In October 2017 our bird guide Adilei Carvalho da Cunha heard a Great Horned Owl Bubo virginianus at the village of Matumbo, situated at the edge of REGUA. With a large range covering much of North, Central and South America, Great Horned Owl had long been predicted as a future addition to the REGUA bird list, but this was the first record for the reserve.

Tantalizingly, there was no further sign until just a few days ago on the 18 August 2018 when Adilei finally saw a bird – the first sight record for REGUA. When he returned the next morning with his camera he found not one bird but a pair! Then while watching and photographing them he was amazed when they mated right in front of him!

What an incredible record and yet another owl species for REGUA. The addition of Great Horned Owl takes the REGUA bird list to an incredible 479 species! Well done Adilei for finding and documenting such a great record.

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

Black-fronted Piping Guan Reintroduction – update

The story of the reintroduction of Black-fronted Piping-Guan (Aburria jacutinga) at REGUA continues.

Alecsandra Tassoni,  is SAVE Brasil’s Black-Fronted-Piping-Guan project coordinator and will be visiting REGUA to supervise the arrival of the birds.

The two females and one male come from a captive-breeding project in Paraná state. Their health tests were undertaken at UENF (Universidade Estadual Norte Fluminense) in Rio de Janeiro state prior to their transfer to São Paulo where they are currently being monitored.

Scanning and observation are the techniques used to study their behaviour which include assessing their food demands.  There will also be predator training to ensure the birds react naturally to predators once they leave their release pen.

The Black-Fronted-Piping-Guan reintroduction project at REGUA is funded by ‘O Boticário’ cosmetic company which is a long- standing Birdlife International partner.

REGUA looks forward to the next exciting part of the story.

Rufous-sided Crake

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!!

The Moustached Wren (Pheugopedius genibarbis) is quite a common Troglodyte here at REGUA especially around the wetlands.    A largish bird with unmistakeable black and white facial stripes, rufousy coloured back and wings, creamy under parts and the characteristic banded tail, it can be found in low undergrowth with its musical chirp feeding on insects.

Adilei attracted this male out of the brush and they had their moment of recognition, a brief duet and off he was looking for his insects.
