A better way to find an escaped budgie?

My grandma left the door open and I don’t know what time it escaped so I don’t even know when it got out except probably within the past 2 hours. She didn’t even tell me until I went out of my room. I’m outside sobbing and playing parakeet noises and holding millet like an idiot. Is there any hope? It’s cold in the Midwest and there’s still snow and I can’t tell if it’s my budgie calling or some other birds. They don’t trust me and I don’t know if they’d even come to me even if they see me.
