Best buddy’s in ring-tailed lemurs

Bachelor groups of ring-tailed lemurs are common in zoos, but not in the wild. That is why we have closely observed our ring-tailed lemurs for months. Result: They have their social preferences and form real bonds with their best buddy´s!

One claw less to feed

Male fiddler crabs can only eat with their little claw. They don't compensate for this by eating longer, and they just eat a little faster with their one claw. But they are more selective when it comes to feeding places!

The ape in the mirror

Few animal species recognize themselves in a mirror. Some great apes succeed in this, as decades old experiments show. But because these experiments were carried out in a way that no longer corresponds to today's scientific criteria, they were repeated. Only our chimpanzees, but not the gorillas, showed signs that they recognize themselves.

Paternity tests on rays

71 eagle rays have been born in Burgers' Ocean by now. We have developed a method to conduct paternity tests from the genetic material in their venomous sting. Knowing the parentage is important for the studbook of this endangered species.

Plankton fauna: Foraminifera

All kinds of micro-organisms live in the coral basin of the Burgers' Ocean. Water samples were examined by specialized scientists. They found 55 species of the unicellular, shell-bearing foraminifera. Their skeleton can be used to study climate change, which is why many scientific institutes now want our water samples!

How often does a shark eat?

In order to keep our sharks and rays healthy, records are kept of who eats how much. A great deal of knowledge has been assembled over time about the best diet for sharks and rays. The eagle rays now get food 12 times a week, the black-tipped reef sharks only 3 times.

Identify corals

A couple of aquariums and museums around the world are currently working together on compiling a large database of stony corals. Species determination in this group is rather difficult. So we collect DNA material and take macro photos of the living corals and their skeletons. We will soon know more about the species in our aquarium. The database will also be useful for protecting endangered corals in the wild.

Aardvarks at night

Aardvarks are nocturnal in the wild. So we wanted to know what our aardvarks are up to at night. Infrared cameras give a good picture of their circadian rhythm (the 24 hour rhythm). There are significant individual differences, but our aardvarks seem to be most active between 4 and 9 in the morning.

Counting butterflies

Tiny numbers were glued onto the wings of the blue morpho butterflies and a blob of nail polish was painted on as well. This enabled students to follow them through our Mangrove. We now know that the males fly around a lot more than the females. The blue morpho butterflies prefer some places in the Mangrove and avoid others.

The bear with the rubber duck

Do young sun bears know a transition point in their development at which they become suspicious of new stimuli? We received this research question from rehabilitation centres for these bears. We tested it by presenting tour bear cubs with a new smell, sound, or object three times a week. Result: they always remained open and curious!

Burgers´ Bush full of secrets

There are more animals, mushrooms and plants in our ecodisplays than we ever put into it! Our mini rainforest, for example, is a scientific paradise for experts in the field of for example woodlice, flatworms, freshwater snails and ants. Every year a couple research groups come to study the biodiversity in our Bush.

Welfare wise

The members of the Dutch zoo association NVD work together on a solid, scientifically correct and practical method to measure the welfare of zoo animals. This makes the data more valuable and usable. More than 80 questions about behavior, enclosures, food and health are asked for each individual. This year it's the turn of the big cats!

Aping chimpanzees

Researchers noticed that some of our female chimpanzees have developed their own tradition: they walk with their arm crossed in front of their chest. After two new females arrived, one of the two took over this quirk within a short time. This female integrated faster and developed more friendships. Coincidence?
