The whole of this old saying is "A bird in the hand is worth two in the bush"
A bird in the hand is a sure thing; it’s in your hand. You already have the bird. If you try to catch another, however, you risk losing the bird in your hand and also whatever it was you were trying to catch. Now you have no bird in hand, and there is no guarantee that you will get the two in the bush. In other words, it’s better to be sure about something smaller than to be unsure about something bigger.
That was the online explanation - GOT IT ! I think I have now .
