The Tapir re-introduction team comes to Regua on a weekly basis to check on the well-being of the Tapirs and to talk to community neighbours about this project.
The Young Rangers were thrilled to hear from Joana the Education Officer from the Tapir Reintroduction programme, that the Tapirs are becoming more independent from the food provided for them and that they are moving further away from the release-pen as each day goes by.
Prof. Carlos and the young rangers will be visiting the local villages of Guapiaçú, Santo Amaro, Areal, Matumbo and Estreito to inform the communities on the positive development of this pioneering project.
The tapirs still haven’t been fully released into the wild but their pen surrounds a large inlet of water and in the heat of the day both adults, baptized Adam and Eve, enjoy staying in the water to savour the coolness.
Adam has a radio collar attached but Eve’s collar was removed to let a sore heal. Seeing two tapirs wallowing in the protected and natural habitat at REGUA is quite a sight!
We are hoping for a soft release by the end of February – more news to follow!
The Southern Muriqui (Brachyteles arachnoides) restricted to the Serra do Mar mountains of South East Brazil and classified as “endangered” on the IUCN red data list, used to have a much larger home range.
Sadly forest loss, fragmentation, timber extraction and urban expansion reduced its home range area and today the sighting of this magnificent species is really rare. Some retired hunters have never seen them!
Rildo da Rosa Oliveira is one of REGUA’s team of rangers. Rildo, who is funded by the World Land Trust “Keepers of the Wild” programme, caught these amazing photographs of the species with young of various ages indicating the population is stable and healthy.
Rildo (himself an ex-hunter) is engaged in helping University researchers in their studies. REGUA likes to promote research in the Reserve as a means to maintain a positive presence in the forests which are home to peccaries and pumas, the Solitary Tinamou and the Variegated Antpitta as well as important tree species. Maintaining a low impact and constant presence dispels the hunters and charismatic important species such as the Southern Muriqui become less flighty over time.
These animals are now being more regularly sighted and specialist André Lanna suggests REGUA might be home to the largest population of the Muriqui in South East Brazil, or the world for the matter, as the species is endemic to this region.
REGUA wishes to thank the World Land Trust for their support that permits ranger Rildo to keep a whopping 2500 hectares free for the species and the forests of hunters.
The introduction of the Lowland or Brazilian Tapir Tapirus terrestris at REGUA is going very well. The two adults (previously referred to as Napoleon and Daphne) have been baptized ‘Adam’ and ‘Eve’ by the REGUA Young Rangers and the one year old calf (previously named Frank) has been given a new name, ‘flokinho’ or ‘Snowflake’ – probably because you see him very rarely here in the forest. He regularly wanders in and out of his release pen and ventures around the entire lowland area.
The researchers have been doing a great job and attached a radio collar to both adults and the programme is going according to schedule. For those who have never seen a tapir running in the forest, this is an opportunity not to be missed. They run faster than a champion Samoan rugby player with a similar frame and promptly disappear into the forest. There is a great pool in their release pen in which they can wallow and the adults love relaxing.
These tapirs are just terrific animals and although we are providing a fruit and vegetable supplement, they much prefer browsing the natural vegetation. They appear to enjoy nocturnal activities and we are set to release them at the end of February if all goes well.
Based on their and our learning, more will follow.
Southern Tamandua Tamandua tetradactyla are not often seen at REGUA, with previous records including one in the lodge garden and another found dead in the forest at the wetland several years ago.
But last November our bird guide Adilei Carvalho da Cunha was lucky enough to find one on the Red Trail and managed to capture some excellent video of the encounter.
This member of the anteater family is found in a variety of habitats from mature to disturbed secondary forest and arid savannah, although it is thought to prefer living near streams or rivers. Feeding on ants and termites they will occasionally take bees and honey. A solitary species, Southern Tamanduas are mainly nocturnal, although as can be seen here, they are sometimes found during the day and this individual seemed to be completely at ease with Adilei’s presence.
It’s great to see this enigmatic creature in the forests at REGUA and this sighting is another indicator of the improvement our reforestation has made to the biodiversity of the forest environment.
After five years of planning we are delighted to announce to arrival of three Lowland Tapir Tapirus terrestris at REGUA, a male, female and calf.
This reintroduction project has been carried out in partnership with Professor Fernando Fernandez of the Federal University of Rio de Janeiro (UFRJ) and his team and Rio de Janeiro State Environmental Department (INEA).
The tapirs arrived yesterday afternoon after a tiring trip of over 1,000 km from the State of Minas Gerais. Their travelling cases were unloaded and taken to a specially prepared pen created in a secluded landscape where the animals can become accustomed to their new environment.
For a while we will provide fruit and vegetables for them to eat – up to 8 kg per animal per day. During this stage strict guidelines will be followed to ensure they do not become habituated or reliant on the provision of food.
The Lowland Tapir has been extinct in the state of Rio de Janeiro for over 100 years and the arrival of these animals at REGUA represents the very first reintroduction of tapirs in Rio de Janeiro state.
Our forests have lost their largest land mammal and one responsible for spreading the seeds of many trees and ensuring the strength and health of a forest – often referred to as the ‘Gardener of the Forest’. With the return of the tapir, REGUA will have great help in the regeneration process of the forest. Here’s wishing our new tapir family a successful future!
Sylvia and Chris Knight visited REGUA recently with their two children, and one of the tasks they undertook was to see how many different seeds they could find in the forest.
