eli5 How do small birds not blow away when it’s windy?

It’s really windy here today and I’m watching this bird feeder swing back and forth.  How do the really tiny birds not blow away in the wind?  Do they hide in a nest and grip onto it to stay still?

Birds are blown around when the wind blows.  Watch one when it flies past the edge of a building, and you'll see the wind blow it.  

Birds can fly, and wind is always a potential thing, so they just learned to deal with it.  If the wind blows one left, they just steer back to the right to compensate.

To remain still, birds need protection from their nest, or the tree the nest is in, or the building next to the tree where the nest is located.  Birds pick places to hang out during windy periods with these features in mind.
