it, it was usually treated as monotypic, containing only the pink pigeon of Mauritius.
The Sunda collared dove, sometimes referred to as the island collared dove, Javanese turtle dove, Javanese collared dove, or Indonesian collared dove, is a species of bird in the family Columbidae. Sometimes confused with the Eurasian collared dove which is very similar in appearance, the Sunda collared dove is a small to medium-sized bird, native to the tropical and subtropical islands of Indonesia.
The Adamawa turtle dove is a species of bird in the pigeon and dove family Columbidae. It is also known as the pink-bellied turtle dove. The species is closely related to and has been considered the same species as the dusky turtle dove. The species has a disjunct distribution, being native to Cameroon, Nigeria and southwestern Chad and further west in Gambia, Senegal and Mali. It has also been reported defending a territory in Togo, suggesting a population may exist there too.
In birds, sleep consists of "periods of eye closure interrupted by short periods of eye-opening." During the short periods of eye-opening, electroencephalographic (EEG) studies indicate that the birds are still sleeping; the voltage level in the brain is identical. Birds restore their arousal thresholds during sleep. During their short eye-open periods, sleeping birds can mobilize almost instantaneously when threatened by a predator. Avian species have been found to rely on flock size and height for predatory precautions. Between the eye-opening and group sleep, these precautions allow sleep to be beneficial and safe.