However, that was not the only thing they did in their visit – here’s more from Sylvia.
“As a family, some of the real highlights were our night-time walk where we were spotting caiman, opossums and nightjars as well as other sightings of sloths, a gorgeous orange spined hairy dwarf porcupine, two male blue manakins displaying to a female, watching 1743 cattle egrets come in to roost, and so much more.
We’d like to reiterate our thanks to all the people at REGUA who made us feel so welcome, and made our stay so enjoyable by ferrying us around, feeding us, finding us incredible wildlife and answering a lot of questions!
Crab-eating Fox (Cerdocyon thous), is quite a common South American mammal confined mainly to Brazil, Argentina and Paraguay, and labelled “of least concern” on the IUCN red list.
It is seen mostly on open areas and on REGUA’s lowlands this is no exception. They are most often seen at REGUA on our night excursions when caught in the torchlight as they roam the fields around the Reserve. It is, however, a timid animal and if one is fortunate to see one streaking across the road and into the bushes to hide, the observer is left content.
Adilei (REGUA resident Bird Guide) was walking the Yellow Trail by the wetlands recently and came across this resting female lying on the path. As Adilei crept up to steal a closer image, she jumped up and took off. Sadly you cannot see its fine bushy tail.
Inspired by my Grandfather’s (Helmut) stories of adventure in identifying orchids and my Father’s (Klaus) passion for snakes, I visited REGUA as a volunteer in 2015. I want to pursue a career in biology and my focus then was on which mammals venture to and from the wetlands and which routes they choose to take, using camera traps positioned on visibly active animal trails.
I showed that trail building in an around the wetlands is almost exclusively done by the CapybaraHydrochoerus hydrochaeris, that permanently live in the wetlands though other animals would also use their trails. These animals like to use the main tourist trails, but between the wetland lakes and the major routes also exist a network of minor “social” trails.
The Capybaras’ stronghold at REGUA is the wetlands but they leave the wetlands for feeding. This was done on three major routes leading to neighbouring farmland, adjacent wetlands and into reforested rainforest with remnant pastures.
I returned to REGUA in March 2017 and observed that all the major routes still existed. There was no change in the trail network although there was an obvious change to where the Capybaras stay during daytime. The object of my stay was to determine how the Capybaras live in the wetlands.
Based on different counts I estimated that there were 50–70 Capybara living in the wetlands in March/April 2017. These numbers were less than we expected. I did not count them in 2015, but I have the feeling their numbers have declined. In 2015 there were seemingly two major groups of Capybara and they were apparently present everywhere in the wetlands. But this was not the case this year, when there was only one group left and other individual Capybara were scattered.
In 2015 I also noticed that many Capybara had wounds and cuts especially on their rear body parts. Some were seriously wounded and were noticeably limping. They seemed to be quite aggressive between each other and I could witness several moments when Capybaras bit each other. The wounds were not as obvious this year. Fighting still took place but the wounds were not as numerous and not as severe. I have the feeling there may have been over-population in 2015 and the lower numbers could have diminished social pressure in 2017.
I also observed that only the group near the volunteer houses remained and concluded that the animals also formed “Capybara nurseries”. A group of 20-30 Capybaras would gather on an island and look after the new born and young less than six months of age, guarded by three to six adults. The young were clearly protected with the adult guards looking in every direction supervising the group. This nursery island was abandoned about one hour after sunrise each day, the young guided to their day area and to other Capybara groups. The majority of Capybaras live loosely dispersed on the shores and islands all over the wetlands.
Aside from the nursery, I could not find evidence of a constant group of Capybara larger than five animals during my three week study. I could not mark any Capybara and there are no individual markings on any Capybara body to distinguish them apart. From the pictures of the camera trap I could see that there were no uniform constant groups. Capybara would go alone or form differently composed groups daily.
Over the past three years there was a noticeable relocation of the Capybara population towards human housing especially during night time. This behaviour could be the result of a clear increase of larger predators in the wetlands. We have seen at least three large Broad-snouted Caiman Caiman latirostris longer than two metres and there was a clear evidence of an increase of big cat activity in the wetlands. I had read tales from African safari camps of alternating behaviour of animals with young moving towards humans to avoid their predators.
It is possible that the whole population of the REGUA wetland Capybara are in fact a loosely connected society but their behaviour may vary seasonally. This has to be verified.
The REGUA wetland Capybaras give me the impression of a healthy population that very well adapts and regulates itself by wandering off to the adjacent habitat and perhaps also through increasing predation. For future work on the Capybara and to study their social behaviour I will have to find a way to mark individual Capybara. Radio tagging would only make sense when and if we could get funding for a major work on Capybara.
There are excellent conditions to study the life in nature of Capybaras and other wildlife at REGUA because wildlife is diverse and abundant and almost free from human pressure. I look forward to returning and conducting further research work at REGUA.
Raquel went seed collecting recently with Barata and Mauricio as we are always on the lookout for seeds to plant in the REGUA nursery.
January is a good month to collect seeds and many species were laying on the forest floor. High on the Orange trail, Barata suddenly came across a small den and upon closer inspection found the extraordinary remains of a Collared Peccary, Tayassu tajuco.
These are mainly fruit eaters and have been regularly caught on camera traps in large groups foraging for food amongst the vegetation.
It is quite a common species found across the Americas but the sight of the huge skull with its large canines is still most impressive. Barata had never seen one before and Raquel has a good example to captivate our visitors’ attention.
