BRAZIL 2010: Threatened Birds |
|
|
Birdlife International maintains the official IUCN list of Threatened Birds
of the world. In its book (Birdlife International 2000) it categorized
1186 species in 3 categories — Critically Endangered, Endangered,
Vulnerable — and over 800 species considered Near-Threatened. The list
is updated annually. By 2010 — the time of our trip to Brazil — there
were 1240 species in the three most threatened categories, and 838
considered Near-Threatened. This is ~13% of the 9895 birds in the world
at that time.
Brazil has
more globally threatened birds than any other country. Of the 111
species at risk of extinction, 98 live in Brazil’s Atlantic forest,
already the country’s most seriously reduced habitat. During our trip
we encountered one Critically Endangered bird, three Endangered
species, nine Vulnerable birds, and 22 Near-threatened species (as
adjusted to 2010 status). This page highlights our observations of
these interesting birds. |

CRITICALLY ENDANGERED |
CONE-BILLED TANAGER
Conothraupis mesoleuca
First
discovered in 1938 in "dry forest habitat at Juruena, central Brazil,"
this bird was a mystery at the time of the publication of Threatened Birds of the World
(2000) as it had not been seen in 62 years. In 2003, bird guide
Bráulio Carlos rediscovered it along the Formosa River in Emas
National Park, Goas, Brazil. In October 2004, Brazilian ornithologist
Dante Buzzetti, following up on the report, heard a melodious song, and
using playback, brought in a male Cone-billed Tanager. The following
month, Buzzetti and Carlos filmed a pair of birds. Unlike published
illustrations (all based on the single museum specimen), in life the
bill of Cone-billed Tanager was strikingly pale, rather than black
[from World Birdwatch, 2006].
Emas
NP remains a consistent locale for Cone-billed Tanager. A fair number
of pairs are present in seasonally flooded gallery forest along the
Formosa River (habitat shown below). Marcelo found this male (left) by
song every day we visited the boardwalk there. The species has since
been discovered at Alto Rio Juruena, Mato Grosso, and several other
sites. Given these facts and its expanded known range, it seems likely
the bird will be moved to a less serious category in the future. For
the moment, though, it was a fine experience to photograph this rare
bird.
Despite the name, there is
serious doubt this bird is a tanager. A footnote to the SACC checklist
notes that "Storer (1960) suspected that Conothraupis was closely related to Sporophila based on remarkable plumage similarities; Zimmer (1947) had previously suspected that Conothraupis
was a "finch" and not a "tanager" based on bill shape." The pleasant
warbling song is finch-like, and our guide believed it was not a
tanager. It would not be surprising if genetic analysis (apparently not
yet done) showed it belonged to the Cardinalidae or Emberizidae. |

ENDANGERED |
CROWNED EAGLE
Harpyhaliaetus coronatus
This is the about the second largest eagle in the Neotropics (after Harpy; books vary as to whether Crested Eagle Morphnus guianensis
is larger) and perhaps the world's 7th or 8th largest eagle. Although
it has a wide range in the southern half of South America, we did not
anticipate seeing it on this trip because of its rarity. Birdlife
International says that it "qualifies as Endangered because it has a
very small, fragmented population, and the severity of the threats it
faces strongly suggest a significant and continuing decline in numbers.
"
We visited a remote valley in the eastern
portion of Emas NP which had thick cerrado forest of much greater
height than elsewhere in the park. We actually spotted three Crowned
Eagles flying away from us early in the morning, but views were poor.
Later, though, Marcelo spotted this perched subadult (above) that
eventually took off and soared right over us (right). Marcelo took a
lot of video of the eagle in flight and was more excited about this
bird than anything else we encountered during our trip. It was
interesting to see how much the pale head and blackish breast band
recalled the huge Harpy Eagle in pattern. The obvious black thigh
patches were not shown in any field guides we checked. |
HYACINTH MACAW
Anodorhynchus hyacinthinus
The
world's largest macaw is a spectacular component of the Pantanal
avifauna. Birdlife International says that "species qualifies as
Endangered because the population has undergone very rapid reductions
in the past and the threat from illegal trapping for the cagebird trade
plus habitat loss remains." Over 10,000 were taken from the wild in the
1980s. Today, though, it is seen as a tourist attraction in the
Pantanal, where it feeds mostly on the hard fruit of a few regionally
endemic palm species (Scheelea phalerata and Acrocomia aculeata).
