Happy feat: penguins swim fifteen thousand kilometres in six months

Call it a happy feat.

New Zealand scientists have been astounded to find that two species of subantarctuic penguin were able to travel 15,000km - equivalent to the distance between Auckland and Boston - over a stretch of just six months.

The insight was revealed by a tagging project observing nearly 100 subantarctic rockhopper and Snares penguins over winter in the Southern Ocean.

"If they are constantly moving this averages out at about 100km a day but you also have to add on to that the distances covered vertically as the birds dive to capture food," said the study's leader, National Institute of Water and Atmosphere seabird ecologist Dr David Thompson.

While the Snares penguin population on their craggy namesake islands was relatively stable, Campbell Island's rockhoppers had dwindled by at least 21 per cent since 1984, leaving just over 33,000 breeding pairs there.

Very interesting. The study of penguins could take up a lifetime of work.

“Happy feat.”

That’s a cute and clever grab-line. I understand having to work around the “ spoonful of sugar” demographic but wow-

“Between 1942 & 1984 the population dropped by about 94%.”

-is a tragic mouthful to swallow.

"We think winter is pretty important and that there is almost certainly something going on in the ocean causing the population to decline."

Sweetly worded little sentence, right there.
