REGUA are delighted to be able to attend the Virtual Birdfair which is taking place online this year. So although travel throughout the world is disrupted the Bird Fair will still be there, just a click away.
REGUA will be present, and the Team will be with you all in spirit throughout the weekend. Once live we will publish a link to bring you closer to our “stand”.
All the usual favourites will be there with live and pre-recorded talks, films, a photography competition and the familiar auction.
The full Birdfair programme of lectures and events will be fully operational from 18th August until the 23rd August but until then you can follow the link to Virtual Birdfair here to take a look at the first Virtual Birdfair.
When Brian Rodgers came to visit in June, he brought his drone with a new lens that promised great opportunities. The drone offers remarkable views that can really capture the beauty of the landscape here at REGUA, it is also a very necessary tool to help us understand the importance of the conservation work going on.
Supported by Saving Nature, Brian arrived with two students Ian Handler and Ryan Huang from Duke University, in North Carolina, USA. Their plan was to help set up camera traps, in strategic places around the reserve, and also to continue their scientific research at the Golden Lion Tamarin project in Silva Jardim.
Brian helped REGUA secure the Vecchi land corridor last year, an important strategic purchase to link the Vecchi ridgeline with Onofre Cunha, land which REGUA already owns and protects. Brian was delighted to see the progress we are making in planting this pasture land to create a forested link.
This diurnal snake, was seen by a group of visitors on our Green Trail, whilst walking in the forest with Adilei.
Although not venomous, they can still give a nasty bite if threatened. Adelie knows how to deal with this sort of situation as he has spent all his life in these forests. One of the group got this amazing footage, standing at a safe distance.
These snakes lay eggs and are active on the ground and in trees. Their prey are mammals and birds, including eggs and nestlings.
Their defence strategy is to puff up their forebody and shake their tail. This individual seemed quite relaxed and only shook the tail as it left the group by slithering under a nearby fallen tree.
Michael Patrikeev, recently sent us this photograph of the rarely seen Idomeneus Owl-Butterfly Caligo idomeneus, taken at REGUA on 14 September 2010.
Jorge Bizzaro, REGUA’s Research Coordinator, and very knowledgeable lepidopterist explains why this species is rarely encountered. “This individual from REGUA is a rarity, because it only flies during sunrise when most lepidopterists are sleeping! The main characteristic of Caligo idomeneus is the very straight and defined median white band of the forewing present on both sides.”
Michael Patrikeev, a long standing friend and supporter of REGUA is always coming up with amazing information on his sightings while at the Reserve. The latest concerns two species of large grasshopper found at REGUA. Here’s Michael’s report and excellent photographs.
“I have identified two species of Tropidacris from REGUA
Tropidacris cristata (Giant Red-winged Grasshopper) is the largest known grasshopper, reaching up to 14 cm in length, and 24 cm wingspan. The adults are olive or brownish-green, with orange hindwings. The nymphs are striped with black and yellow, and likely toxic. This species inhabits forested areas of Central and South America from southern Mexico to northern Argentina, and the island of Trinidad. In flight it resembles a small bird.
Tropidacris collaris (Giant Violet-winged Grasshopper) is found in tropical forests and grasslands of South America east of the Andes, from Colombia to Argentina. Along with T. cristata, this is one of the largest known grasshoppers (length around 10 cm, wingspan 18 cm). The adult is mostly green, yellow-green or brown, with blue hindwings. This species is more common than T. cristata.
I have photographed only nymphs of these species in REGUA, but would expect one of these to come to a light at the Reserve sooner or later – they are quite a sight!”
Both species are widely distributed in the Neotropics, and common. T. collaris occurs in both forests and savanna, and T. cristata is mostly a forest species.”

It’s amazing how things can change in a year. It’s just over a year since I was last at REGUA, and so much has happened.
Most noticeable to the lodge visitor is the tapir release project where five Lowland or Brazilian Tapir (TapirusTerrestris) have been released at the nearby wetlands, they often make the short trip up to the lodge garden. It is surreal to see guests at night photographing moths at the moth wall, with a rather large mammal wandering past on its evening patrol, both seemingly unaware of the other.
The Tapir have managed to get food off the garden feeding stations so a suspended higher-level table has now been made. The Common Marmoset (Callithrixjacchus) were a little perplexed initially but soon mastered the art of a trapeze-style dash across the wires. Some continue the more traditional approach – head first down a nearby tree.
The lodge orchid garden continues to develop, and with ferns and bromeliads amongst the rocks it makes a breeding area for house wren and feeding area for hummingbirds, the lantana and milkweed are doing well, again both favourites with the hummingbirds.
Other changes may not directly affect our lodge guests but they are making a huge difference to local visitors, including school visits, with a new car park by the conservation centre – hopefully no more buses getting stuck in the mud! A new accessible trail has been created to Amanda’s hide, bringing opportunities where previously it would have been impossible for some people to enjoy the delights of the wetlands.
On the project itself, we reached the milestone figure of 500,000 trees planted and continue to plant – over 69,000 trees were planted in the 2017/18 planting season alone, thanks to the generous donations from many of our supporters.
Wouldn’t one million trees planted be a great figure to reach in the future!
With more key land areas coming under REGUA’s care, increased wildlife corridors are being protected and created in the Guapiaçu catchment area. This will extend the range for many species of wildlife and enable them to strengthen in population, increase genetic diversity and increase the overall biodiversity of the valley.
Our Rangers continue to patrol the forest, adding security and monitoring the wildlife, whilst there has been a huge reduction in hunting in the area since the project began, we cannot stop our vigilance even though there is very little evidence of hunting seen or heard now.
If you would like to support REGUA’s work, full details on how to make a donation are available from our “donate” page here.

