They are called Nature’s scavengers. They eat putrid flesh and thus prevent many diseases. But the carcasses they used to clean had done them in since a few years back. The cattles were given declofenac , a medicine for fever and even if a fraction was retained in the flesh of animal, its flesh was like a poison for the vultures. So their number began dwindling, so much so that they became endangered species.
In India, i remember of my childhood village days, there was a place outside every village where dead cattle were thrown. Vultures would descend on it and eat the flesh. They made peculiar sounds. They are so big that even dogs wont dare go near. Only crows are allowed the liberty.
All this is gone now. But a few days back, i happen to spot vultures outside a village where a carcass was thrown by some villager. After so many years saw and heard the voices.
There were Himalayan Griffon and Cinereous vultures…
