ELI5: how do birds stay in the trees on really windy days?

I watch my heavy garbage cans blow over from the strong wind but I have never seen a bird blow away! How do they stay in the trees during storms and strong winds?

They have perching feet that are designed to clamp down harder if something tries to pull them off a branch so they won’t get blown out of a tree, but they’re also not that interested in going for a roller coaster ride as the treetops get lashed by wind gusts.

During extreme weather, birds will shelter near the center of trees with good leaf cover or in lower shrubs.

They usually don’t try to fly unless necessary, it’s difficult and tiring to navigate in strong winds.
