Bird of the Day August 13, 2013: White-rumped Vulture in Ahmedabad, India photographed by Srinivasa Addepalli
Vultures are very important members of many ecosystems in the world as members of a waste-management team, but their role as carrion-feeders is putting them at risk, and has been since the California Condor was endangered in the US (though it’s recovering now). We’ve featured these birds in our daily photo posts quite a bit, even just a week ago, and now there’s news from Scientific American, covering research published in the Journal of Applied Ecology, that European vultures are more threatened than ever, this time by a veterinary drug given to cattle:
A veterinary drug blamed for driving vultures to the brink of extinction on the Indian subcontinent could cause thousands of bird deaths now that it is being used in Spain.
Researchers have expressed concern over use of the anti-inflammatory drug diclofenac in cattle since it was approved for veterinary use in Spain in 2013, as the drug is toxic to vultures who may consume it via dead cows. Now, modelling by Rhys Green, a conservation scientist at the University of Cambridge, UK, and his colleagues suggests that the drug could cause populations of that country’s Eurasian griffon vultures (Gyps fulvus) to decline by between 1–8% each year.


















We are susceptible to stories that spotlight animal intelligence, and challenge our assumptions about the unique capacities of humans. Cleverness and intelligence can be difficult to parse, so the details of the story matters.
