Region – Births for spring: 7 penguins and 2 small tamarins


Since the beginning of the year, Amnéville Zoo has welcomed many births of impressive species such as white rhinos and a small orangutan. To mark spring, these are the births of smaller species, but so important for the preservation of biodiversity with the birth of 2 small pinched tamarins and 7 baby penguins.

Families grow in the Bay of Peruvia

The colony of 26 penguins was delighted to welcome 7 babies from mid-April to early May, including 2 siblings. In addition to being a generally faithful couple if reproduction works, it is as a team that they will take care of the babies with a relay that will take place between the father and the mother. The female lays eggs in pairs with an incubation period of 40 days. Babies stay with their parents for 2 months as they cannot swim or feed on their own. It is then with the regurgitation of the parents that they will initially feed. At the end of these 2 months, they will start to leave the nest and eat the fish on their own. To enter the water, you will have to wait for them to change to move from their plumage to their first plumage. This transformation will allow them to swim.

A participatory family

It is in the space of the Amazon Jungle that the most attentive visitors will be able to discover the 2 new crested tamarins still pressed against their mother. They weigh between 30 and 40 g at birth and will gain about 10 g per week. This is the 3rd litter of this couple, Guinness and O’Hara who had already welcomed 2 tamarins at the beginning of 2021. Babies that have grown well because they are now helping the parents carry the new little ones. For these little monkeys, gestation lasts 4 and a half months. They form a monogamous couple and live in a small family group where everyone participates in raising the young.

Conservation in the Zoological Park

While it is quite complex today to determine their exact number, the wild population of Humboldt penguins is estimated to comprise around 23,800 mature individuals.

Classified as “vulnerable” by the International Union for Conservation of Nature (IUCN), this subspecies of penguin is seeing its population decrease due to anthropogenic pressures, namely due to the exploitation of guano, its droppings, which prove to be a fabulous fertilizer. . In fact, it is an essential nesting material for penguins. They use it to shape and dig their nests. Without this precious guano, they nest in other substrates such as sand or rocks, which exposes them to much more weather and predators. Overfishing will also have a severe impact on the life cycle of these animals.

In fact, the fragile balance that involves its reproduction depends on the availability of resources contained in the very rich Humboldt Current. Wealth that naturally attracts those involved in overfishing and intensive fishing, greatly reducing wild fish stocks

As for our little primates, they are classified as “critically endangered” by the IUCN. These small primates, present today only in 5 departments in northern Colombia, are seriously threatened by the loss of their habitat and the capture of live individuals destined for pet trafficking. The loss of suitable forests for the presence of these monkeys has dramatically intensified in the last 3 years, seriously compromising the future of the species. The capture of live animals is difficult to quantify, but the increasingly frequent seizures of these animals reflect a worrying observation.

EEPs (EAZA ex situ program) are breeding programs applied to the most threatened species. The Humboldt penguin and the black-crested tamarin are among them. These programs managed by zoological parks make it possible to perpetuate, outside the natural environment and therefore away from these pressures, stable and genetically viable populations, thus guaranteeing a future for these species.
