What a weird expression. And what the heck does it mean? I googled it.
"a bird in the hand. Something of some value that is already acquired. Taken from the proverb "a bird in the hand is worth two in the bush," which means that having something, even if it is a lesser quantity, is better than taking the chance of losing it in order to attain something else that seems more desirable."
So...playing it safe? Basically.
