In the modern age, many species of fauna and flora are threatened with extinction as natural habitats are destroyed.
But in Northern Ireland there is a tremendous environmental success story taking place with the reintroduction of the magnificent birds of prey, the red kites.
Four pairs of the birds have successfully bred five chicks, the first of the birds to be born here for more than 200 years. The hope now is that more breeding will take place and a viable population of the birds will develop.
The reintroduction of the birds has been a very carefully-managed programme involving environmentalists, public and private bodies, and farmers. All deserve our heartiest thanks for letting us glimpse a spectacle from the past.