Climate change is predicted to increase the intensity of extreme climatic events such as severe droughts. Littleis known on how freshwater ecosystems respond to severe droughts in the neotropics. Terrestrial organic matter, primarily derived from plant litter, represents an important food resource in these nutrient limited freshwater ecosystems.
ThePhDprojectcurrently being undertaken by Camille Bonhommefrom Universidade Federal do Rio de Janeiro(UFRJ) wants to investigate the effects of quantity of terrestrial mattersubsidies on the response of the recipient aquatic communitiesto drought stress.
Camille will use tank bromeliadsalong with their associated aquatic invertebrates as model ecosystems. Tank bromeliads are neotropical plants. Their interlocking leaves form rosettes that collect rainwater and dead leaves from the overhanging trees, creating an aquatic habitat for various species of invertebrates.
In the field experiment, bromeliads will receive either few or high quantities of leaf litter inputs. After a natural colonisation and equilibration period, the diversity and composition of the aquatic invertebratecommunity that colonised the bromeliadswill be assessed and compared to the quantity of subsidised resources. Thebromeliad micro-ecosystems will then be submitted to a drying and rewetting event, to assess their resistance and resilience.
Camille hopes to show firstly that the variations in leaf litter provision will determine the composition and quality of the colonisation (includingnumber of species, food chain length and overall community composition).
Secondly, that the leaf litter quantity will affect the stability of the community submitted to drought, expecting the higher provision of leaf litter to give greater support, by offering a “buffering” effectto the community. It is hoped to show that leaf litter will provide short term refuges for invertebrates and be more attractive for recolonisation after the drought.
We look forward to seeing the result of Camille’s research.
Last weekend REGUA received Thomas Brooks, Head of Research at Geneva for IUCN.
In between seeing birds in the day and waiting for the owls to call in the evening, we discussed the importance of monitoring, something talked about at the recent World Land Trust conference in Thetford UK.
He also asked us about long term sustainability. I told Tom that we believe REGUA will continue to grow and reach to tourism, education and research income streams and that we look at the protection core costs such as Ranger work being covered by Eco-service payments.
As there is increasing evidence that forests produce water, we believe that grants will be available in the near future that provide annual fee given to those proprietors who have forest cover.
Ants belong to the Formicidae family, one of the most important in Nature, pillars of the ecosystem. Divided into Tribes, the Attaand Acromyrmex are very common in our Neotropical forests and though we worry about their action in freshly planted forests, they are very important in the established forest harvesting and cultivating their fungus on which they feed in their underground homes.
Their vast system of perfectly ventilated tunnels and chambers permits precious nitrogen to reach the roots of trees.
We are trying to identify the most common species at REGUA but we expect to have between 400 and 450 different species. Taking photographs is notoriously difficult, for aside being small, they move and are often camera shy.
If you want a challenge and wish to visit us spending your time helping us to get some images to help with developing a field guide, drop us a line and we would really love your company.
One of the newest projects at REGUA is the creation of an orchid and bromeliad garden at the lodge. This is a small area to the side of the lodge veranda and was the brainchild of Nicholas Locke, REGUA’s President.
Huge rocks were delivered earlier this year and moved into place. There are also some well weathered orchid posts which have proved very effective in the front garden of the lodge so we are hopeful that they will soon house flourishing exotics. Bromeliads are already in place – all found on fallen branches around the reserve.
Over time more plants will be added, including ferns, and will provide an excellent opportunity for lodge guests to easily see plants that are only too often found high in the canopy.
The garden is sited along the north wall of the lodge ensuring that the plants are in a shady environment. Netting has been added to give further protection. House Wren and Masked Water-Tyrant are already using the area to search for food and a Yellow-headed Caracara has found a good look-out post!
Introducing the Guapiaçu Grande Vida Team for their second project at REGUA. Following the successful reforestation of 100 hectares of cattle pasture along the edge of the River Guapiaçu in 2013-15, the second project is now underway.
This time a 60 hectare plot is being planted, on steep and highly eroded land along the road on the way to our Waldenoor Trail.

