At the end of the day, most birds try to perch (they are thus better protected against predators). In an area with a high animal density like Botswana, it allows some interesting encounters like this juvenile grey heron and these three openbill storks.
As can be well seen in this picture, the name of the storks comes directly from their bill which cannot close hermetically and which allows them to break shells where they find most of their food intake (a bit like a nut cracker).
