Proverbs (traditional sayings) can tell you a lot about the culture and ideas of those who speak a certain language. I’d thought it would be fun to take a look every now and then (occasionally) at some popular proverbs. Today’s is “A bird in the hand is worth two in the bush.”
This expression means that it is better to keep what you have than to risk (take a chance) it for something greater. Having one bird in your hand is worth more than trying to catch two birds that are in the bush (a large plant). You have to let go of (release) the bird that is already in your hand in order to catch the other two birds, but of course you may fail and end up with (have at the end) no birds at all. Because of the risk of loosing the little you have, it is sometimes better not to try to get something more and end up with nothing.
