Oscar's first day in my apartment

Oscar the fledgling had a fun-filled day. He jumped out of his box 3 times. Luckily Manolo the cat didn't notice. He chirped a few times. He seems to like it when I sing. He likes recorded music also, especially my musical theater mix. I gave him some birdseed. I think he might be ready to fly soon. I wonder how I will know when he's ready to face the world?
