UK - It was hard to escape Royal Wedding fever in the UK, even for penguins.

Dudley Zoo in the West Midlands named two Humboldt penguins William and Kate when the wedding announcement was made, and zoo staff and hundreds of visitors helped the penguin pair celebrate the nuptials on 29 April along with the real royal couple.

As chicks, penguins William and Kate were rejected by their mothers during the cold snap last autumn. They were hand-reared by dedicated keepers and since November have made steady progress in the aviary nursery. They are gradually being introduced into the main group, which at 60-plus birds is the largest Humboldt penguin colony in the UK.

Dudley Zoo's CEO Peter Suddock explained that as the zoo incorporates the 11th century Dudley Castle, it has strong royal connections.

"Queen Elizabeths I and II have both visited and several dukes and earls have strong ties with the site, so we felt it fitting to send Prince William and Kate an adoption pack for their namesakes and wish them well for a long and very happy future."

"We’re not quite sure where [penguins William and Kate] will settle once they are fully integrated in the penguin enclosure, so just for fun we have labelled the nesting boxes Clarence House, Buckingham Palace, St James's Palace and Kensington Palace, to give them a fairly regal choice for their first home."

I wonder if penguins William and Kate now insist on being addressed as Duke and Duchess by the penguin commoners?

Manly's dog owners fight new bans

AUSTRALIA - Manly Council's new rules on walking dogs in Manly Cove have drawn heavy criticism from dog owners, who say the controversial decision was made without consultation and that their rights have been infringed.

The rules were introduced in March in an effort to provide better protection for the area's little penguins. The council had voted unanimously in December to enforce a "zero-tolerance approach" for any dog owners caught with their pets off-leash in on-leash areas, and for dogs to be banned from the steps up to Federation Point. It was also decided that other penguin protection measures, such as the installation of CCTV cameras, would be put in place.

Local dog owners say that they want the penguins protected as much as anyone, but that the council introduced the "draconian" rules without consultation.

Manly resident and dog owner Lloyd Keen told The Manly Daily that the group of dog owners was asking for the plans to be revoked until the wider community had the chance to comment.

"We understand the need to look after the penguins but no one’s really thought this through," he said.

"Most people with dogs do all the right things. Once Manly Council gets (the rules) right, then it needs to enforce them because at the moment it doesn’t."

The Manly Daily reported that the dog owners want leashed dogs to be allowed back on Federation Steps, and unleased dogs to be allowed on the Manly Scenic Walkway near Federation Point.

Manly Mayor Jean Hay has indicated that some of the dog bans may be overturned, telling The Manly Daily that leashed dogs should again be allowed onto Federation Steps. She said banning dogs from the steps "is taking away people’s rights".

"Let’s face it, the area belongs to everyone," she said.

No pity necessary for Mrs T

UNITED KINGDOM -  She may have lost an eye, but a macaroni penguin at Living Coasts in Devon is doing well.

Mrs T, described as a very laid-back penguin with good manners, was treated last September for a deep ulcer in the corner of her left eye. Unfortunately, the treatment did not work and she lost her sight in that eye. A specialist medical glue was used, but the eye became infected and animal experts decided that the best course of action would be to remove it.

"The eye became infected, the penguin was very subdued due to discomfort so we opted to remove the source of pain," zoo vet Sarah Chapman told the media.

The delicate eye operation was performed at South Devon Referrals by Veterinary Specialist Ophthalmologist Jim Carter and fellow vet Ian Sayers. 

Ms Chapman said, "Jim has the equipment and the experience for this intricate work. Having his specialist knowledge close to hand was invaluable."

The penguin recuperated at Paignton Zoo’s Vet Centre before returning to Living Coasts. Mrs T is very close to her mate, and when she returned "she ran out of her crate to be reunited with Mr T, which was very moving," said Living Coasts Director Elaine Hayes.

Ms Hayes continued, "She has had to learn how to swim and feed with just one eye, and to deal with the crowds of other penguins and the occasional spot of aggression that goes along with life in a busy penguin colony."

"We are confident that she will settle back in and hope she will breed."

