Anytime the birds are in a program or traveling, they rest inside a crate. These custom-made boxes have solid walls with small holes for ventilation. It might not seem like a pleasant place to us, but the dark environment helps the bird feel calm when outside the mew. Raptors are easily agitated by visual stimuli. Whether there is just one person or one hundred, watching unpredictable strangers in an unfamiliar place can be scary for the birds. Their sharp eyesight might help them spot a quick-footed mouse in the wild, but also makes for some stressful situations for an education bird. Their dark, secure crates help them stay calm by blocking their view of the activity around them.
