They are wild, as nature intended, and we should allow them to remain so.
I agree - and if it sounded like I was anthropomorphizing, I didn't mean it to sound that way. Whatever is their hardwiring, there are behavioural milestores that even we poor humans are recognizeable as they develop. For humans, babies under a certain age have no fall-from-height reflex (no idea what its called) hence the baby gates on stairways. At a certain point in their development, the reflex kicks in and their whole mode of movement changes. It's a hardwired mental change but is it also an emotional change.
Outside my sphere of expertise, but it's what makes observing such a great way to spend some time.
no fall-from-height reflex is called depth perception. This is one reason that few dogs are able to watch tv and recognize what is going on. Most dogs do not have this depth perception ability when it comes to tv but when it comes to other things like playing fetch they know. (This is according to a vet. We had one dog that had depth perception and would watch the tv shows with us). I am assuming that when the falcon chicks get their depth perception, they will also soon fledge. We know that two do have some because they are able to get up on the ledge. The other two will soon develop their depth perception ability. Until they fledge, they will wingersize to build up strength and then one day they will see their parent flying overhead and jump to join them.
As humans, we understand ourselves in descriptive terms and we assign these descriptions to other things living and/or dead in our attempt to understand them too.
