From Doc’s Veterinary Wildlife
Owls come in all sizes! We could not resist the opportunity to compare the size of the northern saw- whet owl, weighing 104 grams, to the Eurasian eagle- owl, weighing 2900 grams. And yes- both birds are fully grown!
These are not even the largest and smallest, though they are close to both extremes. The Elf Owl is smallest, followed by some types of Pygmy Owls, and the Blakistons Fish Owl is usually a smidge larger than the typical Eagle Owl.
Owls are so deceptive with their weight!
You absolutely can boop it, but the question is should you boop it. Owl beaks are nowhere near as strong as the feet, but it could still give you a permanent reminder of the time you booped an owl! 😅
