Shrike-like Cotinga

Even though it’s just a year since we published our last note on the sighting of the Shrike-like Cotinga in the recent news section of the web site, once again, birders are seeing this species on the lowlands in July.

We have the distinct feeling that it seems to staying longer on the lowland part of the reserve, before making its way up the mountains to disappear in January when presumably it is breeding.    Both Adilei and Cirilo, REGUA’s Bird Guides, have taken many guests to see this Neotropical species, one of the most iconic species of the Atlantic Rainforest.

Please come along to visit us at the British Bird Fair Rutland Water, UK from 17th to 19th August we shall be in Marquee 1, stand 37 where you can speak to our UK team to find out more about this and a host of other species and plan your visit to see them for yourself.

White-bellied Tanager

Though the IUCN states that White-bellied Tanager (Tangara brasilensis ) is considered of “least concern” it really is a stunning bird.

Flying in small flocks, up to 10 strong, this Atlantic Rainforest endemic can be found at REGUA even close to houses that make up its local villages.   It is very responsive to its call, and raises the neck feathers in retaliation to Adilei’s speakers.   It seems to like tree canopies at mid-elevation, but with the two tone powder blue plumage, black mouth parts and white underbelly it is unmistakeable.

As they appear quite mottled, one is left intrigued if the colourful feather arrangements are identical to all members of this species.

Recently renamed the White-bellied tanager; it has been split from its Amazonian cousin, Turquoise Tanager.    Those wishing to photograph this bird will not be disappointed.

 

Brown Tanager

The “Near threatened” Brown Tanager  species  (Orchesticus abeilli) like many tanagers, is an arboreal species generally associated with higher altitude forest where occasio

nally one can find it feeding with in a mixed tanager flock.    Seeing one in tree canopy is quite usual, but viewing one by the REGUA tower at lowland altitude appears a little out of place.

It is an uncommon tanager and habitat loss has not improved things for it, Serra dos Órgãos National Park, just two hours drive from REGUA, is one of several protected areas where this species has been found, but the risk of deforestation outside of the safety of Reserves such as REGUA and the National Park mean the species is becoming more isolated.

The Brown Tanager can be confused with the Buff-fronted Foliage-gleaner, the same rufous supercilliary line, but the typically “tanageresque” thick bill is the giveaway.   These birds like insects but will eat small fruit.

So why is it around? Another of Natures mysteries, but it certainly was thrilling to view from the tower offering great sightings and photographic opportunities to those with cameras and binoculars.

 

 

Tanagers

Whilst birders pack their binoculars, telescopes and long camera lenses to photograph the wonderful Neotropical birds at REGUA, we often reflect on why these colourful tanagers are found at different altitudes, as if the bird’s territories are indeed stratified.

In my garden, at low elevation, we often find the Green-headed tanager flying in mixed flocks together with Violaceous Euphonia and Blue Dacnis.

Occasionally a woodcreeper, xenops, ant-tanager and even a White-barred Piculet will share the flittering spectacle as they look for insects between leaves, for small fruit and any other tasty morsels.

However we do not find the mid-elevation Brassy-breasted Tanagers, whose busy flocks are only to be found at the higher altitudes.

Where can we see the Gilt-edged Tanager?   Occasionally they will be seen at the very top of the mountains or on the drier leeward slopes of the deciduous Mata Atlántica.

This shows us that these colourful beauties help to indicate the altitude, that tanagers aside from their natural colourful plumages are “stratospheric”  in more ways than one.

Long-tailed Potoo

Though Birdlife and IUCN state the Long tailed Potoo (Nyctibius aethereus) occurs across all South America, it also warns the population is declining.

The species refined distribution map suggests that in some time the Atlantic Rainforest and the Amazonian species might well be split.  This magical bird is rarely seen and highly desired by most bird observers around the globe.  With its nocturnal habits, its call is a long loud “Raaauuulll…” and the local population is scared by its unexpected call.

It is usually found perched on snags and high stumps and although it’s a large bird, it is well camouflaged and slow to move that often one just misses it.    This species requires good habitat and we are lucky to have one that doesn’t mind being photographed.

Lee Dingain spent lot of time observing this species and wrote an excellent paper that was published in http://regua.org/wp-content/uploads/2017/02/nb10-ltpotoo-dingain.pdf

Dragon Praying Mantis – Projeto Mantis

The Mantis Project is made up of Brazilian biologists Leonardo Lanna, Savio Cavalcante, João Felipe Herculano and designer Lucas Fiat, who are very keen on insects.

