So you won't pee if there is no place to pee.
Explain it to me how you can't pee if there is no specific place for it.
How that is comparable to nesting which is a must for the birds in order to survive.
Can you not read?
I didn't say that at all.
I said that you made a poor example.
If you have to pee, you WILL pee. It's just a matter of where it is.
You may pee your pants, in a bush, or in a toilet.
The fact of the matter is: you WILL pee.
The same thing applies to nesting.
Obviously, it's now instinct and is taught because it's been done for so long and it works...
But there didn't HAVE to be a teacher. Trial and error.
A bird is smart enough to figure out that laying eggs (and leaving them) directly on the ground doesn't work most of the time.
So, they may have tried laying them in grass.
Then, they could have piled up the grass.
Before you know it, we have nests.
The point is...there doesn't have to be a teacher for ANYTHING.
That goes for humans, animals, anything.
