Barn Owls Let You Know
© Bob Moul
The structure and delicate softness of its feathers allow a Barn Owl to approach its prey almost without sound. The Barn Owl's ability to locate prey by sound, even when concealed by snow or leaves, is the most precise of any animal yet tested. This young Barn Owlet is about five weeks old and actually weighs more than its parents. During and after the fledging period, it will gradually lose weight, as it learns to hunt for itself. Be sure to watch the video of an owl hunting.

Barn Owls Let You Know
Written by Chris Peterson
This is BirdNote!
[Distant sound of Barn Owl owlets begging]
It’s 11PM, and we’re camped in a field ringed by tall evergreens, backlit by a full moon. If we’re quiet, we’ll hear two full-sized juvenile Barn Owls begging for food. [Barn Owl owlets begging]
If we could see these owlets, we’d see large eyes set in heart-shaped faces atop big fluffy bodies of cream-colored down. At five weeks old, these young actually weigh more than their parents. During and after the fledging period, they gradually lose weight, as they learn to hunt for themselves.
This is a rare treat! Let’s get a little closer.
[Keeeeeerrrrrrr!] At 40 yards, we’ve crossed the line. That’s a parent, most likely the mother, saying, “Stay away! You’re getting too close to my children!” [Keeeeeerrrrrrr!]
A Barn Owl has the best hearing of any animal yet tested, so she’s been aware of our presence for a long time. [Keeeeeerrrrrrr!]
OK, that’s close enough. She has a busy night ahead. [Keeeeeerrrrrrr!]
Let’s retreat into our tent [ziiiippppppp], admiring her fortitude and determination to keep us away. While we sleep, she will hunt for voles, flying like a giant, quiet moth over moonlit fields. [Keeeeeerrrrrrr!]
