Sandgrouse are birds of desert and dry scrub, their mottled brown plumage camouflaging them perfectly in the dusty landscape. It is a partial migrant, with some Asian birds moving to the Middle East and northern Pakistan in winter. Sandgrouse attend their nest as soon as the first egg is laid (Johnsgard, 1991), but incubation fully starts only after the last egg is laid (De Juana, 1997). 0000010380 00000 n 0000013321 00000 n 0000005429 00000 n There are two subspecies; P. a. alchata breeds in southern Europe and P. a. caudacutus breeds in northwestern Africa, the Middle East and southeastern Asia. When the female and chicks pick up the sounds of his approach, they reciprocate, and by this means the male can find his family even when they have moved away from the nest. 0000006442 00000 n [2], The species name alchata is thought to be derived from Arabic al-gata which is derived from the call of the bird. 0000150559 00000 n 0000011013 00000 n 0000151090 00000 n If a jackal approaches, an adult gives a warning cry and all crouch down and freeze.

Beetles and other small invertebrates are sometimes eaten and grit is consumed to help grind up the contents of the crop. When all is safe, another distinctive call from the sentinel bird sends all the others to the pool where their daily water needs are taken up within about fifteen seconds.
In Africa its range extends through Morocco, Algeria, Tunisia, Libya, Sudan, Egypt, Eritrea, Somalia, Ethiopia, Djibouti, Mali, Mauritania, Chad and Niger. 0000151741 00000 n Sandgrouse also avoid leaving the nest unattended during the hottest hours of the day (De Juana, 1997), when the nest temperature can increase dramatically, even during a short absence.
[5], Previously the crowned sandgroupse was included in genus Eremialector and recent studies suggest that it is part of a clade that also includes the yellow-throated sandgrouse P. gutturalis and the Madagascan sandgrouse P. personatus; and these may form a group along with the two Syrrhaptes species, black-bellied sandgrouse P. orientalis, Namaqua sandgrouse P. namaqua and chestnut-bellied sandgrouse P. exustus, and possibly including also P. alchata and P. burchelli; further study is required. [8], The journey to the waterhole is undertaken at around dawn when the air is cool. During a disturbance, we found that the incubating bird returned faster to its nests when the outside temperature was higher ( Fig. The eggs usually hatch after 20 – 25 days, and the hatchlings can leave the nest as soon as the last hatchling has dried out. 0000011174 00000 n 0000153620 00000 n 0000151592 00000 n 5 ), most likely to prevent an overheating of the clutch.

During disturbances, changes in nest temperatures depended on the changes in outside temperature, and negatively correlated with absence duration.

The crowned sandgrouse (Pterocles coronatus) is a species of bird in the sandgrouse family, the Pteroclidae from North Africa and the Middle East. Nesting success was low (19%), with no noticeable effect of data-loggers. Avoids areas with too much vegetation. When caring for the chicks, they will rub their bellies in the sand to remove the waterproofing oil and allow the feathers to soak up water (the feathers have a particular structure to allow this) and carry it back to the nest. The chin, neck and throat are orange and the breast grey.
According to some systems of classification, sandgrouse are ranked with the plovers within the order Charadriiformes. It has long pointed wings, which are white underneath, a long tail and a fast direct flight. Temperature data-loggers can provide an easy and effective way of monitoring nests, without the need of repeated nest visits. 0000008473 00000 n Eastern populations, particularly those from Kazakhstan, migrate to Pakistan and parts of northern India in winter.

On his arrival he assumes an upright posture and raises his wings, displaying the wet belly feathers. Meanwhile, the problem of supplying them with water is solved by the male which has specially adapted, absorbent down on his belly.

The general colouring is cryptic, a blend of barred and flecked olive green, brown, buff, yellow, grey and black.

[11], If danger threatens, the chicks crouch under a plant or any cover that offers, their dappled brown down merging into the desert scene. Their chief enemy is the lanner falcon which flies rapidly just above the ground and scoops up any unwary bird. It does not occur at elevations above about 1,000 metres (3,300 ft). [4] The chicks are able to feed themselves by the age of a week and can fly by the time they are four weeks old. [6] The birds are very wary and easily frightened. This monogamous bird lays eggs all year around, but the laying does tend to peak at certain times, depending on the area in which the sandgrouse … 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. They may have to fly twenty miles or more in search of a water hole to drink, where they can gather in flocks of thousands.
