Blue-and-yellow budgie with orange beak, leg band

I lost my blue-and-yellow budgie yesterday around 6pm. He's palm-sized, with bright plumage and a tiny white dot on his left wing. I last saw him perched on the kitchen window ledge near the New River Valley Mall area, around Prices Fork Road, and he bolted when the back door opened. He wears a red plastic leg band with the initials 'RV' and he answers to 'Sunny'. He's really anxious but friendly, and this little guy means a lot to me—please help me get him back.
