Question

How do birds use wings to find food ?

Answer 1

It is the feathers that make the birds unique.

Feathers are mainly used for the purpose of foraging. In other words, these are used by them to look at the food.

Certain birds form umbrella like structure with the wings that help them to get into the water easily in order to get the fishes.

Answer 2

Foraging (Looking for Food) Somebirds, like herons that hunt for fish in the water of lakes and streams, will sometimes use their feathers to form an umbrella over their heads. This might make it easier for them to see fish in the water.
