Swans
Admittedly, swans are described as the easiest to reach. Swans are used to humans, so they can be approached quite easily.
When photographing all animals, of course, it must be remembered that nesting, for example, must not be disturbed by too intrusive behavior. A sufficiently long objective must be found in the equipment. Swans are associated with the concept of loyalty, so when photographed, romantic images are created. The photographer can feel successful in getting a picture of a heart shape made up of swan necks.
