yea on the tree not off
You can leave your oranges on the tree till you use them. Commercial growers leave Valencia oranges on the tree for a full year. I find those left on the tree a full year to be the largest and sweetest. When the oranges are done they will shrivel up and drop off. So leave them on the tree till you need them. That way they stay fresh and continue getting sweeter. It is natures way of storage. Enjoy.

I'm afraid there is no straightforward answer to this. There are many varieties of oranges and they all ripen during certain times of the year. So you could have a constant supply of oranges if you had enough trees.
by simply plucking it
Oranges.
There is often a change in supply and demand of oranges.
Bats do not 'take off' they cannot do that. They just drop from the tree and spread their wings. That is why they hang upside-down.
