Owl-o-ween!

Seen as a creature of the night, with its silent hunting, spook-tacular stare and eerie screech, the owl has long been a symbol associated with Halloween.

But did you know not all owls are nocturnal? And it’s their eye colour which gives away their preferred time to hunt!

Owls who hunt during the night and sleep during the day have dark brown / black eyes. Here at DZC the likes of our Asian brown wood and the barn owl are nocturnal – although some barn owls will hunt before dusk and dawn, especially when they’re feeding young.

If they have striking yellow eyes, such as our Snowy, Great grey, Northern Hawk and Burrowing owls, they’re active during the day and sleep at night, which is known as a diurnal active species.

And if they sport orange eyes, this indicates the species prefer hunting in the low light of dawn and dusk. They’re known as a crepuscular species, which include our Eurasian eagle owl and Coast Horned owl.

Like humans, owls have binocular vision, so they can see something with both of their large eyes at the same time.

But unlike humans, their eye balls are not actually spherical, instead they’re long tubes which helps with their long-distance vision when hunting.

And they can’t move their forward-facing eyes in the sockets, so have to rotate their head to look around – but it’s a myth that they can rotate fully around, as they can only twist to a maximum of 270 degrees!
