For the conservation of these bird species, a Mangrove Finch Project is being carried out. The Mangrove Flinch Project is carried out by institutions such as Charles Darwin Foundation and several other trusts and funds.

How do they reproduce?

Mangrove finches, also known as Darwin's Finches, have their breeding season between the months of December to April. In the breeding season, the male birds keep their hold on a specific territory which may last for a year. Then with the help of their song, they attract the female birds, and the breeding begins. Generally, the male and female birds together make their nest on the canopy. After all these processes, the female lays three to four eggs which go through an incubation period of around two weeks. The nestlings take some days to become young and independent. But even after that, the young birds tend to follow their parents for some weeks.

According to the IUCN Red List, the mangrove finch is classified as a Critically Endangered species with a population count of less than 100 at present. For their conservation, many institutions, firms, and trusts such as the Charles Darwin Foundation have started the Mangrove Finch Project.

According to the evolution theory, the finch species with bigger beaks survived. Bigger beaks gave them easier access to food. According to Darwin, the beak of the ancestral species evolved to different sizes so that different finch species could access different food sources.

To gradually reduce and finally check this population downfall, the Charles Darwin Foundation is working sincerely towards their conservation by several acts such as giving these birds the environment to breed, protecting the eggs and young ones from getting killed by their natural predators, providing healthcare, and a lot more.
