Birds become shy where persecuted, and the young, even when not disturbed, learn a shy habit from the parents, and from other adults they associate with. I have found small birds shyer in desert places, where the human form was altogether strange to them, than in thickly-settled districts. Large birds are actually shyer than the small ones, although, to the civilized or shooting man they seem astonishingly tame where they have never been fired at. I have frequently walked quite openly to within twenty-five or thirty yards of a flock of flamingoes without alarming them. This, however, was when they were in the water, or on the opposite side of a stream. Having no experience of guns, they fancied themselves secure as long as a strip of water separated them from the approaching object. When standing on dry land they would not allow so near an approach. Sparrows in England aro very much tamer than the sparrows I have observed in desert places, where they seldom see a human being.
