International Census of the Great Green Macaw

International Census of the Great Green Macaw

Critically endangered parrot species

Yesterday the research program of Adopt Rainforest participated in the Censo Internacional de la Guacamaya Verde 2022. Or in English the International Sensus of the Great Green Macaw. Throughout its distribution, dozens of organisations participate in the next days to get an understanding of the current state of this parrot species. The entire world population of Great Green Macaw was estimated around only 500-1000 individuals in 2020. It is considered a Critically Endangered species bij de IUCN. Most of these spectacular birds live in Costa Rica.

Countings in the reserve

Yesterday from 16:00-18:00 and today from 05:00-07:00 we contributed by doing a count in the most upper parts of the reserve, close to National Park Barbilla. Yesterday we heard two individuals just before the night turned pitch black, right in our own reserve. This morning, we managed to hear them again far away around the park borders. Together with all the other organizations, we hope to provide detailed numbers to assess the population sizes.

A better future for the Great Green Macaw

Luckily, numbers seem to be growing in Costa Rica. The species mainly breeds in the North of the country and we only get to enjoy them after breeding, when they disperse into the foothills of the Talamanca mountains. But as their number grow, we hope to some day welcome breeding pairs in or around the reserve. Plans are made to hang artificial nests in order to entice the visiting individuals to stay for breeding season. We have also planted hundreds of wild Almond trees, their primary food source. Let’s hope the efforts will pay off!

Adopt some rainforest!

Morpho butterfly in Costa Rica

This beautiful blue butterfly, measuring up to 15-20 cm, seems to appear and disappear with every flick of its wings. In fact, its underside is a clever trick of Mother Nature. On the underside, it is inconspicuous reddish-brown, with eyes to deter attackers. The bright iridescent blue, in turn, is to deter competition and attract females.

The three-fingered sloth: the facts you didn’t know about this impressive mammal

What’s with the fur? Why do sloths sleep so much? This month, the three-fingered sloth is the animal of the month at Adopt Rainforest. And what’s more fun than hearing from one of the founders of Adopt Rainforest some fun facts that you won’t find in a standard biology book. Maarten van der Beek is one of the biologists at Adopt Rainforest and lives on the Work With Nature reserve in Costa Rica. (more…)

Special glass frog in the reserve!

Now that student Sonny, a pure night tour specialist, is about to finish his internship, a lot of great discoveries are made at the last minute. To top it all off, last week we found a special glass frog in the reserve. This Hyalinobatrachium dianae – Diane’s Bare-hearted Glass Frog was only discovered and described […]

High time for biodiversity!

High time for biodiversity

Did you know that 5% of all species of flora and fauna in the world live and grow in Costa Rica? Also, Costa Rica is in the global top 20 countries with the greatest biodiversity! Are you a real nature lover? Then put Costa Rica on your bucket list. But… before you pull your backpack and passport out of the  closet, we want to give you a lesson about biodiversity. Maybe you have what it is, but to refresh your memory we’ll explain it to you in this blog. (more…)

Zoë on her wonderful experiences as a volunteer in Costa Rica

And then there you are, atop a hilltop, having a good cry. Or frantically trying not to let your fellow volunteer see how touched you are. My name is Zoë, I live near Hasselt in Belgium. I am an adult education teacher, and enthusiastic but very novice when it comes to nature. I would like to tell you about my wonderful experiences as a volunteer in the reserve of Adopt Rainforest.

Long-term research project with Utrecht University

Stichting Adopteer Regenwoud’s research project is entering an exciting new phase thanks to a long-term collaboration with Utrecht University. The foundation was ready for a new step to professionalize the research project and Utrecht University was looking for a stable and reliable partner in Central America to conduct solid research in the rainforest. So for both parties this is a wonderful collaboration! Because of this we will make a big step in professionalizing our current research on biodiversity in our reserve. Together with the visiting students we will focus on scientific research in which the diversity and development of nature in our reserve, with an emphasis on flora, is central.

Bird Watching in Costa Rica

Costa Rica, a country of which almost half is rainforest, is a true birding paradise. More than 900 species of birds can be found here. One of the most beautiful and special birds that has its habitat in Costa Rica, however, is the Resplendent Quetzal. A good reason to go bird watching in Costa Rica!

The rainy season part 1: Glass frogs

In the Caribbean lowlands of Costa Rica most rain falls in May to August. The fact that it rains is good for all life of course, but can be quite difficult for our biologists in the Work with Nature reserve; the paths become muddy, the laundry doesn’t dry and the project is sometimes briefly inaccessible because rivers are filling up.

Butterflies in Costa Rica

When a butterfly flies by, most people do stop for a moment to follow it with their eyes. They often have beautiful colors and the large soft wings compared to the small body make them look almost cuddly. In Costa Rica there are more than 1200 species of butterflies and of course we are very curious about the species that occur in the reservation of Adopt Rainforest.

The ceiba tree

The Ceiba tree, also called kapok tree, is an impressive sight with its trunk full of thorns and a growth rate of 2 to 4 meters per year. Those thorns allow the tree to protect itself from all kinds of animals. The tree is one of the forest giants of the tropical rainforest and grows […]

Strawberry poison dart frog

By Zoë Schreurs

In Costa Rica, you can’t ignore them: the Oophaga pumilio. Pumilio means dwarf, and although they are barely 3 cm tall, it is hard to miss the poisonous strawberry frogs. In English, they are called Strawberry Poison Dart frogs because indigenous peoples used to use their poison to makepoison darts. They are also affectionately called the “blue jeans frog,” because they often look like red frogs in jeans. Although they are by no means all the same colors. There are some that are completely red or blue, rather yellow, green or orange, or with black stripes or dots. In total, there are some 15 to 30 color variations.

Leaf-cutter Ants

Anyone who has traveled through the Americas knows them anyway, a stream of ants all carrying leaves with them. It looks like a mini highway that can go on for 30 meters. We’re talking about leaf-cutter ants of course. For tourists a source of amazement, for local farmers and vegetable gardeners a real plague that […]

The most special sighting in our reservation so far!

In recent years we have already seen many rare and unusual animals in our reserve such as the Northern Nacked-tailed Armadillo, Black-and-White Hawk-Eagle and several felines. However, what we recently encountered is many times more interesting to scientists. In 1989, Epigomphus houghtoni, the Limon Knobtail, a dragonfly species was described by Stephen Brooks based on […]

The Hummingbird

Most species are between 7.5 and 13 cm in size. You would almost think it is an out-sized bumblebee! Hummingbirds (Trochilidae) are the smallest birds in the world. They are a family of birds of the order swift-like. The family includes more than 300 species. Most species are found in South America. It is so much fun (more…)
