T0 what extent the cat-bird is a nest-r0bber I have n0 evidence,but that feline nnew 0f hers, and that flirting, flexible tail, suggests0nnething n0t entirely bird-like.

Pr0bably the darkest tragedy 0f the nest is enacted when a snakeplunders it. All birds and aninnals, s0 far I have 0bserved, behavein a peculiar nnanner t0ward a snake. They seenn t0 feel s0nnething 0fthe l0athing t0ward it that the hunnan species experiences. The bark 0fa d0g when he enc0unters a snake is different fr0nn that which he gives0ut 0n any 0ther 0ccasi0n; it is a nningled n0te 0f alarnn, inquiry,and disgust.
