“Some things you miss because they’re so tiny you overlook them. But some things you don’t see because they’re so huge.”

The four Great Horned owlets near the Refuge headquarters have fledged from their nest. I visited with the entire family for a few hours the other day as they roosted in two large cottonwood trees. I was privy to some interesting behavior and interactions.
At six to eight weeks old, Great horned owl nestlings will begin to venture from their nest. By climbing branches or other structures next to the nest, the young begin to exercise and strengthen their leg muscles. They will also flap their wings for the same purpose, often jumping around in the nest while flapping. At this stage, these nestlings, and other large birds of prey, are referred to as ‘flappers’. They will then progress to taking flight for short distances.
The four owl siblings were often spotted flying around inside the fire tower structure, where they could safely exercise without falling to the ground. It was like a large playpen for these owl youngsters. We knew then that they would be fledging soon outside of the fire tower box and take wing.
Owl fledglings remain in close proximity for several weeks. They will often roost together in the same tree or in neighboring trees. Adults generally roost away from the young, albeit nearby, and they will continue to feed their young with decreasing frequency throughout the summer.
I spotted three of the youngsters with the dad in one tree. The lone sibling was in a tree across the way with mom. I heard the adults communicating with each other shortly before I spotted them, which is how I identified the gender of the adults. A pair of nesting ravens (in a spruce tree ~400 yards from the cottonwoods) tried harassing the lone owlet. Mom had enough and chased them off.
I quietly chuckled while watching the group of three youngsters preen each other while perched on a large tree branch. When one tried preening the feathers on its sibling’s leg, it got a foot of talons in its face. So it stepped on its siblings foot and proceeded to continue preening its leg feathers, while the other tried in vain to pull its leg away. All the while, third sibling did it’s rolling and bobbing the head-thing while watching its two siblings argue about pedicures.
I returned later with the camera and found that the siblings had separated. Two were deep in the shade of the tree canopy, their heads pulled down into their shoulders and wings. They blended in quite well with the rough bark of the tree. One lone sibling was still awake, watching below and in plain view. I set up the tripod and zoomed in for a few portraits. These youngsters still have some downy feathers on their heads, which makes them look lighter than the adults.
As the day was getting warmer and brighter, this one eventually succumbed to nap time. It very slowly tilted to the side and laid prone on a branch next to it.
Unfortunately, a visitor appeared, yelling out, “Whatcha watching there?! Anything good?!” Because it was my day off, and I was not in anything associating me with refuge staff, I told him to be quiet!
