Pellets are found in different locations, depending on the species.

In some cases, pellets of Bubo owls can range up to 150 mm (5.9 in) in length. [3] [9] Eagle-owl pellets average slightly larger (about 10%) than those of great grey owls (Strix nebulosa).

These "owl pellets" are plentiful and easy to interpret, and are often sold by companies to schools for dissection by students as a lesson in biology and ecology. [37]

The New Providence site contained only two partial skeletons, but also copious amounts of owl pellets. These show that T. pollens had a diet which was largely based on the large rodent Geocapromys ingrahami , which at present only survives on a single small arid island, but which appears to have once been the only land mammal of the Bahamas and ...
