Humans are exposed to so many opportunities, so many rules and systems... we have many conveniences but this also creates more opportunities for abuse and neglect of ourselves and others. Life is a lot harder for these birds, and many won't survive their youth, but the path for the parents has few distractions and as such, they never question their desire to be parents.
These birds are wild, but me and my little dog have good calm energy. They didn't appear to be concerned with our presence.
