Owl emoji is the picture of a huge predatory 🐦 Bird — in this sense, it may be compared with 🦅 Eagle emoji. However, the Owl lives the 🌃 Night lifestyle, keeping asleep at the daytime — so it is used in relation to people who keep the similar schedule. This 🐦 Bird is a symbol of wisdom and also it has become something like a pop culture phenomenon because of its crazy 👀 Eyes. So it may be used in the meaning of madness, being very scared or surprised.
Examples of using
“The owls’ eyes are so crazy 🦉”
“I want to have an owl as a pet 🦉”