Some pousadas are planting these palms, but nesting cavities remain
few. We did see Hyacinth Macaw daily in the Pantanal, including a nest
along the Rio Cuiaba. |
We also saw a male White-winged Nightjar Eleothreptus (Caprimulgus) candicans
by spotlight at night as it flew over the road outside Emas NP. The
male has extensively white wings and tail in flight, and is easily
identified; a small dark nightjar also spotlighted that night could
have been a female. Birdlife International says that "although the
species may well be found to occur at other sites, it is currently
known from just four locations, and it hence qualifies as Endangered."
The four sites are Emas NP in Brazil, two in Paraguay, and one in
Bolivia. Its habitat is dry cerrado. We saw the male flying from the
park to forage over corn fields to the south. |

VULNERABLE |
Lesser Nothura
Nothura minor
According
to Birdlife International, "rapid and extensive conversion of cerrado
grasslands is presumably causing a rapid population reduction in this
small tinamou. The population is now likely to be small and fragmented
over a large range, and the species therefore qualifies as Vulnerable."
We only saw one on our trip — this individual thinking of crossing the
road late in the afternoon at Emas NP (left). It stayed at the road
edge only briefly before running back into the grass.
|
Chestnut-bellied Guan
Penelope ochrogaster
It
was a surprise to find this on the list, and especially in the
Vulnerable category, because this is a comparatively common roadside
bird along the Transpantaneira through the Pantanal. Birdlife
International says that "species is listed as Vulnerable because its
small population and range are continuing to decrease owing to
continuing habitat loss, with additional pressures from hunting." While
it is "moderately common" in the vicinity of "Poconé, Mato
Grosso ... the extraordinary paucity of historical and recent records
suggests that elsewhere it is highly localized. Moreover, the
concentration of recent records suggests that it may have been
extirpated throughout much of its formerly large range." We did see
fewer this trip than during our 1999 visit.
Our best views in 2010 were of a family group feeding in flowering shrub along the Rio Claro (right). |
Black-fronted Piping-Guan
Pipile jacutinga
We
had one good-weather day out the Carmelo Road in Intervales NP, and
Edson found a pair of these gorgeous guans feeding on palm fruit in the
forest (male, left). We had another small group the next day in
drizzle.
This species is rated Vulnerable "owing
to the rapid and continuing reduction in numbers and habitat. Despite
once being abundant, extensive habitat loss and heavy hunting pressure
have extirpated the species from large parts of its former range and it
is now very rare outside a few protected areas." |
White-bearded Antshrike
Biatas nigropectus
"A
total dependence on one or few species of bamboo whose reproduction is
followed by massive die-off events, coupled with a substantial
reduction in suitable habitat, suggests that this species's current
population is small, fragmented and rapidly declining. It consequently
qualifies as Vulnerable," states Birdlife International.
We
found pairs on two days at Intervales State Park, where they worked
rather high in the canopy in mixed thickets of forest and bamboo. It
was very difficult to get any photos; this is a male (right). It was
very backlit and has been adjusted a lot in PhotoShop. |
Bare-throated Bellbird
Procnias nudicollis
Birdlife
International says that the "combination of increased rates of habitat
loss and more intense trapping pressures within this species's range in
Paraguay and Brazil mean that its population is likely to have been
undergoing rapid declines. For these reasons the species qualifies as
Vulnerable." It may now be mostly confined to protected areas in Brazil.
We
heard males calling from long distance on the sunny days in Intervales,
but the only one seen was this female at Itatiaia NP (left). It was a
cold, foggy, and drizzly day; the female bellbird was sitting
fluffed-out against the cold in a tree with small fruits. |
Sharp-tailed Grass-Tyrant
Culicivora caudacuta
"This
species qualifies as Vulnerable because it appears to be undergoing a
rapid decline owing to continuing habitat degradation and destruction.
Observations [have] demonstrated an apparent preference for older campo
cerrado habitats that had not experienced a spring burn and where Loudetia
grass species sprout up to ~2 m tall during the summer months. This
taller vegetation does not occur under an annual (or more frequent)
burn regime, as occurs at many cerrado localities. This lack of
availability of preferred habitat along with the frequent occurrence of
fires is a possible threat."
