As regular CFZ-watchers will know, for some time Corinna has been doing a column for Animals & Men and a regular segment on On The Track... particularly about out-of-place birds and rare vagrants. There seem to be more and more bird stories from all over the world hitting the news these days so, to make room for them all - and to give them all equal and worthy coverage - she has set up this new blog to cover all things feathery and Fortean.

Over 500 Rare Vultures Die After Eating Poisoned Elephants In Botswana



A total of 537 vultures, along with two tawny eagles, were found dead at the site in the north of the African country.

GABORONE, BOTSWANA: 
More than 500 endangered vultures died of poisoning after eating the carcasses of three elephants killed by poachers in Botswana, the government said in a statement.
A total of 537 vultures, along with two tawny eagles, were found dead at the site in the north of the African country.
The Botswanan wildlife and national parks department did not say when the dead vultures had been found or why the three elephants were laced with poison after being killed.
But poachers are known to poison carcasses to target vultures as the birds circle in the sky and help rangers to track poaching activity.
Most of the birds, 468 of them, were white-backed vultures, which are classified as critically endangered on the International Union for Conservation of Nature red list of threatened species.
Also among the dead were 17 white-headed vultures and 28 hooded vultures -- also critically endangered.
"The poisoning was believed to have been caused by lacing of three poached elephant carcasses with a poisonous chemical," the wildlife department said.
Teams decontaminated the area and samples were taken for laboratory analysis.
Conservationists last week warned of surging elephant poaching in parts of Botswana and estimated nearly 400 were killed for their ivory tusks in 2017 and 2018.
The country recently sparked controversy by lifting its ban on hunting, saying it would help control a booming elephant population that was damaging farmers' livelihoods.

In 2016, two lions and over 100 vultures in South Africa's Kruger National Park died after eating a poisoned elephant carcass.

Botswana raptor declines shock researchers


09/06/2018

A two-year project, repeating a famous bird survey by driving more than 12,500 miles across Botswana, has confirmed researchers' worst fears: many birds of prey are fast disappearing from one of Africa's last great wilderness areas

Reported sightings of several iconic species of eagle and vulture declined by as much as 80 per cent when compared with the previous survey, while some migrant species recorded last time have vanished, according to the study published this week in the international scientific journal Biological Conservation.

The data is based on a return trip to a network of roads criss-crossing most of northern Botswana, an area first surveyed over 20 years ago by a former Wildlife Biologist with the Department of Wildlife and National Parks Botswana, Dr Marc Herremans. Driving at similar speeds and using a similar vehicle, researchers retraced Herremans's route across gravel and tar roads. Bird of prey were initially spotted with the naked eye, before optics were used to positively identify the species involved, as in the original survey.

Big game hunters in Africa urged to drop the lead to help save vultures



Lead bullet fragments in carcasses left by hunters are poisoning endangered African vultures, a new study has found

A third of all vultures caught and tested in the Botswana study showed elevated levels of lead in their blood, most likely due to ingesting lead bullet-contaminated flesh. Hunters' bullets shatter inside their prey and can then be absorbed into the blood stream of the vultures when they feed on these animals or their remains. This ingested lead is highly toxic to birds.

"We were all shocked by how widespread lead poisoning was for this population and just how clearly these elevated levels were associated with recreational hunting activity," said Dr Arjun Amar, Associate Professor from the University of Cape Town's FitzPatrick Institute of African Ornithology, who supervised the research.

The study, published this week in the international journal Science of the Total Environment, is based on tests of nearly 600 critically endangered African White-backed Vultures. Higher lead levels were found in the blood of vultures in the hunting season and in hunting areas, suggesting that the source of the lead in their blood stream was lead bullets used for hunting.

"The only logical explanation for the patterns of lead poisoning we observed is if lead bullets were the source of this contamination" said the study's lead author Beckie Garbett, who conducted the research as part of her PhD.
