Immature: Similar to adult Lesser Jacana, but much bigger; above light brown (dark brown in adult Lesser Jacana), below white; breast washed golden (no gold in adult Lesser Jacana); flanks brown; frontal shield small (not visible in field); crown and hind neck blackish brown (crown rufous in adult Lesser Jacana); black line through eye; buff eyebrow (eyebrow of adult Lesser Jacana white, forehead buff). Measurements: Length 25-30 cm; wing 143-156-180; tail 38-56; tarsus 56-68; culmen 47-58 (variable in size; female usually bigger than male). Weight (male) 115-132,8-162 g, (female) 176-238,3-274 g.

Taxonomy
Habitat
Behaviour
The African Jacana (Actophilornis africana) is a jacana. The jacanas are a group of waders in the family Charadriidae, which are identifiable by their huge feet and claws which enable them to walk on floating vegetation in the shallow lakes that are their preferred habitat. African Jacana breeds throughout sub-Saharan Africa. It is sedentary apart from seasonal dispersion. It lays four black-marked brown eggs in a floating nest. The males, as in some other wader families like the phalaropes, take responsibility for incubation.
