I originally ordered this stamp to use it as an illustration in the book The Red-haired Librarian. But it only just arrived from England and the book has been on sale for several weeks.

Kawi celebrated his second birthday recently. The male Sumatran orangutan is learning veterinary training, eating more and more solid food and his acrobatic stunts make him a favourite with zoo visitors. But above all, his rare genes mean he is a hope for the conservation of his species.

On Monday in the early evening, I popped in to the Dja Reserve again. Three gorillas were sitting side by side under the window to the enclosure: Kisumu, the male that we had brought from Austria two months ago, Moja’s daughter Duni, who had arrived from Spain a week after Kisumu, and Shinda, one of the three females from our...

Yesterday a big gorilla meeting took place at Prague Zoo without too much fuss. Newcomers Kisumu and Duni met the rest of the group - females Kijivu, Shinda, Kamba and Ajabu, a small male. After Monday’s minor quarrels, the situation is much calmer now. Visitors can observe the six freshly integrated gorillas in the Dja Reserve pavilion.

As of today, approximately one hundred small crucian carp bred at Prague Zoo have been inhabiting the U Kamenného stolu pond in Prague’s Vinoř district. They were released by the staff of Prague Zoo, thus starting the long-planned reintroduction of this almost extinct species into the Czech countryside.

Fur seals are Carnivorans and skilled aquatic hunters. Their diet consists mainly of fish and squid, but they can even take on a small shark. However, they must stay alert themselves.

A female fur seal gives birth after a nearly year-long pregnancy, typically to a single pup, from which she doesn’t stray at all during the first few days. Since the pup initially cannot swim, lacks blubber, and its fur is not waterproof, it would quickly get cold in the water, so the mother stays on land with her offspring and fasts.

On land, fur seals gather into colonies, which consist of harems—groups made up of an adult male, up to fifty females, and pups conceived the previous year. Males are easy to distinguish from females: they are significantly larger and have a noticeably thicker neck.

Fur seals forage in the ocean, but they breed exclusively on land. They can spend up to half a year on beaches or rocky islets. This is not only the time of births and raising pups but also mating. Fur seals enjoy basking in the sun and resting on the shore.
