Great Horned Owl FAQs

Will Great Horned Owls nest in my owl box?

Alas, no. Great Horned Owls prefer open platforms for nesting. However barn owls love owl boxes as long as you live in or near an open meadow or vineyard.

Do I need to maintain my Great Horned Owl platform?

Typically not. Great Horned Owls are pretty messy and move from abandoned nest to nest (or platform). As they are about 25 ft or higher, it can be difficult to clean them.

Owl boxes for barn owls, on the other hand, should be cleaned annually in the fall once all the fledglings have left.

Can I put an owl cam in my platform?

If it's a solar powered bird cam with Wifi and your home's Wifi can reach your owl platform, yes! Obviously you'll just need to install it on the tree trunk slightly above your owl platform.

Do Great Horned Owls build their own nest?

No, great horned owls do not build their own nests. They use existing structures like abandoned nests from other birds (hawks, crows, herons) or use tree cavities, rocky ledges, and artificial platforms.

How high should owl platforms be?

A height between 20 and 30 feet is a good range, though higher is better if possible, according to Birding Wire.

Should my owl platform have moss and small twigs?

It's not necessary. While it may be very inviting for a nesting Great Horned Owl pair, they will add nesting material if needed. Typically, many nests are quite messy and dirty.
