Encyclopedia
The Cream-colored Courser, Cursorius cursor, is a wader
in the pratincole
and courser
family, Glareolidae
.
Although classed as wader
s, these are bird
s of dry open country, preferably semi-desert, where they typically hunt their insect
prey by running on the ground.
These coursers are found in Canary Islands
, north Africa
and southwest Asia
. Their two eggs are laid in a ground scrape. They are partially migratory
, with northern and northwestern birds wintering in India
, Arabia
and across the southern edge of the Sahara
. Some birds also breed in the southern desert regions in northwestern India and Pakistan.
They are rare north of the breeding range, but this species has occurred as far away as Finland
, Ireland
and Great Britain
.
These bird
s have long legs and long wings. They have slightly downcurved bills. The body plumage is sandy in colour, fading to whitish on the lower belly. The upperwing primary feathers and the underwings are black. The crown and nape are grey, and there is a black eyestripe and white supercilium.
In flight this species resembles a pratincole, with its relaxed wingbeats, pointed wings and dark underwings.
This standard text treats the east African form littoralis as a race of the Somali Courser
rather than of Cream-colored. Some authorities in turn consider the Somali
, Burchell's
and Cream-colored coursers to be conspecific.
