African Jacana (Actophilornis africanus) is the common species on the shores of Lake Baringo,one will therefore understand my excitement with the sighting of Lesser Jacana is this area, a new thing for us.In birding we like that element of surprises!. My thinking is that the current flooding experienced in the Lake as encouraged this species to venture out.
Lesser Jacanan is the smallest of all Jacanas in the planet.Females are larger than males;infact in some species,they weigh two-third more.Jacanas sometimes described as lilytrotters are colourful,long-legged water birds that resemble rails and are found almost exclusively in tropical regions.Their long,spidery toes enables them to walk easily over lily pads or other floating plants,giving them the appearances of walking on water.
The species spend long periods foraging in aquatic vegetation.It prefer wetland habitat;also reedbed,swamp,and areas of deeper water with suitable surface cover.Occasionally,the birds are also seen in fields and agricultural areas near wetland.
With the only exception of Lesser Jacana, Jacanas are polyandrous in nature(female mate with more than one male) and they also exhibit sex-role reversal.Males tend the nest and care for chicks while the larger, more aggressive females defend the territory from predators. Researchers have theorized that jacanas may have evolved with this unorthodox system to compensate for a high rate of egg and chick loss, which typically is greater than 50% due to their unstable aquatic habitat and attacks by water snakes, turtles, and larger birds.
If females can spend less time sitting on the nest and more time mating with multiple partners, scientists argue, they can lay more eggs and contribute to the overall success of the species.
Other than this an expected sighting, Lesser Jacana are found in Kenya highlands wetland lands,ponds and man-made dams.
