This photo of cormorants sitting in a tree was taken at the Florida Everglades. These birds eat small to medium sized fish which they catch by swimming under the surface of the water. They are amazing swimmers; under water they propel themselves with their feet with help from their wings; some have been found to dive as deep as 150 ft.
Both cormorants and anhingas (another underwater swimmer) can be seen drying their wings out in the sun because their feathers get waterlogged and make it difficult to fly. I remember the first time I saw a bird (probably an anhinga) sitting in a tree with its wings outstretched. It struck me as almost bizarre, because I did not know it why it was doing so.
The same thing happen with human behavior. We view the actions of others as bizarre or inappropriate. Often we don’t know a thing about them or their background.
