This 2017 video from South Africa says about itself:
Boulders beach, at the southern most tip of the African continent is home to a variety of wildlife and endemic birds.
It is also home to a rare and loveable character, the African penguin.
Penguins live on a range of 24 islands from Namibia to Port Elizabeth in the Eastern Cape.
The Boulders beach colony in Simonstown is the largest land-based colony and one of the only places that people can get up close to observe these adorable creatures.

No-fishing zones help endangered penguins
January 16, 2018
Working with the South African government, researchers from the universities of Exeter and Cape Town tested bans on catching “forage fish” such as sardines and anchovies — key prey for the endangered penguins — from 20km around their breeding islands.
The body condition and survival of chicks improved when the no-fishing zones were in place.
More research is needed, but the scientists say the fishing closures should continue in South Africa and should be considered elsewhere.
“The amount of forage fish caught worldwide is increasing and — although the effects are disputed — the impact on marine ecosystems could be severe”, said Dr Richard Sherley, of the Environment and Sustainability Institute on the University of Exeter’s Penryn Campus in Cornwall.
“We need to do more to understand the circumstances in which small no-fishing zones will improve the food available to predators, but our research shows this is a promising way to help African penguins.”
The test areas were on a small scale compared to some no-fishing zones worldwide, which can cover hundreds of thousands of square kilometres.
The study says evidence for overall effects was “subtle and inconsistent”, with clear benefits for penguin populations at only two of the four islands.
Dr Sherley said it was difficult to discover the full effects of the no-fishing zones because many other factors also affect the birds.
“Decades of research may be needed to be absolutely certain of the impact on the penguins’ population size,” he said.
However, the researchers used a statistical method called Bayesian inference to demonstrate beyond doubt that the zones improved the health and survival rates of penguin chicks.
“There’s never going to be a quick answer to problems in complex ecosystems”, Dr Sherley said.
“However, without conservation action, there’s a good chance African penguins will go extinct in at least some of their current colonies.
“We are calling for a precautionary and adaptive approach — no-fishing zones to protect this species, with an open mind to change as more evidence emerges.”
Dr Stephen Votier, senior author of the study, added: “This is an excellent example of how a collaboration between government, fisheries and scientists can lead to positive outcomes for conservation.
“Statistics have played an important role here — only by using the approach we adopted was it possible to understand fully that these fisheries closures do indeed work.”
The paper, published in the journal Proceedings of the Royal Society B, is entitled: “Bayesian inference reveals positive but subtle effects of experimental fishery closures on marine predator demographics.”
World governments and other leadership bodies are taking vital steps to protect the ocean but more progress is urgently needed, Oregon State University scientists reported today at the Our Ocean Conference: here.
