Endangered cuckoo spotted in Indonesia
Mon Jul 10, 8:18 PM ET

JAKARTA, Indonesia - Scientists trying to photograph wild tigers deep in the Indonesian jungle captured a glimpse of another endangered species instead ? the Sumatran ground cuckoo.

An Indonesian-British surveying team released rare images of the short, brown fowl, with black and green plumes, taken with a sensor-triggered, camera.

The bird, apparently startled by the flash, is seen gazing into the lens with spread wings.
"Finding the Sumatran ground cuckoo gives me hope, because it was photographed in disturbed forest that has been left to recover near the national park," said Dr. Matthew Linkie of the University of Kent in England.


The July spotting, near Kerinci Seblat National Park in central-west Sumarta, was the third known recording of the bird since 1916, a statement said. The bird's scientific name is Carpococcyx viridis.

"We've photographed rhinoceros hornbills and great argus pheasants before but when we found that we'd photographed a Sumatran ground cuckoo, we couldn't believe it," said field leader Yoan Dinata of Fauna & Flora International Indonesia.

The Sumatran rain forests contain some of the world's richest biodiversity but they are also among the world's most threatened forests, due mainly to illegal logging.

Extinction fear for black rhino

The West African black rhino appears to have become extinct, according to the World Conservation Union (IUCN).

A mission to their last known habitat in northern Cameroon failed to find any rhinos or signs of their existence.

The sub-species has declined in recent decades due primarily to poaching, which has also brought the northern white rhino close to extinction.

In East and Southern Africa, numbers of related sub-species are rising with the use of effective protection measures.

But after two decades of warnings, the western black rhino has apparently met its final end, according to the findings of an extensive expedition by three specialists earlier this year.

"They mounted 48 field missions, patrolling for 2,500km, working block by block," said Richard Emslie, scientific officer with the African rhino group in IUCN's Species Survival Commission.

"They looked for spoor, they looked for the rhino's characteristic way of feeding which has an effect like a pruning shear, but they didn't find anything to indicate a continued presence in the area," he told the BBC News website.

"They did, however, come across lots of evidence of poaching, and that's the disconcerting thing."
Bleak prospects


Even before this latest survey, prospects for the sub-species appeared bleak.

In 2002, numbers were as low as 10. The animals were distributed over a wide range, making breeding more difficult.

"With small numbers, bad luck can play a much bigger role - if you just have male calves, for instance," commented Dr Emslie.

During the last 150 years, numbers of all types of rhino plummeted in all regions of Africa.

The southern white rhino reached its nadir in 1895, with a single population down to about 30 individuals in one South African game park.

Since then, captive breeding and successful protection measures have brought numbers up to nearly 15,000, and groups have been re-established in other countries.

The black rhino's decline came later. The continent-wide population numbered about 100,000 in 1900, but fell to a low point of 2,400 by 1995.

Again, protection measures and breeding programmes are bringing stocks back up, but only, so far, to about 3,600.

The main successes have been in Southern Africa, with some East African countries also re-introducing and maintaining populations.

It is a different story in West Africa, where poaching, often fuelled by the guns and poverty of civil conflict, has been harder to control.

The northern white rhino is down to as low as four individuals in its only remaining habitat in the Democratic Republic of Congo; and now the West African black rhino has apparently vanished entirely.

Although genetically distinct, the different sub-species may be similar enough in their food and habitat requirements that animals could be re-introduced to West Africa from other parts of the continent.

But that would require stable political and economic conditions, the resources to take on poachers, and the commitment to involve local people in the animals' conservation.

Even if this were possible at some unspecified time in Cameroon, it appears that one of Africa's great wildlife icons has now lost a valuable branch of its family.

AFRICA'S RHINOS
Southern white (Ceratotherium simum simum) - 14,500 and rising
Northern white (Ceratotherium simum cottoni) - only four may remain
South-central black (Diceros bicornis minor) - 1,900 and rising
South-western black (Diceros bicornis bicornis) - 1,200 and rising
Eastern black (Diceros bicornis michaeli) - 650 and rising
Western black (Diceros bicornis longipes) - feared extinct
