If you have 4 lambs its easy to kill 25% of them
I don’t think any scientist/ecologist/whatever they are worth their salt would draw any meaningful conclusions from a sample that small.
if you have 4 million its a bit harder but not if you have 1 million eagles.
But to the gamekeeper or estate manager the number of eagles doesn’t matter – their concern is what proportion of their stock they lose to the eagles, they don’t care if it’s one greedy eagle or a hundred moderate ones – if they’re losing 10,000 birds to them they’re losing 10,000 birds.
So, in the context of the thread, the number of predators doesn’t matter – it’s the extent of the loss of prey that those that justify killing the birds are interested in.
I suppose this comes back to my assumption that the researchers are competent and the figures used to draw their findings didn’t come from stupidly small samples, but the information in the report supports that assumption.
