In falconry, the pellet is called a casting. The passing of pellets allows a bird to remove indigestible material from its proventriculus, or glandular stomach. In birds of prey, the regurgitation of pellets serves the bird’s health in another way, by “scouring” parts of the digestive tract, including the gullet.

I also explained that the yellow color in bird beaks, ceres (the fleshy portion at the base of a raptor’s beak), and feet are caused by pigments called carotenoids.
Why do chickens move so jerky?
Birds’ movements are so jerky because they use mostly head movement, but minimal eye movement to switch their gazes between objects rapidly and achieve depth perception. Birds’ rapid head movements are possible due to traits such as light heads, very flexible necks, and a very high metabolic rate.
Why do hawks mantle?
In the nest, young hawks may mantle over prey their parents provide. Even if the prey is already dead, this action guards the food from hungry siblings as these young birds become more independent and rely more on their own hunting instincts. In some cases, scavenging raptors will mantle over carrion.
Why do owls spit up pellets?
Indigestible material left in the gizzard such as teeth, skulls, claws, and feathers are too dangerous to pass through the rest of the owl’s digestive tract.

What kind of feathers did the Velociraptor have?
While the Velociraptor was featherless in the movies, paleontologists discovered quill knobs (places where the flight-related feathers of birds are anchored to the bone) on a well-preserved Velociraptor forearm from Mongolia in 2007, indicating the dinosaur had feathers.
Why does a diurnal raptor lose its vision?
As a result of the low density of rods, and the narrow and densely packed single cones in the central fovea, the visual performance of diurnal raptors drops dramatically as light levels decrease.
