Blue budgie with yellow head, lost near Woodstock

I’m really worried—yesterday around 3pm I realized my budgie had slipped out during a quick break from cleaning the aviary. He’s a small parakeet, sky-blue body with a bright yellow head, white cheeks, and a lilac tail, about the size of a sparrow. He wears a tiny pink leg band with 'AK-42' engraved and there’s a small white patch on his left wing that looks a bit like a heart. I last saw him around the Woodstock Village Green on Tinker Street, near the Woodstock Farmers Market, but he’s likely flown toward the hills around the Catskill forests. This bird is a gift from my grandmother and really means a lot to me—please help me get him back.
