Penguin adoption – Promises

> The penguins have finally arrived back at the colony after their winter

> migration to Brazil. The weather is very mild for this time of year. Usually

> when the penguins arrive home in October it is still very cold, with snow on

> the hills. This year the snow disappeared weeks ago and it has been very

> pleasant working outside.

>

> This is the first time that the penguins have been ashore for months. During

> their winter migration the penguins stay out at sea all the time, eating and

> sleeping in the water. In the water the temperature barely changes from

> month to month. The ocean is so large that there are no sudden changes in

> the water temperature under normal circumstances.

>

> Antarctic currents running up the coast of Patagonia keep the seawater cool

> but stable. That current also brings nutrient rich water up the coast of

> Patagonia from Antarctica, which is why there are so many penguins and other

> marine species in this region, all feeding on the banquet of fish, krill and

> other marine life that the nutrient rich water supports.

>

> The Atlantic coast of South America does not suffer ocean current reversals

> such as those that occasionally occur along the Pacific coast during El Niño

> and La Niña years. However, El Niño and La Niña cause such severe climatic

> changes that they affect the entire southern half of the South American

> continent, bringing strange weather patterns across the region that do

> affect our penguins.

>

> Some scientists are predicting another La Niña year this coming season, and

> the warmer weather that we are experiencing at the moment is consistent with

> that, but it is still too early to tell for sure.

>

> The first thing that the penguins do after returning to the colony is

> reunite with their partners. The pairs are forced to separate during the

> migration because it is impossible for penguins to maintain visual contact

> with each other out at sea. The penguins keep together in large groups, but

> constant diving for fish makes it impossible for them to keep track of

> individual penguins. Remaining together as a pair for weeks would be

> impossible so they don’t even try. The pairs just reunite back home at the

> nest in October.

>

> Penguins recognize each other on land by their calls, which is something we

> are unable to do. With 300,000 penguins in the colony, we are not able to

> identifying individual penguins amongst all the other penguins until they

> have returned to their nest. Once they have settled into their nest and

> begun laying eggs, we can then be sure of their identity and begin taking

> photos.

>

> Magellanic penguins are territorial about their home just like humans.

> Penguins consider their bush to be their home and return to the same bush

> each year. If a penguin is late returning to the colony, then another

> penguin might decide to make use of the bush, but since only young penguins

> breeding for the first time would be looking for new bushes, these

> inexperienced birds are quickly evicted when the genuine owner of the bush

> returns.

>

> Small bushes are like houses with one nest per bush. Larger bushes are more

> like apartment blocks with several penguins each occupying their ‘apartment’

> within the bush. There are also semi-detached bushes with a medium sized

> bush being home to two nests.

>

> Each year the penguins like to move their nest to a clean spot that was not

> used the year before, limited of course by the size of their bush. Fleas lay

> eggs that over-winter in the soil below the old nest, so moving the nest

> even just half a meter can reduce the burden of fleas. One or two meters is

> better if the space around the bush allows.

>

> Magellanic penguins always lay two eggs, which then need to be kept warm for

> six to seven weeks in order to hatch. It would be impossible for one penguin

> to keep the eggs warm for that long on their own. They would not be able to

> go to sea to eat any fish if they had to keep the eggs warm on their own.

> That is why penguins work together as a couple.

>

> One penguin stays in the nest lying over the eggs to keep them warm, whilst

> the other goes to sea to catch food. Then they change over every two or

> three days so that both can spend time at sea catching food. If it goes

> beyond a week the partner left in the nest with the eggs is forced by hunger

> to abandon the nest and go to sea. If that happens the exposed eggs get cold

> and are quickly stolen by gulls, foxes or armadillos.

>

> That is quite common amongst young couples breeding for the first time, who

> are less familiar with where to find local fish shoals and easily become

> delayed finding food. That is the main cause of egg loss amongst young

> couples, and accounts for many of the egg losses in the colony as a whole.

> Experienced couples are more familiar with the area and rarely have problems

> finding sufficient food to feed themselves at this time of year. Nest

> abandonment by experienced couples is rare.

>

> This year is a very difficult year for us working with the penguins.

> Financial hardship around the world caused by lock-downs and loss of

> employment has caused a huge drop in new adoptions, so our revenue has been

> severely reduced. We also now have problems moving around due to the

> coronavirus restrictions imposed here. You may have heard on the news how

> Brazil, Chile and Argentina have all been very badly hit by COVID-19.

> Lock-downs and night-time curfews have been in place here since March.

>

> The penguin colony here is usually open to the public, but it has been

> closed since last March. The park wardens that usually work here to show

> tourists around have not worked here since March, and of course there are no

> tourists either. The colony is completely deserted except for the penguins,

> myself and one assistant.

>

> Not only do Chile and Argentina both have their borders closed to other

> countries, but they have also created internal ‘sanitary borders’ to prevent

> travel from town to town within the country. People that worked with us last

> season left the area to visit their families whilst the penguins were away

> in Brazil, and are now unable to return because of the regional travel bans.

> Nobody expected the lock-down in this region to last for seven months.

> We also have two other study colonies in Chile, both on islands in the

> Island. These colonies are 40km and 60km away from Punta Arenas. Getting to

> As is the case in many remote coastal communities, the long brown seaweed

> Crossing on these boats brings back old memories, because when I first began

> incubation and hatching of the penguins. So in those early years all my
