African black herons have a very unique hunting technique – they use their wings to form an umbrella, which not only reduces glare but also makes their prey, the fish, feel safe. fake.

Known as “predation,” the hunting technique used by black herons is one of the most stealthy observation techniques in nature. The black bird walked slowly through the shallow water and then spread its wings around its body, forming an umbrella that blocked the light. Although it’s not entirely clear why African herons use this particular technique, scientists hypothesize that it has several advantages, such as reducing glare and attracting fish into the trap.

A widely accepted theory is that small fish, seeking refuge from predators such as the African black heron, are attracted to the shade cast by the heron’s wings and plummet towards their deaths. yourself to find safety. And because the shade helps the bird see its victim more clearly, it can easily snatch it out of the water with its long beak.

“ It’s all part of herons’ hunting tactics, which spend a lot of time looking for specific prey,” Bill Shields, a professor at the SUNY College of Environmental Science and Forestry, told Audubon. . small just below the surface of the water.”

Interestingly, African herons have bright yellow legs, which may be used to annoy and distract targets, the way other herons do, but the “screen feeding” technique “che” proved so effective that birds evolved to rely almost exclusively on it.

“ It could also be argued that the attraction of both shad and light legs work together to attract fish into striking range, ” Evans said.
