New Bird

Some details here on the Togian white-eye and its discoverer. And a quote of interest:

"Joel Cracraft, the curator in charge of the Department of Ornithology at the American Museum of Natural History in New York, said there's a popular perception that most bird species are widespread, that, like the American robin, they inhabit huge ranges.
"'But, in fact, most birds, most organisms are very narrowly distributed,' he said. 'They're found only in small areas and nowhere else in the world. When you have a situation like that, then you are likely to discover new species.'
"And, he added, 'There's just so much on this planet that hasn't really been investigated scientifically, lots of areas in the Andes, in Himalayas, in southeast Asia, in the big, big rainforest areas of South America and Congo.
"'We have not truly explored this earth, in terms of all the life forms that are on it. We are nowhere near complete in that effort.'"

Ethnoknowns from the Philippines

There's a report of species newly recorded from Mindanao island, which includes two folkloric accounts of animals that may or may not be recognized species (and may or may not be something as yet undescribed). The first is a "red-faced monkey":

"
A group of red-faced monkeys that can mimic human laughter has been sighted in the mountain ranges of Sal-dab, a sacred mountain in Northern Mindanao, The STAR learned recently.
"The monkey that mimics human voice is known to natives as Uma-ay and is believed to bring a curse on whoever sees it.

"According to local folklore, whoever sees the creature will lose his way in the jungle or may encounter misfortune, accident or even death along the way." ...
"
A tribal trapper interviewed by The STAR last year said the Uma-ay looks human because they do not have hair on their faces and can mimic the human voice. They grow up to the size of the native monkeys in the area.
"'The laugh of an Uma-ay is an ominous sign, it means misfortune or even death,' the tribal hunter said in the Hiliga-onon dialect.

"The hunter declined to name the location of the place where the Uma-ay can be found but said it is sacred ground where tribal elders offer sacrifices and perform yearly rituals to appease their gods."

Now, Mindanao has one recognized monkey species, the common crab-eating macaque. That species isn't known for a bright red face (though that trait is known in the related Japanese macaque). So, might these red-faced monkeys be something new? A variant of the recognized macaque species? Or just a bit of local folklore? Another ethnoknown is briefly noted:

"
Aside from the Uma-ay, the tribal folk also mentioned that they sighted an unnamed feathered bird that has mammal’s hair.
"Just like the Uma-ay, the bird also mimics the human voice but its favorite sound is the cry of a newborn baby.

"The natives call the creature Ukang (owl) or gulus (ghost). This nocturnal bird is often heard making noise at night but only a few elders have actually seen it.

"Tribe members believe that the Uma-ay mimics the human voice to drive away the Kalumbata (monkey-eating eagle), which regularly hover in the area in search for food.

"It is said that Uma-ays would simultaneously sound their laughter to confuse the marauding eagles."

Not enough details, and most of this might be superstition masking the description. Whenever you have strange nocturnal calls, there's a potential for mistaking the identity. (News source.)

It also mistakenly says the vulture was previously considered extinct worldwide, but that appears to be incorrect. As BirdLife notes, the species has suffered catastrophic decline in Pakistan and India, but is still known to exist in some flocks there. And, there are populations elsewhere, though it is considered critically endangered.

Brazilian Antwren

BirdLife has announed a possible new species of antwren from Bahia, Brazil. The species, the Sincorá Antwren (Formicivora grantsaui), was described in:

L. P. Gonzaga, A. M. P. Carvalhaes, & D. R. C. Buzzetti. 2007. A new species of Formicivora antwren from the Chapada Diamantina, eastern Brazil (Aves: Passeriformes: Thamnophilidae). Zootaxa 1473: 25–44

The bird "is found only in the campo rupestre vegetation of the Serra do Sincorá between 850 m and 1,100 m in the Chapada Diamantina region. This is an important area that holds other restricted range species such as Grey-backed Tachuri Polystictus superciliaris and Pale-throated Pampa-finch Embernagra longicauda. First observed in 1997, it is closely related to Rusty-backed Antwren Formicivora rufa, with which it sometimes occurs sympatrically. It differs slightly in some plumage characters but more importantly it has quite distinctive vocalisations and each species utilises different habitats. Formicivora grantsaui occurs on rocky outcrops in the campo rupestre and F. rufa in the adjacent savannas."

