Question

why were the birds worried​

Answer 1

Answer:

There is a Chinese expression, "That the birds of worry and care fly above your head, this you cannot change. But that they build their nests in your hair, this you can prevent."

Worry can fly over you; or you can let worry build a nest in your mind. You can choose whether you allow worry to be a momentary emotion; or, whether you decide to let worry become your lifestyle. We cannot control circumstances; but we can control our reactions to them. Worrying is something you can decide not to have "nest" in your psychology.Generally, worrying is a natural emotional reaction that people experience. To experience worry is not necessarily negative. The critical issue is whether you let worrying take control of you, or whether you take control of worrying.

Answer 2

Explanation:

Researchers from the Cornell Lab of Ornithology conducted research from 2009 to 2011. The purpose of their study was to see whether chickadees spend more time worrying about lack of food or whether they might be eaten by a predator.

The researchers were able to tally the visits of individual birds to feeders over two winters. They recorded 472,368 visits by 94 birds.
