A rhombus is a shape that resembles a diamond. Opposite sides are parallel and of equal length. So, is this a rhombus? The sun casts the shadow of the broken twig at such an angle that it appears to be a rhombus. If the sun were directly above, then the shadow would be cast down and not appear to be a rhombus. If the sun were setting, then the shadow would be longer and not appear to be a rhombus. Likewise, if I moved left or right or up or down, the image might "keystone" and no longer appear to be a rhombus. It was the unique combination of factors which led to the illusion of a rhombus, which itself is not real, but an attempt to describe objects in time and space.
The green heron uses bait to fish. I have long decided that our fellow animals are much smarter than we used to believe. When I was young, I was told that use of tools was one of the main things that differentiated us from our fellow animals. But it turns out that many animals use tools. What differentiates us from our fellow animals is that we have developed speech centers in our brains, which allows us to pass on our knowledge and to use Twitter to criticize people we don't like. Another issue is whether our fellow animals are getting smarter. Most articles I read say that it is not so much that they're getting smarter, but that they're able to learn and adapt to new situations much in the same way humans do.
