Why is the jacana a species of Least Concern?

According to the International Union for Conservation of Nature Red List, the jacana is declared as the species of Least Concern because of its stable population. One unique characteristic of these birds is that they are polyandrous in nature which means the females mate with more than one male. This breeding system is not very common among birds.

What are the 8 species of Jacanidae?

Do jacanas walk on water?
