The <a href="http://www.themodernapprentice.com/glossary.htm">Modern Apprentice</a> defines a warble as \'The action of stretching both wings up over the back simultaneously\'. So why is this a milestone? As the \'wing part\' of D32\'s brain lights up, it is learning how and why to move its wings. While D32 won\'t make its first flight for another 60 days or so, it is already beginning to explore and strengthen its wings and wing muscles in preparation for flight. Pre-flight, D32 will use its wings to help it balance as it learns to shuffle around the nest and stand and walk on its feet.
