While the study is about magnetoreception in migratory birds, there are possible implications for human heath, see my notes and references for further reading:

Amazing! Thank you for sharing.

I would love to hear CPT_Helen (uniquely qualified) give the "for dummies" version of how "magnetoreception" is relevant or "on topic" for PD.

As I noted there are implications for human health since geomagnetic field fluctuations (mainly caused by solar flare activity) have been found to be associated with heart attack & pwPD suffer higher rates of CVD. There's also the effect on heart rate variability, a measure of autonomic function & dysautonomia is a problem in PD. It would be interesting to know whether SUDPAR incidence is correlated with solar flare activity.

There's also a really weird rat study that found higher levels of neuromelanin accumulation in the brains of rats that were exposed to artificial light. Cryptochrome activation is light dependent. However, the rats had had their optic nerves severed - but it is not known how the signal from cryptochrome activation is relayed and it may not be via the optic nerve. I had previously suggested that the neuromelanin accumulation was the result of the rats' skin being exposed & producing circulating factors that affected the brain - but cryptochrome activation could be a another possibility.

I wrote about the study in this post (which is a bit long and covers a lot of other topics - can use CTRL-F 'optic nerves' to find the relevant bit):

It's possible the signal transduction could be via the ophthalmic tract of the trigeminal nerve.

There's a free app that measures local magnetic fields called CrowdMag from NOAA (National Oceanographic and Atmospheric Admin.) - listed for helping to improve navigation, but data could be used in epidemiological studies in future. It did not work on my phone, but it worked on my husband's.
