Bright yellow budgie with blue leg band

I lost my bright yellow budgie yesterday afternoon around 3pm near Afflecks Palace on Oldham Street in Manchester. He's palm-sized, mostly yellow with green-tipped wings, and he wears a blue leg band on his right leg with the code MQ-72. He's incredibly curious and chatty, and he answers to the name Loki when I rattle his seed jar. One distinguishing feature is a tiny white patch on his throat and a slightly frayed tip on his tail feather. This little guy is all I have left of my grandma's rescue birds, and I really need him back.
