20-4-2018 OKAVANGO DELTA, BOTSWANA - ARID CROWNED LAPWING (Vanellus coronatus ssp. xerophilus)
Although generally outnumbered by blacksmith lapwings, they are the most widespread and locally the most numerous lapwing species in their area of distribution. Their numbers have increased in the latter part of the 20th century after benefiting from a range of human activities. They live up to 20 years.
The crowned lapwing is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) applies.
Their diet consists of a variety of insects, but termites and ants form an important component. These insects are often extracted from the dung of large mammals. They feed mainly by surface pecking as opposed to digging.

16-4-2018 CHOBE NATIONAL PARK, BOTSWANA - BURCHELL'S SANDGROUSE (Pterocles burchelli)
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.
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.
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. 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.
