What would be in the pellet of a seagull?
Expect to find in the pellet of a seagull bones and fur and feathers the seagull has eaten. The relatively small amount of indigestible bone and fur that remain will be compacted by their stomach muscles into a pellet similar to the owl’s.
What birds form pellets?

Do seagulls cough up pellets?
The gulls common to the area are Herring and Ring-billed. I assume one of them coughed this up. Birds expel pellets in a manner similar to a retch. A study done on a wildlife refuge in Montana during the 1990s found that small mammals were the most numerous prey items found in Ring-billed Gull pellets.
Do all owls cough up pellets?
Young owls do not produce pellets until they have begun to eat their prey whole. These spasms make the owl look like it is coughing painfully. However, it is not hurt by the process because the pellet remains soft and moist until it leaves the owl’s body.
Do seagulls cough up bones?
The stomach — and it appears that birds have stomachs much superior to ours — takes bones and fur or fish scales, and forms a mass that the bird then hacks up. Fur forms the casing of the pellet. It covers sharp bone ends, easing passage of the pellet as it’s coughed up and out the throat.
Do owls cough up bones?
Owls swallow their prey whole or in large pieces but do not produce enough stomach acid to digest bones, fur, feathers and scales. After several hours, a gizzard-shaped owl pellet is produced. Once formed, the pellet moves back into the owl’s glandular stomach.
Do Owls poop out bones?
The owl pellet of a Northern Pygmy-Owl. Photo by Anne Elliott via Birdshare. Owls swallow their prey whole or in large pieces, but they cannot digest fur, teeth, bones, or feathers. The remaining, indigestible fur, bones, and teeth are compacted into a pellet which the owl spits out.
