Green-yellow cockatiel with orange cheeks, lost near Arcata

I’m hoping someone spotted Mango, my 2-year-old cockatiel. I last had him on my shoulder yesterday around 3pm near Arcata Plaza by the farmers market, and he darted into the trees behind the plaza. He’s a gray cockatiel with a bright yellow head and orange cheeks, about the size of a canary, and he wears a red plastic leg band with the letters 'MNG' plus a small white splotch on his left wing. If you see him, I’d love to get him back—he’s a gift from my grandmother and I’m really worried. You can email me at [email protected] if you’ve got any tips.
