Bolivian authorities are investigating the deaths of 35 rare Andean hawks in a rural area southwest of Tarija province.
“This loss is extremely serious for nature,” said biologist Diego Mendez. “Birds that died in Tarijia on 2/7 may represent 0.5% of the species’ population.”
The Andes, or ancient vulture (Vultur gryphus), are currently classified by the International Union for Conservation of Nature as “near threatened” with a population of only around 6,700 worldwide. They are one of the largest raptors when they can grow up to 1.3 meters in length and have a wingspan of up to 3.5 meters.
Initial investigation revealed the animals died of poisoning, possibly a few days ago, but the motive remains unclear. The culprit may have targeted birds or attempted to poison other animals, but accidentally killed the eagle because they were scavengers.
