That's v interesting. My last bird ring was last month detecting aluminium and had 1935 written on it and a number 25. I have kept them lately, but thanks I hadn't realized their relative value. I just read an article that says possibly proteins in certain animal's eyes called cryptochromes orient their field of view in accordance with the Earth's magnetic field so they use visual cues and this compass view together to navigate. I think I also read they got disorientated during mass coronal ejections from the sun which interferes with the polarisation of Earth's field.
We’ve found a couple now and it’s always a joy when they come up! Their navigation skills are unmatched! Looking into the history behind them definitely gave us a greater appreciation. A medieval bird ring would be a bucket lister!
Wow I love this story!
There’s so many underrated artefacts to delve into! We’re glad you enjoyed this one ☺️
