How does the Jacana's surface foraging strategy contrast with that of ducks or moorhens?

Answer

The jacana utilizes the floating plant matter as a stable platform from which to hunt and glean, unlike birds that dabble or dive.

The Wattled Jacana occupies a specific trophic layer identified as the "floating surface grazer." Its primary method involves using floating vegetation, like lily pads, not just as a food source but as a crucial, stable substrate or platform upon which to balance while foraging. This differs significantly from ducks, which typically dabble in shallow water, or moorhens, which swim and dive beneath the surface. By operating exclusively on this unstable, shifting platform, the jacana effectively avoids direct feeding competition with wading birds like herons, which hunt in deeper water, and terrestrial insectivores foraging along the banks.
