On 1st glance I thought this wee one was collecting nesting material until I got the camera for a closer look.
Poor wee BT
He looked in good health otherwise ......

Beauty is in the eye of the beholder.
I was just doing a quick search there CL and founds Hazel's from 5yrs ago..as you say no where near the length of mine. I will need to keep the swing feeder topped up for the wee one.

Lot to learn
Poor wee thing. Its done well to get this far, and it is amazing how nature manages to move on with such abnormalities!
I fear nature will take charge unless someone can catch the blue tit and trim the mandible.
I raised a similar post a couple of years back about a coal tit, but nowhere near as bad as that; "Coal Tit with crossed over beak!"

Also mentioned in there is a link from Hazel to report sightings like that. The link is :https://www.bto.org/our-science/projects/gbw/about/background/projects/bgbw
Incidentally, we still see coal tits with crossed mandibles, and often two or three at a time, so it could be a genetic mutation here. But they seem healthy enough, and get on with the daily business of feeding and surviving.
