Glareola pratincola
SUBFAMILY
Glareolinae
TAXONOMY
Hirundo pratincola Linnaeus, 1766, Austria. Three subspecies
recognized.
OTHER COMMON NAMES
English: Common pratincole, red-winged pratincole, locust
bird, swallow-plover; French: Glarйole а collier; German: Rotflьgel
Brachschwalbe; Spanish: Canastera Comъn.
PHYSICAL CHARACTERISTICS
8.7–9.8 in (22–25 cm); 2.1–3.7 oz (60–104 g). Slender, shortlegged,
long-winged; plumage mostly smoky grayish brown
shading to white on belly. Throat yellowish buff surrounded by
narrow black collar (absent when not breeding). Bill red at base
and around gape. Underwing coverts dull rusty brown to
chestnut.
DISTRIBUTION
The most widespread of the pratincoles. Breeding populations
are scattered discontinuously throughout sub-Saharan Africa
and Eurasia from Spain to Lake Balkhash in Kazakhstan. Nonbreeding
birds migrate to sub-Saharan Africa.
HABITAT
Istvбn Sterbetz describes the habitat as the zone between
short-grass steppes and desert, as well as floodplains, dried estuarine
mud banks, and marine shore with semi-desert
features.
BEHAVIOR
Collared pratincoles are highly gregarious at all times, even
when breeding. They spend much time resting on the ground
between bouts of aerial feeding. They tend to be vocal, especially
in breeding colonies and on migration. Their flight is
buoyant.
FEEDING ECOLOGY AND DIET
Catch flying insects on the wing and chase prey on the ground
by running or by a short leap into the air. Food is mainly
grasshoppers and beetles; during locust plagues, flocks of pratincoles
devour large numbers of these insects.
REPRODUCTIVE BIOLOGY
Breeds in spring in the Northern Hemisphere, in the dry season
in most of tropical Africa and in early summer in southern
Africa; breeding is usually in loose colonies. The nest is a shallow
scrape, sometimes lined with a few bits of earth or dry
plant fragments. The clutch in Eurasia is usually three eggs,
but only two in Africa. The eggs are whitish to cream, heavily
blotched with black, gray, and brown. Both sexes incubate for
17–19 days, and feed the precocial chicks for at least a week.
The young fly at the age of about a month.
CONSERVATION STATUS
Though not globally threatened, collared pratincoles have declined
in numbers in Europe and parts of Africa as a result of
pesticides, artificial fertilizers, habitat destruction, and disturbance,
especially of breeding colonies. Breeding sites need
protection.
SIGNIFICANCE TO HUMANS
Apart from the commercial collecting of eggs, the collared
pratincole has little
SIGNIFICANCE TO HUMANS
. In the past it probably
helped to control locust plagues, but the decline in numbers
reduces the birds’ impact in this regard.
