A frigatebird chick is being raised on Ascension Island for the first time in more than a century – and here it is, basking its downy feathers in the sun in this picture by Kenickie Simon Andrews.

Its arrival in the world came nine years after the island was declared free of feral cats, which had restricted most birds to breeding on tiny Boatswainbird Island.

A message on the Ascension Island Conservation page on Facebook says:

“At the end of last year, we observed the first two pairs of our endemic frigatebirds nesting on the mainland in over 100 years.

“Ascension was declared free from feral cats in 2004 and since then many of the masked and brown boobies have returned to the mainland to breed, but it was not until very recently that we observed the first of the returning frigatebirds.

“Unfortunately only one of the eggs hatched successfully, but as you can see the chick is doing very well.”

A thriving colony of masked boobies has changed the landscape on southern St Helena – by turning the ridges white around Lot’s Wife rock.

Annalea Beard, of the environment directorate, said: “Amazingly this species has re-established itself even though introduced predators such as feral cats and rats are also known to occupy the area.”

The colony was of global interest as a result, she said.

A few birds were observed nesting below Lot’s Wife, on the barren southern coast of the island, in 2009. A recent count showed 203 adults in the colony, which has turned the ridges white with guano.

“The reasons behind their re-colonisation and their ability to succeed remain
unclear,” said Annalea. “Monitoring is essential to make sure the colony continues to be successful.”
