Very common birds are often quite clever. Look at ravens and crows. They can use simple tools to get what they want, which is often food, but we know that nests may also include watches, spoons and jewelry.
It is worthwhile to look at birds from a distance, to see them at their own free will, not manipulated by food placed by humans and not at their nests. I mean, how fun is it to photograph people eating or people outside their home? I guess it depends … but most often, it is more fun to see an animal having fun or just resting somewhere.