We found two small
colonies in grasslands at Emas NP where, given its preferred habitat,
it must still be considered common. Each colony was in patches of very
high grass and males were very vocal. This is a tiny flycatcher, but
appears very pugnacious for its size (right). |
Cock-tailed Tyrant
Alectrurus tricolor
This
striking small flycatcher is another denizen of extensive grassland
habitat. It was rather common in Emas NP, although patchy in
distribution, and males were just starting to molt into breeding
plumage. We did not see many with full 'cocked' tails. Yet they are
cute, as the males sit up high to look over their territories (left).
Birdlife
International says: "Extensive and continuing habitat loss throughout
the range of this species has presumably resulted in rapid population
declines. It consequently qualifies as Vulnerable. Grassland habitats
throughout its range are threatened by agricultural development,
livestock-farming, plantations and mining. Its dependence on tall
grasslands make it especially sensitive to intensive grazing, trampling
by cattle and frequent burning." |
Black-masked Finch
Coryphaspiza melanotis
"Extensive
habitat loss indicates that this species is likely to be declining
rapidly, and it consequently qualifies as Vulnerable. In Bolivia and
Brazil, it inhabits tall, sometimes seasonally wet, grasslands ...
There is evidence that it tolerates some grassland burning, at least if
the grass grows back to its full height," says Birdlife International.
We
saw only one of this very attractive species. I found it so
unexpectedly striking that it was in the running for making my "top
ten" highlights of the trip. I was very pleased that we had the
opportunity to get a photo (right) at Emas. |

NEAR–THREATENED
populations believed to have declined at a rate approaching the threshold for classification as Vulnerable |
Greater Rhea
Rhea americana
It
is not difficult to see a Rhea in the Pantanal or in Emas NP, but their
occurrence did seem rather patchy. They require large areas to survive,
including access to food and water. Most of the ones we saw around Emas
were actually outside the park because the park itself was very dry in
July. We found them most often grazing in corn or sugar cane stubble.
This
photo (right) was in the Pantanal, where the ground is gray so the
termite mounds are gray. In Emas, the termite mounds were brick red. |
Yellow-faced Parrot
Alipiopsitta xanthops
This
is a parrot of the cerrado. We saw it only at dawn or dusk along the
very dusty 25 km road from Chapado do Ceu to the south gate of Emas NP.
Here (left), two are feeding in a flowering tree in the warm early
morning light. |
Saffron Toucanet
Baillonius bailloni
This
is a strikingly lovely toucanet. During our brief visit to Itatiaia NP
we saw only a handful — likely due to the miserable weather — although
some did occasionally visit the feeders at Hotel Ype. It is an endemic
of the Atlantic coastal forests, of which only a small remnant is left.
|
Araucaria Tit-Spinetail
Leptashtenura setaria
This
small tit-spinetail lives among its namesake Araucaria trees (and is
shown atop one in this shot; left). These are odd conifers at high
elevations in the coastal mountains of eastern Brazil. We found only
one pair at 2000m in Itatiaia NP. |
Spotted Bamboowren
Psilorhamphus guttatus
Another
Atlantic forest endemic, the bamboowren was a taxonomic muddle for some
time. It has finally been sorted out that it belongs with the secretive
tapaculos. Its voice is quite distinctive, which I described in my
notes as a series of notes that "sound like a south pygmy-owl but with
N. Saw-whet Owl rhythm" — thus something like "too, too, too, too, too,
too ..." It lives in such a dense bamboo thicket that I described it as
"amazing" that I got any photo at all (thanks to Edson and his tape).
That was at Intervales SP (right). |
Slaty Bristlefront
Merulaxis ater
This
was another endemic tapaculo that I had much wanted to see. It is
exceptionally secretive — except when responding to Edson's tape! In
fact, Edson set his tape to play the call in a 'loop' and then set it
down under this little branch. The Bristlefront walked right out from
under cover, across the branch, and hopped on the tape-player!
Edson
Endrigo says that the Bristlefront photographed at Intervales (left)
has different vocalizations than the one present at Itatiaia, which we
also saw (but didn't manage a photo). There may be a split in this
species in the future.
|
Hooded Berryeater
Carpornis cucullatus
A
denizen of thick cloud forest in the Atlantic coastal mountains, we saw
only a very few in Intervales NP. This bird was responsive to the tape
but liked to sit in the most inconvenient places for photos — either
directly above us (right) or behind branches.
