Male bowerbirds construct elaborately decorated nests

Here is a paragraph:

Male bowerbirds construct elaborately decorated nests, or bowers. Basing their judgment on the fact that different local populations of bowerbirds of the same species build bowers that exhibit different building and decorative styles, researchers have concluded that the bowerbirds' building styles are a culturally acquired, rather than a genetically transmitted, trait.


can you please tell what does it mean by culturally acquired ?
can you give some real example ? i am getting difficulty to understand this thing
