#bluejay ( #Cyanocittacristata )
“As with most other blue-hued birds, the blue jay's coloration is not derived from pigments but is the result of light interference due to the internal structure of the feathers; if a blue feather is crushed, the blue disappears because the structure is destroyed. This is referred to as structural coloration.”