Cowbird Mafia

Turns out cowbirds weren't merely duping the host birds into taking care of their eggs and offspring; it was blackmail, pure and simple. National Geographic News notes:

"Cowbird mothers keep watch on the nests where they've laid their eggs.
"If the birds find that their eggs have been destroyed or removed from the nest, the cowbirds retaliate, the study says.
"The birds reportedly destroy the host birds' eggs, pecking holes in them or carrying them out of the nest and dropping them on the ground."


Not all ornithologists are convinced by this new study, as the cowbirds' deprivations weren't caught in the act, but the proponents say they have ruled out all other possibilities.

Rare Cuckoo Recorded

A large bird from Sumatra, rediscovered only in the last decade, has finally been recorded on audio tape, which should help ornithologists survey the rare species. From Eurekalert:

"A team of biologists with the New York-based Wildlife Conservation Society (WCS) have recorded for the first time the call of the extremely rare Sumatran ground cuckoo, found only on the island of Sumatra in Indonesia.
"The bird was captured by a trapper and handed over to WCS biologists, who recorded the bird’s call while it nursed an injured foot. Once fully recovered, the bird will be released back into the wild.
"Known only by a handful of specimens collected over the past century, the Sumatran ground cuckoo is considered to be one of the world’s rarest, most secretive birds, and is restricted to Sumatra’s deep jungles and rainforests. In fact, ornithologists believed the bird was extinct until 1997, when a single individual was briefly seen. Last year a second bird was photographed by a remote camera trap. It is now believed to be critically endangered. Until now, however, no one knew the bird’s call – a key field diagnostic ornithologists use to identify birds that live in forest. According to WCS, having a recording of the bird’s call will also make it easier for biologists to locate other individuals, and to possibly evaluate the bird’s total population.
"'We were extremely lucky to have recorded the bird’s unique call,' said Firdaus Rahman, of WCS’s Indonesia Program. 'Our team will use the recording to hopefully locate other Sumatran ground cuckoos, and to eventually secure their protection.'
"The recoded call can best be described as a pair of sharp screams. It is unknown at this point whether the bird has additional vocalizations.
"Sumatran ground cuckoos are relatively large birds (half a meter long) with long tails. It has green plumage with a black crown and green bill, and striking blue facial markings."

New Parrot or Fake Photos?

Following news reports of the possible discovery of a blue-browed fig-parrot in Queensland, comes a report that the photos have elements that suggest alteration. From the Australian:

"The reported discovery of a new species of parrot in Queensland's rainforests has been undermined by a leading authority on forensic photography.
"The Beattie Government has dissociated itself from naturalist John Young after Gale Spring, associate professor in scientific photography at Melbourne's RMIT University, cast doubt on a photograph of a parrot Mr Young claimed was new to science." ...
"In November, Mr Young's company, John Young Wildlife Enterprises, and Queensland Environment Minister Lindy Nelson-Carr announced the discovery of the so-called blue-browed fig-parrot in the rainforests of southern Queensland.
"Mr Young and the Queensland Government's endangered species officer, Ian Gynther, were to publish a scientific article about the discovery.
"The photograph of the parrot was featured prominently in Brisbane's Courier Mail newspaper. At the time, The Australian reported Mr Young had made similar claims in the mid-1990s which were not substantiated, and that there were doubts about the photograph. The bird depicted closely resembled the red-browed fig-parrot of north Queensland, except the forehead was blue, not red. Soon afterwards, Professor Spring was sent a high-resolution image of the photograph.
"At a briefing in Brisbane last week, Professor Spring showed computer images of the photo to Dr Gynther and other Environment Department officers. He pointed out differences between the texture of feathers around the bird's head and feathers on the rest of its body. He thought the surface imaging of the photograph was typical of pictures that had been altered, and although there might be an explanation for this, said he needed to view the original image.
"He offered to examine the original photographs on a CD or under supervision at Mr Young's Brisbane office. The inspection would have resolved the matter, but the offer was not taken up.
"'Without seeing the original images, it is not possible for me to conclude absolutely this photograph is not genuine,' Professor Spring said. 'Nonetheless, I have doubts about several aspects, and this clearly requires inquiry.'"
