Has Sandy the penguin finally found the one that she wants?

GERMANY - As it was for Sandy from the musical Grease, the road to love has been a rocky one for Münster Zoo's 14-year-old African penguin Sandy. Now zoo staff are hoping she has finally found her real Danny Zuko.

Her first crush was destined for failure when at a young age she fell for her human zookeeper Peter Vollbracht. Despite their species differences, she stayed faithful to him for 10 years, following him around and completely ignoring the zoo's other penguins.

"There was nothing we could do about it. I didn't choose her; she chose me," Vollbracht told Spiegel Online. "She didn't care about anyone else. I was just her big penguin."

But in 2006, Vollbracht got sick and had to stay away from work for six weeks, leading the lonely Sandy to move on to Tom, a much younger male penguin. In 2008, after a few unsuccessful mating seasons, they had two chicks together. Then, sadly, in 2009, Tom died of a bacterial infection. Sandy was unable to raise the chicks by herself so the zoo put them in foster nests.

After Tom died, widow Sandy returned to her first love, Vollbract. "I came back to work from vacation, and it was like she'd flipped a switch. She was looking for someone, and I was there," the zookeeper told Spiegel Online at the time. "It's nice for the zoo and to be followed around again, but I can't stay her partner forever. We can't find her a partner. She chooses, and it's her decision or nothing."

And now, it looks like she has made that decision, this time choosing sticking with her own species. Hermann is an older penguin who may bring some maturity to the relationship. Zoo staff are also hoping that Sandy won't get distracted by another younger penguin, and that Hermann will stay alive for a while longer yet.

"Up to now, she’s hasn’t really had that much luck with men," zoo spokesperson Ilone Zühlke told The Local.

She may have not had much luck, but at least she's hopelessly devoted to love.

Dog attacks on penguins "disappointing"

New Zealand - The Department of Conservation (DOC) has received two reports within a week of little penguins being attacked by dogs on Taranaki beaches.

"These attacks are really disappointing," DOC marine ranger Callum Lilley told Taranaki Daily News.

"They're so preventable. All people have to do is keep their dogs on a leash or at the very least watch and control them closely. If they chase seagulls they'll catch a penguin. They're easy game."

The latest penguin victim was taken to a local veterinarian where its wounds were cleaned and bandaged, and then transported to Massey University's wildlife centre to recover.

Researchers see the light about what makes little penguins blue

USA - Have you ever wondered what makes little penguins look blue? By examining the feathers of little penguins, researchers from the University of Akron, Ohio, and their colleagues have discovered a new way blue is created in feathers. Their finding is published in the 9 February issue of Biology Letters.

The researchers used light and electron microscopes to examine wing and back feathers of little penguins and found they contained massive numbers of fibres that were nanometres in diameter and arranged side-by-side. The neat, organised parallel alignment and tiny scale of the fibres cause light scattering in such a way that creates a blue hue.

While the light scattering of nanofibres is responsible for the blue colour of the skin of some birds and other animals such as mandrills, this is the first time is has been found as the source of the colour blue in feathers.

Dr Matthew Shawkey, one of the researchers, said, "For 30 years it has been thought that blue colours in feathers are only produced by cells of feather barbs in spongy layers, or matrices of keratin with nanometre-scaled pores in them. These results show that we should never stop looking just because we 'know' how something is made."

Portly penguins with "guilty conscience" avoid the scales

UK - I certainly avoid getting on the scales post-Christmas and New Year (especially this year after a week of American-style breakfasts in New York), and it seems the podgy Humboldt penguins at the National Seal Sanctuary in Gweek, Cornwall, feel the same way.

Since the six penguins arrived at the sanctuary last April they have been piling on the pounds, so the penguin team would like to record their weights and use this information to control their food intake. But even though the scales are camouflaged under the sandy floor of the birds' enclosure, it is proving difficult to trick the clever birds to get onto them.