They met at UNIRIO University in 2015 and soon discovered that there was no-one studying the impressive Mantis order, Mantodea.    There are over 430 genera and 2400 species divided in 15 families worldwide and they believed there could to be many in the Atlantic Rainforest.

Leonardo and his friends got together and started their first field trips in Valença a town in the South-West of Rio State and the following year caught an undescribed species, a first for science.   Their primary interest was not in just finding and identifying these amazing creatures but also raising Mantises, showing people that these insects are not dangerous or life threatening but beautiful, gentle creatures that indicate the quality of the habitat.

With their increased passion the Team started to work at Rio de Janeiro’s Botanical Garden.   They submitted a project to National Geographic in 2016 and received the funding to research the State of Rio and increase the list of the 12 genera already known there.

However, Rio de Janeiro state is very large and their study varied from sand dune habitat known as “Restinga”, Mangrove habitat to the lofty “Paramos” or sedge growing waterlogged habitat found at close to 2,600 metres above sea level in Itatiaia (two hours drive west of Rio city) where temperatures fall below zero at night in the winter.

The team also included REGUA in their research and arrived to stay at its field station in December 2017.

One mystical Praying Mantis is the Dragon Mantis, Stenophylla cornigera described by English entomologist John Westwood in 1843.   It resembles depictions  of miniature dragon and the young biologists had never seen one.    Imagine their delight when on the first night, an example arrived at the REGUA light and they could see it in full detail.

The team of biologists collected not only one.    A second was found a couple of days later from a forest fragment just seven kilometres away, showing that the species is present along the Guapiaçu valley.    A report and video was sent to National Geographic magazine which was hugely successful.
See https://news.nationalgeographic.com/2018/01/animals-insects-brazil-rainforests/

The overall research revealed another nine genera taking the total Mantodea list in Rio de Janeiro State to 21 genera, of which 15 have been found at REGUA.

Leonardo says that REGUA is at an elevated level of habitat protection.   Perhaps the significant area of remaining forest cover, full altitudinal gradient and low demographic pressure all influence but the fact is that as an indicator species, Praying mantises reveal that the REGUA conservation project is working in the right direction.

A big Thank You to all REGUA supporters!

REGUA welcomed retired RSPB director Stuart Housden and Alan Martin recently.   Although Stuart is familiar with the project and had visited REGUA before, he is now a Brazilian Atlantic Rainforest Trust (BART) Trustee and the aim of the visit was to learn what REGUA does; why its work is so valuable and how he could help us with his vast experience.

It is amazing to think that we started this off in 2001 with a plan to protect a part of the Atlantic Rainforest at REGUA and almost two decades later, this project is attracting international and national attention for progress in all of its programmes, be it in administration, protection, research, education, restoration or tourism.

REGUA’s location is privileged in that it is set in an area that still retains a significant amount of original biodiversity.   It is also just close enough to Rio de Janeiro city and its environs to make a day outing, an overnight stay or longer visit easily viable.

The factors that contribute to the biodiversity are various including; area of remaining forest cover, a forested gradient and fundamentally an understanding local community, be it land owners, farmers or the local population.    We started our conservation programmes 20 years ago with international support as funding within Brazil was virtually non-existent. Today we see the fruit of what we planted and the results today of every programme speak for themself.

Possibly the best thing about REGUA is that there are so many things to do, it has an exciting aura around it as ever more people are visiting and we can show positive results. The forests are returning the hillsides and valley, the biodiversity is improving, more land is put into set aside, more visitors and the community are learning and approving of our actions and we are getting bolder with our convictions.

So, although Raquel and I are getting older, we are keener than ever to gain improved results.   Through sharing experiences and knowledge, your visit helps us stride firmly towards the future.

A huge thank you to our UK volunteers, Lee, Rachel, Sue, and to Alan for having been champion king pin for so many years, and now Stuart who together with our mother charity BART and its Trustees endorse our actions and want to help us reach further towards the future.

On both sides of the Atlantic, we have marvellous teams and Raquel and I can firmly say that your determined support has made the difference!

If you would like to meet our UK Volunteer Team they will be at the British Bird Fair, Rutland Water, 17th-19th August, 2018.   Pop along and say hello, Marquee 1 stand 37

New damselfly species discovered at REGUA by Tom Kompier

We are delighted to announce that a new Damselfly species for science of the Forcepsioneura genus found at REGUA by Tom Kompier has been named Forcepsioneura regua sp. after the reserve. This is one of two new damselfly species described by Dr. Ângelo Pinto with Tom as co-author in their paper In honor of conservation of the Brazilian Atlantic Forest: description of two new damselflies of the genus Forcepsioneura discovered in private protected areas (Odonata: Coenagrionidae), published in the zoological journal Zoologia.

