Once in awhile when I glance out my apartment front window, I see a 'hybrid' bird. A few weeks ago, a real strange but kind of cute in a 'odd' way. A bird that look like 'budgie parakeet', but also look like a sparrow, had combination of soft pastel green on its belly, a parakeet head, and grey wings of a sparrow. Its size was small, like a sparrow, and its voice was kind of mutated. It was flying with sparrows. They had accepted it, like it was a member of the family flock.
