Did I show you guys the feather I found in my back yard? It's from a blue jay, I just thought that it was pretty.

@nonayadambidnes Very cool and even cooler because that blue is prismatic; not from pigment.
Proof, take a Blue Jay, get it wet. Not blue anymore.
@nonayadambidnes yep, the feather structure scatters light such that blue is reflected. The pigment in there is brown.
@b4cks4w That is very cool. I'll have to check these guys when they're in the birdbath next summer and see if I notice the color change!
@b4cks4w Oh that's interesting. I noticed that the other side of the feather is just grey with the white tip, so the blue is only on one half of one side. I wondered how they managed to do that - would the fact that it's prismatic explain it?
