Summary
| Description |
Porphyrio alleni, Pendjari NP, Benin Français : Omnivore, il se nourrit de fleurs, de graines, de feuilles, de fruits, de vers de terre, de mollusque, de crustacés, d'insectes, d'araignées, de petits poissons et de leur œufs.
Les talèves d'Allen sont des oiseaux assez secrets. D'après le peu de renseignements qui ont pu être collectés en afrique, elles sont surtout observables pendant les deux premières heures du jour, après quoi elles se retirent sous le couvert épais. Sur toute l'étendue de leur aire, elles sont considérées comme erratiques, c'est à dire des habitants intermittents ou irréguliers. Elle nagent volontiers, mais si elles se sentent en danger, elles s'enfuient à couvert en courant, tête baissée et queue relevée, exhibant leurs sous caudales. Lorsqu'elles décollent, leur vol est bref et on aperçoit leurs longues pattes et leurs longs doigts qui pendillent derrière la queue. Le nid est une construction d'herbes et de roseaux qui a la forme d'une boule surmontée d'un dôme. Il est généralement suspendu à une faible hauteur au-dessus de l'eau. Il s'agit même parfois d'un nid flottant dans lequel la femelle dépose 2 à 5 oeufs. On ne possède pas de renseignements sur la durée d'incubation et de séjour au nid. On présume que, comme chez la plupart des rallidés, les petits sont nidifuges. Cette image a été prise dans la Forêts classées d'ouémé supérieur au nord du paysEnglish: Allen's gallinules are omnivorous, feeding on flowers, seeds, leaves, fruit, worms, molluscs, crustaceans, insects, spiders, small fish and their eggs. They are pretty secretive birds. According to the little information that has been collected in Africa, they are mostly observable during the first two hours of the day, after which they retreat to thick cover.
Throughout their area, they are considered erratic, i.e. intermittent or irregular inhabitants. They swim willingly, but if they feel in danger, they run away under cover, head down and tail up, showing off their underside caudals. When they take off, their flight is brief and we see their long legs and their long toes dangling behind the tail. The nest is constructed of grass and reeds in the shape of a ball topped with a dome. It is usually suspended at a low height above the water. It is sometimes even a floating nest in which the female lays 2 to 5 eggs. There is no information on incubation and nesting time. It is assumed that, as with most rallids, juveniles are nidifuges.
