This protected natural paradise is a hotspot of biodiversity<\/a>, containing a mosaic of different habitats<\/a> including rainforest, wetlands, lagoons, savannahs, coastal rainforest, floodplains and mangrove forest. The park covers about 1,500km^{2<\/sup> and is managed by} Gabon\u2019s National Agency for National Parks (ANPN).<\/a><\/p>

The Rekambo chimpanzee community (rekambo<\/em> means “where English is spoken” in the local language) consists of about 40 individuals. The Ozouga Chimpanzee Project team, led by Tobias Deschner and Simone Pika, head of the comparative biocognition research group at Osnabr\u00fcck University\u2019s Institute of Cognitive Science, has documented previously unknown *chimpanzee<\/a> behaviour in Gabon\u2019s Loango National Park.<\/p>*

It took the Ozouga Chimpanzee Project team more than 10 years to habituate this community and be able to observe their behaviour up close. The research project started in 2005.<\/p>

In six years of collecting detailed data on the Rekambo chimpanzee community, the Ozouga Chimpanzee Project team has documented some startling behaviours, such as chimps attacking lowland gorillas<\/a>, and even killing and eating one. They have also observed the use of tools, with chimpanzees using different-sized branches to dig out honey from underground beehives and crack open tortoise shells.<\/p>

The Loango chimps\u2019 extraordinarily large territories mean that encounters with large mammals such as forest buffalo or forest elephants<\/a> are not uncommon. Researchers are studying how the chimps and other species compete for food.<\/p>

Alessandra Mascaro, an evolutionary biologist at Osnabr\u00fcck University<\/a>, first saw individuals within the Rekambo community treating their injuries with insects in 2019. Her PhD project now focuses on wound care and the substances used. One aim of her study is to find and identify the insect species the chimps catch to treat their wounds. In this photo, she searches the forest floor where Thea was sitting *(see below)<\/em> to find the insect that he applied to his wounds.<\/p>*

Thea, a male of the Rekambo chimpanzee community, suffered several injuries during a violent conflict within the group. The clash was a result of male chimps competing over females.\u00a0<\/p>

Thea immobilises an insect between his lips and crushes it. He then takes the insect out of his mouth and carefully applies it to an open wound on his left thigh, sustained during a fight with other males in the group. Thea repeats the procedure several times before finally cleaning the wound with his fingers.<\/p>
$\"Chimps$

Grooming is an important way to establish and strengthen friendships among primates. The treating of wounds may have a similar function and suggests that chimpanzees understand and care about the wellbeing of others. This possible prosocial behaviour is interesting for cognitive scientists because prosocial behaviours have been linked with high cognitive skills.<\/p>

Oestrus is the most fertile phase of female chimpanzees\u2019 reproductive cycles. They signal their receptivity with a shiny, reddish swelling of the genital region. These sexual swellings increase gradually in size throughout the female\u2019s cycle and are very attractive for male chimps.<\/p>

Thea shows his razor-sharp canines to rival males. To maximise their chances of reproductive success, males try to monopolise females in oestrus within their group. The competition can lead to severe aggression, often resulting in injuries among the males.<\/p>

Male chimpanzee Littlegrey enjoys a dip in a small river to escape the midday heat. Littlegrey is a special character because he loves bathing and being in the water. In contrast, most other Rekambo group members try to avoid getting wet, and cross rivers either on logs or on two legs.<\/p>
