Let’s save the Harpies (Harpyja)

Harpies are in danger of extinction and their only predator is “Human Beings.” The devastation of the forests contributes to this, as well as the legend about harpies that steal and kill babies. This eagle is considered by experts to be the strongest bird that exists.

The harpy eagle (Harpia harpyja) is a bird of prey that lives naturally throughout the region of the international corridor that covers areas of the Atlantic Forest and possibly the Pantanal, also in the Seasonal Forest in Paraguay and Argentina, and can reach 20 kg and a wingspan almost 3 meters. It is currently classified as near threatened by the International Union for Nature Conservation.

Green Farm CO2Free works tirelessly to rehabilitate and restore these populations, through genetic variability banks, we also have an agreement with Itaipú binacional, and they have the first book of records of the Harpia Eagles in Brazil, Itaipú Binacional has the largest number of specimens, I think Fazenda Porto Bonito is the only private partner in the region.

In Greek mythology, the harpy was half human and half bird. Due to their size, they can hunt sloths and monkeys, as well as other birds and reptiles.

A century ago it was estimated that there were between 20 and 50 thousand throughout the country. the world. However, due to the loss of natural habitats, today they suffer the imminent risk of extinction and it is believed that there are around 5 thousand of these birds in the Atlantic Forest and Pantanal regions.

These birds have white and gray plumage, with a tuft of feathers on the top of the head, giving the animal a more intimidating still image.

They are monogamous animals, which means they only have one partner. During life. Additionally, they reproduce every two or three years. The clutch usually has one egg, but can contain up to one. year for a chick to fly and leave the nest. For this reason, it is especially difficult for the wild harpy population to increase naturally and tree felling can also destroy birds’ nests, killing chicks.

In Brazil, the project Green Farm CO2 FREE maps nests and animals in regions of the Pantanal and the Atlantic Forest and, in addition, the project also has the role of educating the communities. About the preservation not only of the Harpy Eagles, but of all the fauna and flora of our forests.
