I find it fascinating how scientists still haven't definitively figured out how magnetoreception in birds works. Humans have utilized homing pigeons for thousands of years [1], but it is still a mystery as to how it works. To quote a paper from 2019 [2]:

> Yet in spite of considerable progress in recent years, many details are still unclear, among them details of the radical pair processes and their transformation into a nervous signal, the precise location of the magnetite-based receptors and the centres in the brain where magnetic information is combined with other navigational information for the navigational processes.

I thought I read that they had detected something in the birds' eyes.
