Whilst out on the Delta swamps of Botswana, this great big stork came flying overhead.
This is a huge bird that regularly attains a height of 150 cm (59 in), a length of 142 cm (56 in) and a 2.4–2.7 m (7.9–8.9 ft) wingspan. The male is larger and heavier than the female, with a range of 5.1–7.52 kg (11.2–16.6 lb), with a mean mass of 6.38 kg (14.1 lb). The female is usually between 5 and 6.84 kg (11.0 and 15.1 lb), with a mean mass of 5.95 kg (13.1 lb). It is probably the tallest of the storks (though not the heaviest), due in no small part to it extremely long legs (tarsus length is up to 36.5 cm (14.4 in)). The long bill measures from 27.3 to 36 cm (10.7 to 14.2 in). The sexes can be readily distinguished by the golden yellow of the female and the brown irises and dangling yellow wattles of the male.
It is spectacularly plumaged; both the female and male appear identical when perched but the female shows much more white in the primaries in flight. The head, neck, back, wings, and tail are iridescent black, with the rest of the body and the primary flight feathers being white. Juveniles are browner grey in plumage. The massive bill is red with a black band and a yellow frontal shield (the “saddle”). The legs and feet are black with pink hocks. On the chest is a bare red patch of skin, whose colour darkens during breeding season
They are silent except for bill-clattering at the nest. Like most storks, these fly with the neck outstretched, not retracted like a heron; in flight, the large heavy bill is kept drooping somewhat below belly height, giving these birds a very unusual appearance to those who see them for the first time. To experienced birdwatchers on the other hand, this makes them easily recognizable even if seen from a distance. It has been suggested that due to the large size and unusual appearance in flight, this species is the basis for the “big bird” and kongamato cryptids.
Sometimes called a ‘swamp’, the Okavango is anything but. Moving, mysterious, placid, gentle and beautiful, from a wide and winding channel it spreads through tiny, almost unnoticeable channels that creep away behind a wall of papyrus reed, into an ever expanding network of increasingly smaller passages.
These link a succession of lagoons, islands and islets of various sizes, open grasslands and flooded plains in a mosaic of land and water. Palms and towering trees abound, throwing their shade over crystal pools, forest glades and grassy knolls.
The Okavango Delta is a vast inland river delta in northern Botswana. It’s known for its sprawling grassy plains, which flood seasonally, becoming a lush animal habitat. The Moremi Game Reserve occupies the east and central areas of the region. Here, dugout canoes are used to navigate past hippos, elephants and crocodiles. On dry land, wildlife includes lions, leopards, giraffes and rhinos. However, the bird life in these regions are equally rich in diversity.
