The bird man has java sparrows for sale. I recall that they were my aunt's favorite birds, and were my first exposure to pet birds. She kept them in a cage hanging below the intricately-carved archway between the living room and the dining room in our ancestral, Fil-Hispanic house in San Fernando, Pampanga. Whenever the cage door was left open, the sparrows would fly out and, at the end of the day, return inside.
