Free-ranging dogs threaten wintering vultures at Bikaner carcass dumpsite, study warns

UPDATE - follow-up to Feral dogs 'a major threat' to vultures in Thar desert, study finds: Free-ranging dogs pose a serious threat to endangered migratory vultures by directly competing with them for food at livestock carcass dumpsites in Rajasthan's Thar desert.

Feeding Disruptions

A study published in the journal Biological Conservation reveals that vultures spend about half as long feeding on carcasses at the open Bikaner dumpsite in the Jorbeer Conservation Reserve compared to dog-free enclosures. The presence of dogs also changes when birds eat, pushing vulture activity mostly into the afternoon instead of spreading it evenly across daylight hours. According to co-author Abi T. Vanak of the Ashoka Trust for Research in Ecology and the Environment, setting up dog-proof feeding sites and managed vulture safe zones can help the birds forage without interference.

Context

Traditional livestock carcass dumps in India serve as accidental feeding spots for scavenging birds, unlike the managed safe-food stations found in Europe and Africa. Managing these garbage and carcass sites remains vital for wildlife conservation as bird populations struggle to recover.
