Allan Octavian Hume,
The Nests and Eggs of Indian Birds…
“ Built on a rock in the midst of a roaring torrent, not the smallest attempt at concealment is made; the nest lies open to the gaze of every living thing, and the materials are not even so chosen as to harmonize with the colour of the site. But if an easily accessible sloping mossy bank, ever bejewelled with the spray of some little cascade, be the spot selected, the nest is so worked into and coated with moss as to be absolutely invisible if looked at from below, and the place is usually so chosen that it cannot well be looked at, at all closely, from above. ”
