Penguin adoption - Promises

>
> Dear PenguinPromises
>
> The penguins have reached the coast of Brazil and will be having a great time.
> The sky is blue, the sun is shining, and the water is crystal clear. Catching
> fish is easy for Promises with such good sunshine and clear water.
>
> When Promises is home in the colony raising chicks, just one type of fish makes
> up 90% of the diet. The common name for those fish is Sprats, and the scientific
> name is "Sprattus fuegensis". The reason that the penguins almost exclusively
> catch sprats here in the south is because they are very common in Patagonia,
> and live in large groups, called shoals.
>
> Because sprats live in shoals, the penguins are able to catch them quickly once
> they have located the shoal. The penguins swim around the shoal eating one fish
> after another, and can quickly catch enough to take back to the nest. Of course
> the shoals have millions of fish, and the penguins only eat a tiny fraction,
> otherwise living in shoals would make no sense for the fish.
>
> By contrast, fish that don't live in shoals would take ages to catch in the open
> ocean. The penguins would have to look for them one fish at a time, which would
> take too long when there are hungry chicks back home waiting to be fed.
>
> In Brazil there are different types of fish to eat. Penguins are not picky about
> their food, and Promises will eat almost any fish that is small enough to be
> swallowed whole. Penguins do not have teeth, so they cannot chew their food.
> They must swallow the fish whole, and that means that the fish have to be the
> right size. For Promises, the size of the fish is more important than what species
> of fish it is.
>
> In Brazil the penguins eat many kinds of fish that are not found in Patagonia,
> including solitary fish that do not live in shoals. The penguins now live in
> the water all the time, so they do not have to waste time traveling to and from
> a nest each day to find the fish. They also have no chicks to feed and only need
> to catch enough food to feed themselves, so there is no rush. At this time of
> year Promises can easily catch enough food feeding on solitary fish that are
> not in shoals.
>
> The penguins are now spread out from southern Brazil to north of Rio de Janeiro.
> The Rio Times, which is the local newspaper in Rio de Janeiro, published an article
> saying that the "2021 Penguin Season" has begun. The article talks about the
> penguins arriving in the area on their winter migration.
>
> Penguins have no need to come ashore at this time of year. They have everything
> they need out at sea. Most people living in Brazil have never seen a penguin
> because the penguins stay away from the coast in open water. If the newspaper
> had not written the article, many people in Rio de Janeiro would be unaware that
> there are so many penguins just a short distance off the coast.
>
> If you wish to read the article you can find it at:
> https://riotimesonline.com/brazil-news/nosubscription/2021-penguin-season-begins-on-brazils-southern-and-southeastern-coasts/
>
> However the article is very misleading, talking about poor hungry penguins moving
> into an area where it is difficult to find enough food. That is simply untrue.
> Whilst it is true that the waters around Brazil are not as rich in fish as Patagonia,
> the penguins' needs are also very different at this time of year as I mentioned
> above. With no chicks to feed, the penguins only need a few fish a day to be
> well fed.
>
> It is little use spending the winter in the south where there are more fish,
> when the days there are too short and gloomy for Promises to be able to see the
> fish deep underwater. That is why the penguins migrate to Brazil each year.
>
> The penguins swim a long way to leave the rich waters of Patagonia and spend
> the winter off the coast of Brazil. They would not do that if Brazil was unsuitable
> for their needs. The writer of the Rio Times article has assumed that all the
> penguins in Brazil are in the same condition as those that get washed ashore,
> which is not the case. To be fair it is just a newspaper, and does not pretend
> to be a scientific journal.
>
> With over four million penguins along the Brazilian coastline, it is not surprising
> that some penguins will get sick and die, but very few of those are adult penguins.
> The adult penguins find food easily in Brazil and do not loose weight. On the
> contrary, the adults have a very restful time in Brazil and return home fatter
> and healthier than at any other time of year.
>
> The penguins that the article refers to are eight month old juvenile penguins
> that were born last year. These penguins are not underweight because of a lack
> of food in the area. These young juveniles are under-weight because they still
> lack the strength and speed of the adults, and are not fast enough to catch fish
> easily. The first year is always tough for these juveniles. Most survive their
> first year and go on to become strong and healthy, but sadly some do not make
> it and get washed up ashore.
>
> In Brazil there are beach patrols that look for sick and under-weight penguins.
> They help these penguins by giving them food and letting them rest for a couple
> of weeks in their penguin hospital, before releasing them back into the sea.
> I attach a photo of one of these people helping a juvenile penguin. The lady
> in the photo is part of the Santos Basin Beach Monitoring Project.
>
> The penguin in the photo is an 8 month old Magellanic penguin, and is healthy
> except for being underweight. After a week or two in hospital with plenty of
> fish, he will be released back to sea. The photo is part of the Rio Times article
> which also promotes the valuable work being done by the Santos Basin Project.
>
> The penguins will remain in Brazil for a few more weeks, and then Promises will
> start heading back home. Back here in the empty colony the days are starting
> to get longer again, so spring is on the way. Before long it will be time for
> Promises to begin another season of chick-rearing.
>
> I will write to you again in a few weeks, by which time Promises will be heading

What is success?

Success is not giving a hoot.  If you can be a 45 year old cat woman playing in front of 3000 people, totally uninhibited, then you are succeeding.  Because if you are able to do that, you are in the present moment, not caring about what anybody else thinks.  Not worried about their judgements or how you think you should be coming across.  (ok, so I was a little worried, so not 100% successful, but I continue to strive to be free of this nonsence) When you have that presence of mind in front of animals, that is when you are succeeding. 

Overwhelmed

Sometimes I spend time with people who see others in a different way to me. I am left feeling insecure in my intuition. Some believe that human beings are inherently bad. I prefer to see them as inherently good. With regard to people in relationship with animals, any poor relations, I see as misunderstandings or confused belief systems. I need to be able to trust my take on people. Because if I don't, there is no hope. If we don't inherently care, if we don't have that foundation to which we can return once we put our ego and greed aside, then there is no hope. People governed by their egos do three things when faced by challenges - 1. Keep doing the sam and expect a different result. 2. Dig in their heels and force the issue. 3. Give up and walk away with an excuse. All points refuse to acknowledge a problem which can be solved because it is a problem of our own making. So, when I look around and see litter, pollution, unethical care of humans and animals, corrupti...

A Lesson in Surrender

  I always found the concept of surrender a cop out.  Something one would do if one was too weak to take on a situation.   So, when I found myself in a situation where I am unable to follow my passion in the most effective manner, I experienced great discomfort.  Speaking up was immediately taken as judgement.  Even though it was never intended as that.  The presumed judgement resulted in defence.  And the drama began, and unfolded.   Chasms and vindication ruled.  Frustration and finger pointing. What has this to do with animals?   For those of us that work with animals, they are like kids.  They sense how we feel.  Our moods affect them.  So, when this type of angst environment is created, the disturbance affects the creatures that we love. The lesson – stop the angst.  It is not worth upsetting the animals.  Nothing is.  So, surrender.  Not sure where this will go.  But I am here righ...
