Peregrine chicks at this age have two speeds: naptime and "want food".
A little later it becomes: naptime, "want food" and "move over".
At fledging its: naptime, "want food", "move over" and "where'd you go?!".
Post-fledging its: "want food" and "wait for me"
At migration: "hasta la vista baby" and "I'll take that to go"
