Londoner Dani Connor traveled to Sweden last year and had the experience of a lifetime when she rescued four wild baby squirrels.

Dani Connor went from England to northern Sweden in March last year. She is a nature photographer as well as a zoologist and came to volunteer with another nature photographer. She fell for the Swedish nature and especially the wildlife very quickly, and especially for her new favorite animal – the squirrel.

With their exaggerated ears, charismatic personality and cute face, it’s hard not to fall for them, says Dani in one of her videos.

She remained in Sweden because of the corona crisis and spring came to Kalvträsk. Then a tragedy occurred – a female squirrel she had been following with her camera, which she called Remi, was run over. Dani knew Remi had kids.

– When I said goodbye to her, I sat in the forest for a while and suddenly I see something red in the grass. It was a small baby squirrel, she says.

She quickly realized that there were four cubs and that they would not survive without help. Dani then decided to save the cubs. From that day, she spent four to six hours in the woods with the cubs, making sure they were fed and comfortable.

She named them Little Pear, Baby Moomin, Cheburashka and Little Flame.

Pretty quickly the baby squirrels became comfortable with Dani and came down from the tree when she called. She developed a close relationship with them, something she says she learned a lot from.

– The squirrels have given me so much joy and also taught me patience and perseverance to keep them alive. They have also taught me the importance of creating bonds with individual wild animals.

 

The squirrels grew up and fended for themselves. It was therefore time for Dani to leave her squirrel family and travel on. Only at the end of 2020 did she come back to Kalvträsk again and look for her new family. Winter had come and the snow was thick on the trees. Every day she went to the forest where the squirrels had lived, without seeing any of them, but after a few days Dani finally caught sight of the squirrels. She put out some peanuts and several squirrels came to eat. However, it wasn’t one of the kids, but other squirrels.

Despite her daily visits to the squirrel forest, she saw no cubs, until one day when she stayed home. She looked out her window and saw a little squirrel sitting there.

– It wasn’t afraid when I opened the window and I immediately saw who it was. Baby Pear.

Shortly afterwards she also saw Cheburashka. Two of the baby squirrels had survived. She does not know what happened to the other two, but that two survived is still against all odds.

Dani concludes by saying that she had no idea that she would develop such a strong bond with these animals when she travelled to Sweden.

– After spending hundreds of hours in the forest, I learned to identify all the squirrels and their personalities. It was also fascinating to see the different bonds they had with each other.

Chimpanzees caught on camera sharing alcoholic fruit

Published 14 June 2025

For the first time, wild chimpanzees have been documented eating and sharing fruit containing alcohol. The research team speculates that this behavior could be described as an early evolutionary stage of “feasting”.

Researchers from the University of Exeter in England set up ten separate cameras with motion sensors in a national park in Guinea-Bissau in West Africa. There, they captured chimpanzees sharing the fermented fruit Treculia africana. The fruit contained an alcohol content of up to 0.61 percent. The behavior raises questions about whether and why chimpanzees consciously seek out alcohol.

– For humans, we know that drinking alcohol leads to a release of dopamine and endorphins, and resulting feelings of happiness and relaxation, said Anna Bowland, one of the researchers behind the study, in a press release, continuing:

We also know that sharing alcohol – including through traditions such as feasting – helps to form and strengthen social bonds. So – now we know that wild chimpanzees are eating and sharing ethanolic fruits – the question is: could they be getting similar benefits?

The amount observed is probably not enough to get the chimpanzees drunk, but the researchers estimate that the filmed episodes only provide a small glimpse into how much fermented fruit the animals eat in a day, as their diet consists of 60-85 percent fruit.

Researchers believe that more research is needed into why chimpanzees eat fermented fruit together, but speculate that the behavior may represent an early evolutionary stage of “feasting”.

Chimps don’t share food all the time, so this behaviour with fermented fruit might be important, says Dr. Kimberley Hockings of the University of Exeter. “If so, it suggests the human tradition of feasting may have its origins deep in our evolutionary history”.

Bats “surf” the winds to power their migration

Bats use the warm fronts of storms to “surf” as they migrate, research shows. This way, they use less energy and can fly longer distances.

The greater noctule bat is Sweden’s largest bat species, with a wingspan of 30 to 45 centimeters. The species also lives in Finland. Like birds, bats migrate thousands of kilometers annually across North America, Europe, and Africa. Now, researchers from the Max Planck Institute of Animal Behavior (MPI-AB) have studied 71 greater noctule bats during their approximately 1,600-kilometer-long spring migration across the European continent. Using sensors, the researchers were able to measure the bats’ activity levels as well as the air temperatures in which they were flying.

The researchers discovered that the bats often paused during their flights but could travel as far as 400 kilometers in a single night breaking the previous distance record for the species. The bats interrupted their migration flights with frequent stops, likely because they needed to feed continuously.

– Unlike migratory birds, bats don’t gain weight in preparation for migration, explains Dina Dechmann of MPI-AB, one of the authors of the study, in a press release. They need to refuel every night, so their migration has a hopping pattern rather than a straight shot.

