A plumicorn is one of the tufts of lengthened feathers found on the head of various owls. These distinct feather extensions are a notable characteristic of many owl species, contributing to their unique appearance and natural behaviors.
Understanding Plumicorns
Often mistaken for ears or horns, plumicorns are purely ornamental feather structures. They are not involved in hearing and are not bony outgrowths like antlers or horns. Instead, they are highly mobile feather tufts that an owl can raise or lower, giving the bird a changeable silhouette.
Functions of Plumicorns
While not directly functional for hearing or defense in the way a horn might be, plumicorns serve several important purposes for owls:
- Camouflage: By breaking up the owl's head shape and helping it blend into its surroundings, plumicorns provide excellent camouflage. When an owl is resting or trying to avoid detection, these tufts can resemble branches or broken bark, making the owl almost invisible against tree trunks.
- Visual Display: Plumicorns can be used in various social contexts. Owls may raise or lower their plumicorns to communicate with other owls, whether for courtship displays, territorial warnings, or to express their mood or alarm.
- Species Recognition: In some cases, the specific shape and size of plumicorns can help in distinguishing between different owl species, particularly those that are similar in appearance.
Owls Featuring Plumicorns
Many well-known owl species are recognized by their prominent plumicorns. Examples include:
- Great Horned Owl: Known for its large and prominent ear tufts, which are classic examples of plumicorns.
- Eurasian Eagle-Owl: One of the largest owls in the world, also sporting distinct feather tufts.
- Long-eared Owl: As its name suggests, this owl has very long and slender plumicorns, which give it an elongated head profile.
- Screech Owls (Eastern and Western): Smaller owls that also possess noticeable feather tufts.
