I recently illustrated a memo game "Endangered Animal Babies" for Treecer. This memo game contains 72 unique illustrations and 36 endangered animal species. Each pair consists of the parent and the baby animal and all the illustrations were done in watercolor.
I'm really grateful for this opportunity and very happy with the outcome of the game! The game is sold by WWF Finland and Treecer at the moment.

The young penguins of South Africa shed their down, preparing for the struggle to come. Since their habitat was destroyed by mining, eggs are laid on sand instead of burrows, and the exposure to the elements kills many eggs before they hatch. Parents are forced to venture many more kilometers out to sea to find fish, as trawlers empty the ocean for distant tables. Regulations limiting fish harvests is desperately needed, not only for sea birds but for people who traditionally make their living fishing off the coast. In international waters, trawlers have total freedom, which can collapse fisheries. Alternatively, reducing ocean fish in your diet can counter this problem.
AFRICAN PENGUINS IDENTIFY PATNERS BY THEIR CHEST DOTS
Birds are known to be highly social and visual animals, and penguins are not the exception, as they live in dense colonies. Yet no specific visual feature has been identified to be responsible for individual recognition in birds. Now, researchers demonstrate that african penguins (Spheniscus demersus) can recognize their each others using their ventral dot patterns.
Researchers placed a experiment at the Zoomarine Marine Park, in Rome, Italy, to test how penguins will react to a model with plain with no dot penguin, and to penguins with dots, to find out penguins actually could visually recognize the dots of their lovers and friends in the zoo.
Penguins rely strongly on their ventral dot patterns for individual recognition, and may have holistic representations of other penguins in the colony. In this video below, an african penguin named Gerry appears to recognize his mate, Fiorella (left), in an individual recognition experiment.
These findings suggest that african penguins may rely on a more holistic visual representation of their partner, which includes both the ventral dot patterns and their partner's facial features. Notably, these abilities are not dependent on the ability of a pair to produce offspring together. Nemo and Chicco, male partners, showed the same preference for each other as other penguin partner pairs, suggesting that the ability to distinguish the partner from others is driven simply by the special bond developed between nesting partners.

African Penguins (Spheniscus demersus), also known as jackass penguins, are small penguins found along the coasts of southern Africa. You can read more about the penguins, threats to the species, and conservation efforts at their IUCN Red List page and the Global Penguin Society.
The African penguin was once abundant in South Africa and Namibia, but oil spills, egg harvesting, the collection of guano for fertilizer, and overfishing reduced their wild population to less than 50,000 individuals. Because they don't require a frigid environment, there are efforts in multiple countries to breed them in captivity.
We’re sad to share that recently hatched African penguin chick, Pfeiffer, has a congenital heart defect that can’t be repaired. Veterinary medical experts at UC Davis found a hole in Pfeiffer’s heart when our Veterinary team – who had been closely monitoring the chick and were concerned about Pfeiffer’s overall health – sent the bird there for an in-depth exam. We always hope that every animal at the Aquarium will live a long and healthy life. For animals like Pfeiffer that face challenges, we ensure that their lives – however long – are the best they can be.
Because penguins are social birds that do best in the company of others of their species, you’ll see Pfeiffer splish-splashing with the rest of the colony in our penguin exhibit. Aviculturist Dominique Blair says that Pfeiffer seems to really enjoy the water and spends a lot of time there. Right now the young bird is wearing a wing band that’s black with white letters, which usually identifies females, though we don’t yet know their sex. A strong-willed and independent juvenile penguin, Pfeiffer lets our aviculturists know that they are big enough to take care of themselves! Dominique observes, “Pfeiffer often gives me a very obvious side-eye judgment when I'm doing silly human things like singing/dancing during cleaning or trying to play with their enrichment items.”
Because of Pfeiffer’s heart condition, our aviculture and veterinary teams will be extra attentive to the bird’s overall health. They’ll be watching for subtle signs that something is amiss so they can intervene with treatment to help Pfeiffer remain active and comfortable for as long as possible. That’s our number one priority for every animal under our care.
Meet December's Pal of the Month: African Penguins!
African penguins, also known as black-footed penguins, are one of only four penguin species found in warm climates. They are distinguished by the bare pink skin above their eyes, which help them regulate body temperatures in the warmer south African temperatures. When they overheat, blood flow to this area increases, cooling blood before it circulates back through the body. The hotter it is, the pinker these patches become!
African Penguins communicate using three distinct calls: a bray, a yell, and a haw. Each individual has unique vocalizations that help them recognize each other. They are swift swimmers, reaching speeds of up to 12 mph and can hold their breath for up to 2 minutes.
Despite being a popular zoo penguin, there are fewer than 165,000 African penguins left in the world according to the International Union for Conservation of Nature (IUCN). Donating to your local zoos helps them collaborate with conservation partners to help rescue, rehabilitate, and release penguins.
This month, Pen Pals will receive a 3in African Penguin sticker! Thanks so much for being here everyone and being you! I hope you enjoy your sticker this month!