Wash, rinse, dry and repeat for next penguin on Tristan da Cunha

TRISTAN DA CUNHA - The evening of Saturday 9 April provided a rewarding moment for Tristan's rehab manager Dereck Rogers as the first five northern rockhopper penguins to be washed at the newly erected wash-bay facility were drying off under infrared lights.

Mr Rogers, who has been closely involved with the care of the penguins from the moment the first oiled birds were brought back to Tristan more than two weeks ago, was elated at being able to hold a cleanly washed penguin.

The whole island worked together to ensure the expert staff from SANCCOB had everything they needed to erect the wash-bay facility, post-wash pens and pools. The island plumbers, electricians and carpenters were all on standby to assist with the operation, as well as plant operators for moving equipment and materials. The three large hot water geysers brought by the SANCCOB team have been installed in the wash-bay to heat the water for washing, as have hundreds of metres of piping and cable to link in to the island’s water and electrical supplies.

On Monday 11 April the washing of oiled penguins got well under way as the first islander washing team received training from SANCCOB's Venessa Strauss and Jennie Bancroft. Washing a penguin is a thirty-minute process involving a de-greaser mist, a warm bath of biodegradable soap and anti-septic solution, and a rinse with a high-pressure showerhead. The cleaned penguins are then tagged and put in a recovery pen under infrared lamps to keep them warm while they dry off. They are later moved to small clean pens which have access to a swimming pool, where there are encouraged to swim.

Sixty-four penguins were washed on Monday but SANCCOB’s vet, Tertius Gous, said they were aiming to wash up to a hundred a day once the washing team are in full swing.

Meanwhile, at the holding pens, the feeding teams are hard at work trying to satisfy the hunger of the many oiled penguins waiting to be washed. Penguins at the village swimming pool and in the outside pens are being fed pilchards to build up their strength before undergoing the washing process.

Some of the more lightly oiled penguins at the swimming pool are being "swum" every day, after which their waterproofing is tested. When these penguins satisfy the release criteria of effective waterproofing and sufficient weight, they will be released.

To date 3662 penguins have been admitted to the centre, of which 1577 have died. The first 69 to be washed will hopefully be able to join the 24 penguins released so far.

On Tuesday 12 April more help for the penguins arrived aboard the Russian research/Antarctic supply vessel Ivan Papanin - the fourth vessel chartered by the owners of the MS Oliva and their insurers since the incident. The Ivan Papanin carried the SANCCOB supplies and oil abatement equipment that were not able to be collected prior to the departure of the Svitzer Singapore. Aboard the Ivan Papanin is also a Bell-212 helicopter, which will greatly improve the deployment of the oil abatement teams and equipment into the oiled gulleys and bays on Alex (or Middle) Island, the focus of the clean-up efforts.

Currently there are 28 international responders on the island, including the SANCCOB team, veterinarians, International Tanker Owners Pollution Federation (ITOPF) staff, and oil pollution and salvage response experts. They are working alongside an 80-strong island volunteer force. 

The onset of the southern winter has brought with it gale force winds and rough seas. The adverse weather, while hampering the clean-up response, has broken up the majority of the released oil, although there are still clear signs of pollution around Nightingale. Fortunately the penguins have completed their moult, and the vast majority have left their colonies and gone to sea. They will not return to Tristan until the start of the next breeding season in August.

Great, mate! Eight little penguins successfully released into the wild

AUSTRALIA - Fit and healthy and ready to go - an unusually large batch of little penguins raced back into the ocean at Long Reef after a stay at Taronga Zoo's wildlife hospital in Sydney, NSW.

The eight penguins arrived at the hospital in recent weeks, some malnourished from their annual moult and some suffering injuries, including one which had to have a toe amputated after it became entangled in abandoned fishing line.

"It’s been a very busy season this year and we’ve seen a lot more birds than usual," said Libby Hall, Taronga Wildlife Hospital manager.

"We’re hoping it’s because there are more penguins out there this season, but we can’t be sure."

The zoo is caring for a further four birds, which are still not ready for release. Hospital staff had already rehabilitated three penguins which the NSW National Parks Service returned to the water at the Manly colony earlier this month.

