Porphyrin pigments in feathers fluoresce under UV light, allowing biologists to more accurately classify the age of owls. The true owls or typical owls (family Strigidae) are one of the two generally accepted families of owls, the other being the barn owls (Tytonidae). [2] They tend to have large heads, short tails, cryptic plumage, and round facial discs around the eyes.

They are often perceived as tame since they allow people to approach quite closely before taking flight, but they are instead attempting to avoid detection. The feathers of the facial disc are arranged in order to increase sound delivered to the ears. There are three accepted subfamilies of Strigidae including Striginae, Asioninae, and Surniinae. This creates cushiony air pockets that allow for more movement of the artery when twisted. [7] Numerous species of owls in the genus Glaucidium and the northern hawk-owl have eye patches on the backs of their heads, apparently to convince other birds they are being watched at all times.
