When bird find mate they will build a nest
The doctor bird uses silk from the spider web to build their nest.
There is no such bee species.
A baby learns it from its mother while it is young as it learns everything else. A bird building a nest is an instinctive behavior they are not taught how to do it they just know how to do it. The nest for chicks is prepared before they are born and the chicks leave before more chicks are born so they don't have the opportunity to learn in the sense humans learn at school, how to build a nest.
