In the Guardians of Ga'Hoole series, the owls use some unique vocabulary, which will be described here.
Yarp: To cough up a pellet.
Wet poopers: A derogatory term for birds other than owls, who do not process waste in pellets, but in a less cleanly manner.
To go yeep: For an owl to be extremely shocked or frightened while flying, causing their wings to lock in place and make them plummet to the ground.

Gleeking about: Fooling around; not being serious.
Glaumora: A special heaven for owls.
Hagsmire: The owl term for hell.
"The Yonder:" The term used by nest-maid snakes to refer to the sky, as it is the farthest thing from the ground that they can imagine.
Scroom: The spirit of a dead owl, similar to a ghost.
Slipgizzle: A spy, or someone who gathers information and reports it to another group.

Tapping: The process of owls new to the Tree being selected for certain chaws.
