No. Humans have nothing to do with it. My many parakeets, greet me when I come home from work with "Chirp!" which means "Hi" I say to them "How are my babies doing?!" they sing into response of my question. They know who you are and they are aware! Parakeet lover from day one!

Passerine birds are generally your smaller birds that perch on branches and sing songs by tweeting etc. Non-passerines are birds that do not perch and sing and tweet. For example, an eagle or an ostrich are both non-passerines as they do not chirp or tweet songs, where as things like sparrows and most birds you find in your backyard do tweet all day and perch. These are your passerines.
