What does "bird hunting" in photography mean?

Hello, the so-called "bird shooting" in photography is the so-called shooting of objects, such as birds, distant animals, the moon and so on, with SLR cameras and ultra-long focal length lenses. You can shoot very clearly with an ultra-long focal length lens. The ultra-long lens with key energy EF- 10-600 is suitable for shooting distant objects. The lens can be telescopic and can zoom in on distant objects for shooting. For example, a full-frame camera can use a long lens and shoot with autofocus technology, and the shooting effect is better. This is what photographers call "shooting birds".