Furthermore, an interesting pattern emerged in the bats’ migration. On some nights, more bats chose to fly than on others, which turned out to be weather-dependent. The bats began flying on nights when air pressure dropped and temperatures rose in other words, when storms were approaching. The sensors on the transmitters measuring activity levels also showed that the bats used less energy when flying on these warm, windy nights. After further analysis, it became clear that the bats were using the warm winds during storms to “surf”.

– They were riding storm fronts, using the support of warm tailwinds, says Edward Hurme, a researcher at MPI-AB. It was known that birds use wind support during migration, and now we see that bats do too.

The results of the study are important for the survival of bats, say researchers. Migrating bats are threatened by human activities, especially wind turbines which cause many collisions. Knowing where and when bats migrate can help prevent deaths.

– We can be stewards of bats, helping wind farms to turn off their turbines on nights when bats are streaming through, says Hurme.

Swedes earn money clearing invasive species

Large-leaved lupines are beautiful - but highly invasive.

Through a mobile game, individuals can “play” by heading out into nature, removing invasive plants, and even getting paid for their efforts. This year, seven Swedish municipalities are testing the game.

The Crowdsorsa mobile game has been used in Finland for three consecutive years, where last year it removed invasive plants from 7000 observations. It is also available in Canada.

This year, the municipalities of Hagfors, Örebro, Sunne, Karlsborg, Lilla Edet, Tanum and Falun are trying it out. The idea is that individuals find invasive plants, either via the map in the app or by themselves, remove them and get paid. As proof, they must film before and after clearing.

The total budget for this year in Sweden is SEK 126,000 (€11,600), which individuals can “play” for. At most, you can earn SEK 200 (€18.5) per hour, with the municipality responsible for paying out the reward.

“Fun way to work”

Last year, it was also successfully used in Hagfors and Örebro. In Hagfors, a total of 17 different teams played.

– The players did a great job! We think it’s a fun way to work with invasive alien species and an effective way to reach the public – and especially young people – with knowledge about invasive species, says municipal ecologist Katarina Karlsson in Hagfors municipality to Natursidan.

Invasive species often spread quickly and can displace native species, which in turn can damage the ecosystem. The game starts already in June, where, among other things, large-leaved lupine, Himalayan balsam and Canadian goldenrod will be removed.

Lion population growing in India

Asian lions have seen a strong resurgence in India in recent years. A new count shows that the population has increased by over 30 percent in just five years.

The number of Asian lions in the state of Gujarat in western India has risen from 674 individuals in 2020 to 891, according to the latest official count (May 10–13, 2025), reports The Independent. This represents an increase of 32 percent.

The lions live mainly in and around Gir National Park – the only area in the world where this subspecies of lion exists in the wild.

The new figure was recently announced by Gujarat Chief Minister Bhupendra Patel.

The number of lions in the state has gradually increased not just because of favorable geography and climate, but due to our government’s consistent and careful approach to wildlife conservation, said Patel.

Growing population

Over the past decade, the population has grown steadily, and lions have now spread to eleven districts in the Saurashtra region of Gujarat, where they can be observed in forests, grasslands, agricultural areas, and even coastal areas.

Of the 891 individuals, 196 are adult males, 330 are adult females, 140 are young adults (sub-adults), and 225 are cubs, according to state government figures.

Gujarat attributes the success to several efforts: regular monitoring, enhanced veterinary care, water and feed resources in the wild, and programs to reduce conflicts between humans and predators.

Drones, sensors, and camera traps are also used in an extensive monitoring network.

Vulnerability remains

Despite the increase, however, the lions remain vulnerable. The species is classified as vulnerable on the international red list, and threats include genetic inbreeding, diseases that can spread rapidly in the densely concentrated population, and fires and floods in the Gir Forest.

Sanjeev Kumar, Chief Secretary for Forest and Environment in Gujarat, explains.

The holding capacity of national park and sanctuaries will be increased by intervention and habitat improvement. There is still scope of increasing the holding capacity and the forest and environment department is working in that direction.

Gujarat has previously opposed proposals to transplant parts of the population to other parts of India, including the state of Madhya Pradesh, which has led to debate within the country’s environmental movement.

Asian lions (Panthera leo persica) are genetically and physically distinct from their African relatives. They are slightly smaller in size, have shorter manes in males, and live in smaller prides.

FACTS: Gir National Park

  • Location: Located in the state of Gujarat, western India
  • Established: 1965 (as a national park; the reserve was established earlier, in 1913)
  • Area: Approximately 1,412 square kilometers (including the national park and adjacent wildlife sanctuary)
  • Purpose: To preserve the last wild population of Asiatic lions (Panthera leo persica)
  • Ecosystem: Dry deciduous forest, savannah, and scrub forest with semi-desert elements
  • Animal species: In addition to Asiatic lions, there are leopards, spotted hyenas, Indian crocodiles (mugger crocodiles), axis deer (chital), sambar deer, and over 300 bird species
  • Threats: Forest fires, drought, genetic inbreeding, disease, and human impact such as habitat loss and conflicts with humans