"Most of these birds were brought to us by people who saw them in difficulties and took action. The community’s awareness of little penguins and other wildlife is increasing all the time and by acting, they give us the best chance to help the birds through difficult times," said Ms Hall.

"When they come to us, we can keep them safe and feed them so they can return to the ocean when they have finished moulting and weigh about one kilogram."

The birds were once fairly common in Sydney but urban development and domestic pets have placed them under pressure. The colony at Manly is the last remaining on the NSW mainland, with other colonies now located on islands which offer some protection from pressure from humans and domestic pets.

No "winning" penguin species when it comes to climate change

As global temperatures increase, ice-avoiding species like chinstrap penguins have often been considered one of the likely “winners” of changing conditions such as large-scale ice melting. A study published in the Proceedings of the National Academy of Sciences (PNAS), however, shows that the feisty Antarctic birds may actually end up as the most vulnerable to the impacts of climate change.

The research, which uses 30 years of field studies and recent surveys of chinstrap and ice-loving Adelie penguins, reveals that fluctuations in penguin populations in the Antarctic are linked more strongly to the availability of their primary food source - krill - than to changes in their habitats.

The populations of both Adelie and chinstrap penguins in the West Antarctic Peninsula and Scotia Sea have declined by respective averages of 2.9% and 4.3% per year for at least the last 10 years. Some colonies have decreased by more than 50%.

A previous assessment of krill in the Southern Ocean in Nature suggests that their abundance has declined as much as 80% since the 1970s.

“For penguins and other species, krill is the linchpin in the food web,” said Dr Wayne Trivelpiece, lead author and seabird researcher of the National Oceanic and Atmospheric Administration’s Antarctic Ecosystem Research Division.

“Regardless of their environmental preferences, we see a connection between climate change and penguin populations through the loss of habitat for their main food source. As warming continues, the loss of krill will have a profound effect throughout the Antarctic ecosystem.”

Lack of an abundant supply of krill has been particularly hard on fledgling penguins that must learn where to locate and how to catch the prey on their own, having never been at sea before. Data from the study suggest that fewer young penguins are surviving this transition to independence today than in previous years when these crustaceans were much more abundant.

Chinstrap penguins avoid feeding in icy habitats, but it is the sea ice that provides the necessary environment for krill to reproduce. Increasing temperatures and reductions in sea ice have made conditions unfavourable to sustain ample populations of this food source. The authors suggest that fishing for krill and increased competition among other predators also have made them less available to penguins.

Adélie penguins, which feed in icy habitats, are also declining due to food shortages and shrinking habitat. They differ from chinstrap penguins, however, in that they have breeding populations outside of the western Antarctic, which makes them comparatively less vulnerable to the rapid warming in the Antarctic Peninsula region.

“Penguins are excellent indicators of changes to the biological and environmental health of the broader ecosystem because they are easily accessible while breeding on land, yet they depend entirely on food resources from the sea,” said Dr Trivelpiece.

“In addition, unlike many other krill-eating top predators in the Antarctic, such as whales and fur seals, they were not hunted by humans. When we see steep declines in populations, as we have been documenting with both chinstrap and Adélie penguins, we know there’s a much larger ecological problem.”

Bonaparte's unrequited love for a Wellington

GERMANY - It seems that Bonaparte the penguin has met his Waterloo - a black-and-white Wellington boot.

Napoleon Bonaparte must be turning in his grave while his namesake, a gentoo penguin from Sea Life Centre in Constance, tries to seduce a rubber boot named after the French emperor's opponent the Duke of Wellington.

Bonaparte's keeper Dennis Kuebler told the German Herald, "He clearly sees sees the boots as a potential female mating partner. He rubs himself against them and gets very excited, showing off and trying to seduce the boot."

Mr Kuebler said that Bonaparte had even attacked another male penguin, Jasper, who got too close to his "rubber lover".

He added that next year the male and female penguins will be put together in the hope that they will breed.

"We will have to keep them away from my boot in the hope that they will turn their attention to the real females - not rubber ones."

The original Bonaparte - something of a romantic if his letters to his wife Joséphine are anything to go by - would approve.
