Reginald Badham Lodge, The Zoologist (1901)
“ Not only birds at their nest, but any bird or animal, large or small, diurnal or nocturnal, which can be attracted by a bait, or which habitually uses the same path or run, can now be photographed. Of course, for nocturnal animals the inclusion in the circuit of a flash-light, to be ignited by the same current which operates on the shutter, is indispensable. Besides the Purple Heron, the trap was tried at the nests of a Marsh-Harrier and a Great Crested Grebe. ”
