Water, and the way it interacts with other materials, can be fascinating. Take the water droplets on this feather, for example.
Considering there weren’t any droplets on the surrounding dirt or grass, I’m not exactly sure why the water is clinging to the feather in this way. Presumably it has something to do with the structure of the feather itself, the miniscule hooks and barbs that hold the feather together and help to keep a bird waterproof. It certainly was lovely to look at.
