It is the first time the global population of any species has been assessed from orbit

Scientists have started counting individual Northern Royal albatrosses from space.

Using the highest-resolution satellite images available, scientists from Britain and New Zealand are calculating the number of endangered albatrosses living on New Zealand's remote and inaccessible Chatham Islands.

It is the first time the global population of any species on earth has been assessed from orbit.

The study, published in the journal Ibis, used the DigitalGlobe WorldView-3 satellite, which can observe objects as small as 30cm across.

The endangered Northern Royals could be seen as they sit on eggs to incubate them, or when they guard newly hatched eggs, allowing the researchers to count them.

The study found the number of Northern Royals is stable on one inaccessible island, but has declined dramatically on another island group.

“This is a major conservation concern for this globally-endangered albatross species,” said Professor Paul Scofield, Canterbury Museum’s Senior Curator Natural History and a co-author of the study.

“This technique will be an invaluable global conservation resource that can give us near real time information about the status of endangered species.

He added: “The ground-breaking image resolution of the newly-available satellite will provide a step change in our ability to count albatross, large birds and other wildlife directly from space without disturbance, at potentially lower cost and with minimal logistical effort.”
