This does not add up. Natural selection has been described as "mindless" and "blind", yet if a bird is doing the selecting (a bird is not blind or mindless). And if the selection factor is not a living one such as what? Firstly how can we define "non living" , I personally don't see anything as non living buts thats a whole different debate over the meaning of life... so you must mean "abiotic" factors such as weather, so if the selection factor is weather then how can natural selection then not be random? remember natural selection has been described as "non-random" and "directed" so there has to be a conscious agent behind it, so the weather has a mind and can select? How can anything at all in nature be "selected" if it is "mindless"?
