A few years ago, I caught a mountain Chickadee as part of a banding operation with a similar bill configuration. upon close er examination, it have a jaw injury that made his lower mandible off line with his upper. I took a finger nail clippers and reformed it's bill. Its a common practice with falconers.

According to some research, such birds carries a new form of virus but scientists haven't established the causal relationship between the virus and the deformed beak yet (https://news.
