I'm reading "bachteria to Bach" by Dennett and he talks about this I believe. Birds that are born/raised without their mother can build a species-like nest their first year, and will build a better nest the following year, but will build a better nest the first year if they aren't taken from their mother. So the book talks about learning vs hard wired. The idea in the book is that nest building is both, but seemed quite a bit hard wired