David
Snow's (1982) monograph The Cotinga stated that "Almost as little is
known about the berry-eaters' behavior as about their ecology. ... I
spent many hours watching Hooded Berryeaters ... in an attempt to find
out something about their behavior (but a 1871) old account proved
accurate as far as it went: 'the hollow and rather mournful note of
this bird is frequently the only sound one hears in passing through the
depth of the forest [but] the bird itself is not very easily noticed,
as it remains almost motionless on its perch." |
Black-and-gold Cotinga
Tijuca atra
This
attractive cotinga is a highland specialty in the Atlantic montane
forests. There males sit atop very tall trees and give their
distinctive calls. Edson used those to trick the owner, calling several
in from long distances away, for dramatic views (photo).
David Snow's (1982) monograph The Cotingas
quoted Ernest Holt's memorable account of his encounter: "I had been
long hours in the saddle. Now, amid lengthening shadows, I was
traversing the upper reaches of the forest zone ... Unexpectedly there
floated out upon the thin, clear air a vibrant note, a long-drawn
plaintive whistle that rose in pitch and intensity, and then faded away
in a mere thread of sound — withal so sad, so mournful, that it seemed
the cry of some languishing wood sprite rather than a vibration of
purely organic origin. With every sense alive, I craned my neck to see
the tallest tree tops.... but the notes died say, leaving on every hand
only silent green gloom. It was not until weeks after, when I trudged
those high trails day after day, that I stumbled by chance upon the
owner of that wonderful voice."
|
Gray-capped Tyrannulet
Phyllomyias griseocapilla
One
of a dozen small forest flycatchers in the Atlantic forests, this one
and three others that we saw [Sao Paulo Tyrannulet, Oustalet's
Tyrannulet, Serra do Mar Tyrannulet] are so range restricted as to be
classified as Near-Threatened. All were reasonably common at Intervales
NP (at least by the vocalizations, which were pointed out to us by
Edson Endrigo); Gray-capped was the only one of the set that was seen
at Itatiaia NP. They were a significant challenge to separate when not
calling and identified by Edson, but bill shape, behavior, and specific
habitat choice were helpful. Unlike the next species, which has
'wing-up' displays, this bird (right) is just taking off and I caught
its wing lifted in the half-second before it flew away.
|
Chapada Flycatcher
Suiriri islerorum
This interesting flycatcher is closely related to Suiriri Flycatcher S. suiriri, and the two were confused until recently. Chapada Flycatcher has a small range and is restricted entirely to cerrado habitat.
Both
Chapada and Suiriri Flycatchers live in pairs that often display
(especially when provoked by adjoining pairs or the tape), and their
plumage is very similar. We found both within a short stretch of road
in Emas NP. The Chapada Flycatcher differs in having a shorter bill, a
pale terminal tail band, and in its displays — birds lift their wings
up high above their head in this fascinating species (left). |
Brown Tanager
Orchesticus abeillei
This
Atlantic forest endemic was found daily in Intervales NP. Sometime
single birds would be foraging in shrubbery around our lodging, and at
other times we would see a half-dozen in a mixed canopy flock (right).
Often those flocks would contain two other rufous-colored species:
Chestnut-crowned Becard Pachyramphus castaneus and Buff-fronted Foliage-gleaner Philydor rufum. |
White-banded Tanager
Neothraupis fasciata
This
tanager with a boring name reminded me of Loggerhead Shrike each time I
saw it. It is a bird of cerrado and grasslands, and we saw a fair
number in Emas NP which has preserved this rapidly declining habitat
(left). |
Azure-shouldered Tanager
Thraupis cyanoptera
One
of a plethora of colorful tanagers that came to a makeshift feeder
hosting bread and bananas at Intervales NP, I don't recall ever seeing
it away from that feeder. It is clearly related to Blue-gray Tanager
(which does not occur in southeast Brazil) and Sayaca Tanager (which
does, and which also came to feeders there), but Azure-shouldered is
brighter and has dusky lores. |
I saw but did not photograph Mantled Hawk Leucopternis polionotus, Rufous-tailed Antbird Drymophila genei, Cinnamon-vented Piha Lipaugus lanioides, Sao Paulo Tyrannulet Phylloscartes paulista, Oustalet's Tyrannulet Phylloscartes oustaleti, Serra do Mar Tyrannulet Phylloscartes difficilis, Forest Elaenia Myiopagis gaimardii, and Black-legged Dacnis Dacnis nigripes. All of them are placed in the Near-Threatened category. |
