Burchell's sandgrouse (Pterocles burchelli) is a species of bird in the family Pteroclidae. It is found in arid and semi-arid regions of southern Africa. The name of this bird commemorates the English naturalist William John Burchell. [2]

Description

Burchell's sandgrouse is a plump bird about the size of a pigeon with a small head and short legs. The body is light brown, mottled with darker shades and white speckles. In males, the eye is surrounded by bare yellow skin and the cheeks and throat are pale grey. The male grows to about 25 cm (10 in) long and the female is a little smaller. [3]

Burchell's sandgrouse is limited by water availability, like many of the other species residing in arid desert environments. Adult sandgrouse increase gular fluttering and panting for evaporative cooling when approaching the upper critical limit of their thermal neutral zone around 43.8 °C. [4] Another adaptation that adult Burchell's sandgrouse have developed is the transport of water in body feathers from a water source back to the nest to water their chicks. [5] Upon arriving at a water source, adult Burchell's sandgrouse first rub their bellies on dry ground to ruffle up their belly feathers, increasing the amount of water the feathers can hold. They then wade into the water and bob up and down on a horizontal axis to soak up the water in their belly feathers. Males have been observed to hold an average of 22 ml of water, while females can carry an average of 9 ml. Once the water is gathered, Burchell's sandgrouse fly back to the nest and allow their chicks to drink water from their belly feathers.

Distribution and habitat

Burchell's sandgrouse is found in Angola, Namibia, Botswana, Zambia, Zimbabwe and South Africa. It is normally resident but moves about to a limited extent depending on the availability of water and the seeds it mainly eats. It is widespread and common in much of its range. [6] It frequents areas of rough grass and scrub, especially on red Kalahari sand and has been able to extend its range because of the greater availability of water after the sinking of boreholes by farmers. [7]

Breeding

Burchell's sandgrouse is monogamous and breeds during the dry season between April and October. The nest is formed in a shallow depression in the ground often concealed among grass tussocks or under a bush. It is lined with a few fragments of dry vegetation and two or usually three eggs are laid. Both parents incubate the eggs and the chicks are precocial when they hatch, covered in down and soon able to run after the adult birds. Both parents care for the young and, as in other sandgrouse species, water is brought to them absorbed in the specially adapted feathers that line the parents' breasts. [7]

Sandgrouse is the common name for Pteroclidae, a family of sixteen species of bird, members of the order Pterocliformes. They are traditionally placed in two genera. The two central Asian species are classified as Syrrhaptes and the other fourteen species, from Africa and Asia, are placed in the genus Pterocles. They are ground-dwelling birds restricted to treeless, open country, such as plains, savannahs, and semi-deserts. They are distributed across northern, southern, and eastern Africa, Madagascar, the Middle East, and India through central Asia. The ranges of the black-bellied sandgrouse and the pin-tailed sandgrouse even extend into the Iberian Peninsula and France, and Pallas's sandgrouse occasionally breaks out in large numbers from its normal range in Asia.

The pin-tailed sandgrouse is a medium large bird in the sandgrouse family. It has a small, pigeon like head and neck and a sturdy, compact body. It has long pointed wings, which are white underneath, a long tail and a fast direct flight. Flocks fly to watering holes at dawn. The call is a loud kattar-kattar. This gregarious species breeds on dry open treeless plains and similar habitats. Its nest is a ground scrape into which two or three cream-coloured eggs with cryptic markings are laid. Both sexes incubate the eggs.

The eastern bluebonnet, also known as the greater bluebonnet, is an Australian parrot, one of two species in the genus Northiella. It was originally included in the genus Psephotus but due to distinctive physical and behavioural differences was reclassified into its own genus in 1994 by ornithologists and taxonomists Christidis and Boles. The bluebonnet is a medium-sized inland parrot commonly found in the interior of southeastern and central-southern Australia. It is adapted to life in semi-arid regions but can also flourish in regions of medium rainfall towards the eastern and southern extremities of its range.

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.

It is found in arid regions of northern and eastern Africa and across the Middle East and parts of Asia as far east as northwest India. It is a gregarious, diurnal bird and small flocks forage for seed and other vegetable matter on the ground, flying once a day to a waterhole for water. In the breeding season pairs nest apart from one another, the eggs being laid in a depression on the stony ground. The chicks leave the nest soon after hatching and eat dry seed, the water they need being provided by the male which saturates its belly feathers with water at the waterhole. The spotted sandgrouse is listed as being of "least concern" by the International Union for Conservation of Nature in its Red List of Threatened Species.

It is a medium-sized nomadic shorebird which is commonly found in arid inland Australia. It breeds predominantly from south-western Queensland to northern Victoria and through central Australia to the Kimberley region in Western Australia. The Australian population is estimated at 60,000 individuals. They are a migratory species that generally move to the southern parts of their distribution range to breed during spring and summer. During winter they migrate to northern Australia, New Guinea, Java, Sulawesi and southern Borneo to over-winter. Although they are common, their occurrence is unpredictable and varies in location.
