Where do birds and insects go when it rains heavily?

Just watching this downpour over here and it got me thinking. Insects can probably go underground, but what if they need to eat? And birds can probably fly above the rain but not for that long.

Back to their nests. Usually within tight foliage which provides protection from the wind and rain.

On top of that, within a nest you only have one point of entry or only open from the top. The structure of birds wings creates, what's is effectively a tent shelter.

Ever seen a 'survival' type show... where they cut lengths of tree branch etc create an A-Frame and layer foliage across the top. In the same way roof tiles are laid.

The birds will generally have a raised platform and from their own limbs a tiered 'roof' of the feathers on their body. Put together they have a pretty tight rain hut.

Some birds will also huddle or seek refuge in out of the wind places.
