Pellets are found in different locations, depending on the species. In general, these are roosting and nesting sites: for most hawks and owls, under coniferous trees; for barn owls, at the bases of cliffs or in barns and silos; for yet other species of owls, at their burrows or in marsh and field grasses.

They make several different calls, which include a hissing call of short duration. The song calls are short and mellow unlike those of most owls. They are usually disyllabic, "oh-owow" but sound monosyllabic and each note ascends and descends rapidly. The territorial calls have been transcribed as "kwaak … kk, kwaa..kk".
The pellets are typically grey coloured and are found in groups under trees used for roosting or nesting. At least some tawny owl pellets can measure up to 84 mm (3.3 in) long and can include large objects such as an intact 10 cm (3.9 in) bill of a snipe.

The Andaman masked owl (Tyto deroepstorffi) is a barn owl endemic to the southern Andaman Islands archipelago of India, in the Bay of Bengal, Indian Ocean. [2] Regarded by some authors as a subspecies of the common barn owl ( Tyto alba ), it is recognized by others as a species in its own right.
Scientists study the owl pellets to keep track of vulnerable or endangered species in the area since sooty owls are known to prey on these species. Owl pellets are compact clusters of partially digested food pieces like fur, bone and feathers that the owl regurgitates from its gizzard.

The Australian boobook (Ninox boobook), is a species of owl native to mainland Australia, southern New Guinea, the island of Timor, and the Sunda Islands.Described by John Latham in 1801, it was generally considered to be the same species as the morepork of New Zealand until 1999.
To better triangulate sounds and make hunting easier, the pygmy owl's ears may be asymmetrically placed. [12] Female owls tend to be bigger than males. [13] Some species of pygmy owl, including the northern pygmy owl, have ocelli on the back of their heads. [14] These eyespots may contribute to the owls' self-defense against mobbing. [15]