Ever wonder what the loudest bird on Earth is? The outrageous Bare-throated Bellbird (Procnias nudicollis) is certainly a top contender! While hiking up the Green Trail here at REGUA, singing males can be heard from over a kilometre away.
The call each male belts from his featherless blue-skinned throat sounds like a mallet striking an iron pipe, and echoes down the valley in rhythmic series. As we climb higher up the mountain trail, the boinks and bonks of competing males get louder and louder, but we can often only catch glimpses of them perched high in treetops.
Today, volunteer bird guide Bobby found our lucky visitor group, front row seats to an ear-splitting performance by a young male singing close beneath the canopy. Bare-throated Bellbirds are endemic to the Atlantic Forest, found nowhere else on Earth. These large, fruit-loving passerines perform crucial seed dispersing services for many lowland and montane trees. Unfortunately, drastic logging of the Atlantic Forest for development, combined with illegal poaching for the caged-bird trade, has led to declining populations of this spectacular species and a Vulnerable designation by IUCN. But thanks to REGUA, the forest home of these contending males along the Green Trail is safe into the future. And they can return the favor by dispersing their favorite fruit trees throughout the reserve, helping the forest to grow!
As I was patrolling the Brown Trail today, I noticed a pair of Silvery-flanked Antwrens (Myrmotherula luctosa) gathering dry leaves and taking them into the branches of a small tree. I carefully followed their lead and discovered a little cup nest taking shape! In order to avoid disturbing their work with my observation, I set up my camera on a tripod and left.
This short highlights reel reveals that male and female team up to weave a safe place for raising a family.

Kaitlin and Bobby are currently volunteering at REGUA. Their main project is to help Adilei and Cirilo show the wonderful bird- and wild-life to visitors, but they still find time to do some exploring . . .
“Today Bobby and I were asked to survey a potential trail that winds through an area reforested in 2011-12 with the help of Petrobras. We were amazed to see such a dramatic amount of growth for such a short amount of time, as well as the diversity of tree species used to jumpstart this section of forest which was once open pasture. Most of the trees were well above our heads!
It was a hot and sunny day, which can effect bird activity, but we still managed to count over 40 bird species using the area already! It will be exciting to see how species composition changes as the forest progresses.
On August 24th, Regua hosted the Inaugural RPPN(*) or “Reserva Particular do Patrimônio Natural” Scientific Seminar in Rio de Janeiro state.
INEA – Rio de Janeiro State Environmental Agency – encourages land owners to create their own private reserves which are officially recognized by the state government. RPPN status allows no direct use of the land but allows activities such as environmental education, sustainable tourism and scientific research to be carried out. Much of REGUA’s land has been granted RPPN status and three new areas were finalised last August.
There were over 100 participants attending the event that started in the morning and continued until the evening.
Studies on forest ecology, flora and fauna inventories were presented to a very interested audience.
Land owners, university professors, undergraduates, post graduates, state and municipal authorities enjoyed this seminar which enriched everyone´s knowledge on the Atlantic Forest.

Andrew Proudfoot, REGUA Volunteer, reports on research work at REGUA.
“The two men in the middle drop in onCaio Missagia (right) who, helped by his friend Juan, is working towards a doctoral thesis on the intricate relationship between Heliconiaspathocircinata, three Hummingbirds (Violet-capped Woodnymph, Reddish Hermit and Saw-billed Hermit) and a Hoverfly (Syrphidae) and Soldierfly (Stratiomyidae) species.
Who benefits, who loses and by how much? Heliconia needs pollination visits from the hummingbird and could provide a plentiful nectar reward. Larvae of the two fly species are kleptoparasites, gorging on the sugary tissues deep within the protected bracts of the plant’s familiar boat-shaped flowers. If only those paired bracts were more open, marauding ants might rid the flower of its freeloading flies.
The Amazonian species has no hiding place for Diptera larvae and perhaps it has no trouble supplying its pollinators with nectar. Natural selection could have driven the development of a less enclosed host plant flower. As the Heliconia provides less resource for the hummingbirds, what is the impact on pollinator behaviour and fitness? Fewer birds are recorded visiting infected flowers.
As yet, Caio has no clear answers to these important questions and whether or not Heliconia spathocircinata might be pushed to control these unwelcome freeloaders? An unfolding story; at REGUA we await the next instalment with excitement!”
Michael Patrikeev has been working on the identification of species he found at REGUA during his stay and has more news for us.
“I have identified another species for the reserve this time it is a giant black-blue spider-hunting wasp, which has very likely been seen when it was busily looking for its prey in the forest understorey. The size is impressive, 50-55 mm, and its sting is very painful, apparently scoring 4.0 on the Schmidt sting pain index, next to the bullet-ant (4.0+).
The species is Pepsis inclyta Lepeletier, 1845. It is “commonest in southern Brazil to central Argentina, but ranges over most of South America” (Vardy 2005).
