Selected sequences
Black heron tricking fish into shade
The bird make shade that fish are fooled into believing to be made from plants and swim into the shade (left), only to be stabbed by the bird (right, 10’35-11’37). The companion book (p. 123) has some even more interesting material on a related species – green backed heron in Japan – where it learnt from people feeding the fish and started doing the same thing. It picked up edible things that the fish would eat but the fish would. It took those to the lake and flicked it onto the surface. When the fish came to take it the heron would take the fish. Similar stories can be found for birds, mainly herons, from around the world (Bird bait-fishing). A similar sequence was included in the Life on Earth series too.
