Those Deceptive Blue Jay Feathers!

From USFWS Northeast Region:




Did you know that blue jay’s feathers are not actually blue? The feathers are constructed in such a way that they distort the reflection of light, and as a result, the feathers appear blue. If you hold a blue jay feather just the right way, it will appear gray. (Randy Loftus/USFWS)
