Ear tufts are a collection of fur or feathers found on animals which can resemble an animal's ear or is near the animal's ear.
CatsEdit
Ear tufts are not found on all cat breeds.<ref name="Catster">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> The ear tufts are located on the tips of cat ears and are also known as lynx tipping.<ref name=Catster></ref> Cat ear tufts are often confused with cat ear furnishings which is the fur that comes out of the opening of the ear.<ref name=Catster></ref> Cat ear tufts assist with keeping debris out of the ear and guides sound into the ear canal. <ref name=Catster></ref>
BirdsEdit
Bird ear tufts are skin projections covered in feathers found in some bird species, most notably various species of owl, vaguely resembling mammalian ears, but unrelated to the animal's hearing. Theories about their function range from improved ability to camouflage,<ref name="Perrone">Template:Cite journal</ref> aiding in finding a suitable mate,<ref>Template:Cite book</ref><ref>Template:Cite book</ref> to giving a more threatening appearance to discourage predators.<ref name=Mysterud>Template:Cite journal</ref>
In Araucana chickenEdit
In the Araucana breed of chickens, ear tufts are a mutation. It causes a skin projection covered in feathers to appear on the sides of the head near the ears. This mutation is dominant semi-lethal. Consequently, ear tufts are very unusual and difficult to breed, as most Araucanas are hatched without tufts.<ref name="Ear tuft">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
Lethal geneEdit
Ear tufts in the Araucana breed of chicken are associated with a lethal gene: An ear tufted hen mated with an ear tufted cock produce chicks with deformed ears and mouth that die before hatching. Also, the rumplessness of the breed makes breeding Araucanas together have very short backs. In any other chicken breed, ear tufts are undesirable. <ref>The Chicken Encyclopedia by Gail Damerow, pg. 59</ref>
