I like birds, & am fascinated by their feathers' colours. This rainbow lorikeet feather has four distinct colours - more if you count the shades of grey - reminding me that I've often wondered. How does that work? Why is a single feather so variable? How do they grow? If only I could access some world wide resource and find out.💡🔔
I found some AI crap, but also this from the Cornell Lab. I thought it was interesting. 🤷♂️
