are birds copycats in their songs, some certainly are but are all?

Was listening to longer versions of:

and several other recordings of warblers and seemed to hear little chunks of other species calls incorporated into their song.
If they are copying little bits of other birds calls then I suppose its a way of making their call distinct and local to that area with its particular mix of other species.