Tom’s contribution to our knowledge of dragonflies and damselflies has been magnificent and provides valuable evidence of the importance of this reserve. He started his research in 2012, making several visits during the varying Neotropical seasons, travelling from the Netherlands to REGUA throughout 2013 and identifying 204 species in this region. Tom was supported by Dr. Ângelo Pinto and Professor Alcimar Carvalho of the Natural History Museum/UFRJ. This resulted in the publication of A Guide to the Dragonflies and Damselflies of the Serra dos Orgaos, South-eastern Brazil (see details on our publications page).

The principle difference between dragonflies and damselflies is the position of the wings when resting. Dragonfly wings lie transversal and damselfly wings lie flat alongside their abdomen. 204 species have been recorded at the reserve and REGUA hosts annual visits to see the odonate and in an eight day visit it is possible to see at least 160 species!

Congratulations and thank you Tom for the magnificent contribution your work has given us and you have inspired us to continue to develop studies in ants, butterflies and spiders.

Second Tapir release begins!

Following the arrival of three lowland Tapir (Tapirus terrestris) at REGUA last January, a further two males and a female named Jupiter, Valente and Flora arrived at REGUA in Guapiaçu as part of the continued Tapir reintroduction programme at REGUA on Sunday June 10th.    Sadly, we sustained the loss of the large adult male from pneumonia in March so these three new individuals were a most welcome addition to the remaining population, a mother and adolescent tapir who are very well.

This reintroduction project has been carried out in partnership with Professor Fernando Fernandez, Maron Galliez and Joanna of the Federal University of Rio de Janeiro (UFRJ) and approved by the Rio de Janeiro State Environmental Department (INEA) as well ICMBio.

The tapirs arrived after a tiring 24 hour trip of over 1,000 km from the Klabin conservation project in Northern Paraná State. They were transported in their travelling cases but had behaved admirably and arrived quite calm.

Following much local interest, the cases were promptly taken to be unloaded and released in their two and a half acre quarantine pen created especially for them within a secluded part of the wetlands. The quarantine area has a small pond in which to play and enjoy.

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 its kind in Rio de Janeiro state.    REGUA starting reforesting lowlands in 2005 with the support of the World Land Trust and in 2005 created RPPN status which protects these restored forests for the future.

Lowland forest has virtually been eliminated in the State and REGUA’s protected area of 300 hectare Atlantic Rainforest adjacent to the enormous Três Picos State Park looked a very attractive area that could guarantee sufficient habitat for the species.

Being herbivores, tapirs consume all the fruit they can find on the forest floor. Feeding on fruit and walking large distances in the forests, they are regarded as the ‘gardeners of the forests’. The UFRJ team understood the need for reintroductions as a means to learn more about this species and their adaptability whilst REGUA wants the animals to spread tree species, increasing forest diversity and ensuring its resilience on the long term.   Likewise, captive breeding programmes are only too delighted to support such well conducted release programmes as it provides the justification for breeding these lovely animals in captivity.

Until their supported release, and like their predecessors Eva and Flokinho the three tapirs will enjoy a diet of fruit and vegetables, up to 8 kilogram per animal per day together with dried maize, to keep them well nourished.  Professors Maron and Joanna will keep their eye on them ensuring that the radio collars are not bothering them and they like their diet. After their release they will find fruit and maize nearby, but like most native animals they will probably prefer to roam and return to the solitary lives they enjoy.

Their release will provide valuable information as to their wanderings and habitat preferences, but there are already camera traps in the pen to check on their nocturnal behaviour and later more will be placed in the forest.

Exciting times ahead for our tapirs and for our biologists!!

Rufous-sided Crake

Rufous-sided Crake (© REGUA)

The Rufous-sided Crake (Laterallus melanophaius) is one of my favourite wetland bird species.   Walking around the wetlands, if one hears a shrill resembling a rising crescendo, you can be sure that this little bird is quite close, yet very hidden.

To see it is quite another matter.   The Rufous-sided Crake’s distribution is limited to Brazil and bordering countries, and though it’s considered “least concern”,  not much is known about it as it is so incredibly secretive.

They are best found if you are walking around the wetlands early morning or late afternoon when if you are quiet, you can get good views of this bird as it scuttles across from one lake to another or watch as it probes around for small insects to eat.

Sometimes they forage in pairs and move around very quickly.   The colours are gorgeous and when a little light catches the rufous feathers, it gleams.

What a memorable sight!!
