A pellet, in ornithology, is the mass of undigested parts of a bird's food that some bird species occasionally regurgitate. The contents of a bird's pellet depend on its diet, but can include the exoskeletons of insects, indigestible plant matter, bones, fur, feathers, bills, claws, and teeth. In falconry, the pellet is called a casting.
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. [7] [1] [29] [32] Undigested material coughed up often reveals different prey than pellets ...
The supposed "giant barn owl" Basityto from the Early Eocene of Grafenmühle (Germany) was actually a crowned crane (Balearica); [16] the presumed "Easter Island barn owl", based on subfossil bones found on Rapa Nui, has turned out to be a procellarid; [17] and the specimen originally described as the fossilized Pliocene Lechusa stirtoni was ...
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. [15] Owls from the family Tytonidae are known to eat their ...
The tawny owl holds a place in human folklore: because it is active at night and has what many humans experience as a haunting call, people have traditionally associated it with bad omens and death. Many people think that all owl species make a hooting sound, but that is an overgeneralization based on the call of this particular species.
The longest great gray owl was 120 mm (4.7 in) longer than the biggest Blakiston's fish owl but would be about 2.5 times lighter than the weight of the largest female Blakiston's. [8] However, the average measurements of Blakiston's fish owl surpass the average measurements of the Eurasian eagle-owl in at least two of the major categories ...
The barred owl (Strix varia), also known as the northern barred owl, striped owl or, more informally, hoot owl or eight-hooter owl, is a North American large species of owl. A member of the true owl family, Strigidae, they belong to the genus Strix , which is also the origin of the family's name under Linnaean taxonomy .
The northern saw-whet owl (Aegolius acadicus) is a species of small owl in the family Strigidae. The species is native to North America. Saw-whet owls of the genus Aegolius are some of the smallest owl species in North America. They can be found in dense thickets, often at eye level, although they can also be found some 20 ft (6.1 m) up.