Jenna Blacow, penguin expert at the sanctuary, said, "Penguins are sensitive birds and very skittish, so it would be far too stressful for them for us to chase them about and catch them by hand in order to weigh them."

"We have trained the seals to come out of the pool and sit on specially designed scales, and we are hoping we will be able to train our penguins to do the same, but so far it seems they have a guilty conscience about getting on the scales!"

"The penguins are smarter than we gave them credit for. They know we have hidden the scales and are stretching out their necks over them to grab the fish from our hands."

The penguin team will persevere, however, said Ms Blacow.

"Wild creatures are often wary when they are faced with something new, so if we keep trying hopefully we will succeed in getting them on the scales when they realise there is nothing to be afraid of."

In the meantime, the penguins will be hand fed and monitored carefully, and kept active with enrichment activities such as "penguin football".

Nothing says "I love you" like a penguin painting

USA - Described by Mystic Aquarium as "the ultimate tribute to Valentines Day", two pairs of the Connecticut aquarium's African penguins have created 50 original paintings. At US$124.99 each, a penguin painting could be just the Valentines gift you've been looking for that hard-to-buy-for special someone in your life. (Considering the price, perhaps a VERY special someone.)

The artists are Green-Blue and Green-Black, who have raised several chicks together, and Gray-Silver and Yellow-Red, who have been together for an enviable 17 years and appeared on both local and national TV.

Painting is a form of enrichment for the aquarium's penguins. A trainer dabs paint onto the penguin's feet and then sets the bird down on a canvas on the floor. The penguin wanders across the canvas and - voilà - a work of art! You can watch a video of a penguin painting here.

The original paintings, as well as reproduction posters and prints, are available from the Mystic Aquarium Online Store.  A portion from the proceeds of each sale will go towards the aquarium's penguin conservation efforts.

DOC relocates vulnerable Fiordland penguins

NEW ZEALAND - The Department of Conservation (DOC) has had to relocate two vulnerable Fiordland penguins recently.

One was found in New Plymouth on the North Island's west coast, quite far from the species' usual habitat along the southern coast of the South Island and Stewart Island.

Bryan Williams of DOC's marine team told the Taranaki Daily News, "It's only the second sighting [in the Taranaki region] in 20 years."

The poor penguin was looking a bit worse for wear after being battered by the rough weather so DOC took it into protective custody overnight. The next day the penguin was put on tug boat going south to be released in the ocean closer to home.

The other Fiordland penguin was found on a beach on the Otago coastline, south of Dunedin, where they are a much more common sighting. DOC biodiversity assets programme manager David Agnew told the Otago Daily Times that Fiordland penguins were the next most common penguins seen on Otago beaches after yellow-eyed and little penguins.

Since this penguin was just beginning its moult, it wouldn't be able to go back into the water for several weeks, and on this particular beach would have been at risk of dog attacks.

DOC moved the penguin to a safer place on Sandfly Bay on the Otago Peninsula, where it could moult in peace.

DOC praised the person who had notified them about the penguin's presence on the beach, and hoped that more people would act the same way if they saw vulnerable penguins during moulting season.

Canine graduates ready to protect penguins

AUSTRALIA - Congratulations to Eula and Tula, the latest Maremma sheepdogs to graduate from the training programme that teaches them to protect the little penguins on Middle Island from stray dogs and foxes.

The two-year-old sheepdogs will now spend up to four nights on the island, which is off the coast of Warrnambool, Victoria, without a handler.

The penguins' breeding season is from July to March so right now the sheepdogs' presence on the island is vital;  their scent deters foxes and other dogs.

Middle Island's Maremma patrol programme has been running since 2005, when there were only 10 penguins on the island. Now there are 180.

Coastcare facilitator Marty Gent told the Herald Sun "they've saved the colony".

Guarding animals is in the Maremmas' blood. In Italy, where they originate from, the dogs were used to protect sheep and goats from wolves and bears.
