Singapore showed off two critically-endangered eagles Wednesday that were loaned from the Philippines as part of a breeding program to reverse the dwindling numbers of the feathered giants. 

A breeding program is also being carried out in the Philippines by a small band of conservationists at a sanctuary outside the southern city of Davao, close to the eagles' main forest habitat. 

Destruction of tropical rainforest and relentless hunting have decimated the population of the Philippine Eagle -- one of the world's biggest and most powerful birds whose wingspan can reach 2 meters — with only around 800 believed left in the wild.

The bird of prey, which has white and brown plumage and an enormous wingspan, is classified as "critically endangered" by protection group the International Union for Conservation of Nature. 

The Philippine Eagle is also the national bird of the Philippines, if you want to know more about other national birds of other countries around the world, CGTN Nature will tell you next time.
