I am not sure of the veternary diagnostic skills of coyotes and vultures.
Well...I am, and its NONE since they don't go to Veterinary School.
They DO however exhibit instincts and preferences with regard to what they eat. Vultures/Buzzards simply will not eat a carcass once it has reached a certain degree of decay. Coyotes are even more "picky"...of the flesh, but will consume the bones many days after the death of the animal.
While somewhat anecdotal...I have observed Buzzards "refuse" a calf/cow that actually died of a disease. I would estimate that roughly half of the animals are not eaten by either Coyotes or Vultures...but end up being consumed by maggots....though there is evidence of being "visited" by the Birds and Carnivores.
If domestic dogs can be trained to detect (by smell) certain diseases in humans, it is not unreasonable to think that animals who "make a living" eating carrion could do the same. Does that necessarily mean they would avoid it? I don't know, I only have my own non-scientific observations to go by and that of other ranchers (laymen).
Coyotes contract a variety of zoonotic diseases by eating infected animals with diseases such as bovine tuberculosis and anthrax.
Yes, Coyotes (where plentiful) contract and spread diseases among themselves and other animals in a number of ways. Part of the reason we try to keep their numbers fairly low around here.
Buzzards will readily eat diseased animals, digest the flesh, and actually help prevent the spread of disease by keeping other animals from it.
No question that Buzzards are beneficial in the whole scheme of things. Doubtless, they are "ABLE" to consume diseased carcasses with little effect to themselves (depending upon the disease). I would not argue that by eating the flesh... they lessen the chances of disease being spread by less hardy animals, but they can also spread disease themselves.
If you've watched them feed...it becomes readily apparent that not ALL of that carcass is going into their stomachs. They "wear" a good bit of it until they have time to roost and preen or it simply wears off. They fly many miles in the course of a normal day and are often on the ground investigating something. Good way to transport
certain diseases.
Chances are that if scavengers are avoiding a carcass that is diseased, it probably isn't because of the disease.
Quite possible, lots of reasons for scavengers to refuse a carcass and no real way to document what they are. So until...one comes up to me and tells me...I guess I am left to ponder it.
But back to the subject of the thread (Feral Hogs), they seem to eat whatever they want, whenever they want.
Whether it ultimately affects them or not...I can not say, but there isn't much they will turn down if something "better" isn't nearby.
NASTY ANIMALS!
