When the annual flood recedes in the Okavango Delta, the birdlife takes full advantage of the fish stranded in ever-shrinking pools. This egret in particular has a fascinating fishing method that’s very effective, and always fun to watch.
The bird strolls purposefully into the water and then suddenly unfolds its wings to form an umbrella-like “shade” which takes away the glare, much like a pair of polarized sunglasses. This allows the egret to see into the water and catch the unsuspecting fish within the circle of shade.
One theory is that it also confuses the fish into thinking that there is some form of cover to hide under. These egrets have bright yellow toes which they are thought to “wiggle” in the mud, which in turn, attracts small fish. Whichever theory is correct, it is great fun watching a group of these birds fishing, as it gives the appearance of a bunch of small black umbrellas covering the water.
