Nature, 2000
The elongated dorsal appendages of the reptile Longisquama insignis , from the Triassic of Kyrgyzstan1, have recently been reinterpreted as the first record of feathers in a non-avian tetrapod2 — long predating the feathers of the oldest known bird, Archaeopteryx. Here we present evidence that the dorsal scales of Longisquama are not feathers, and that

Feathers are the most complex integumentary structures in the animal world. They come in a variety of forms, the most familiar of which are remiges (flight feathers). Flight feathers are composed of a central shaft made up of a hollow calamus (quill), which is inserted into the skin, and a more distal rachis.

Feather pecking and feather loss.
2004Characterizing feather peckers seems a viable approach towards a better understanding of the problem of feather pecking. With our current state of knowledge on the causation of feather peckinq, the environmental factors that influence the development of feather pecking and the characteristics of feather peckers and non-feather peckers, it should be ...

Journal of Cardiovascular Computed Tomography, 2009
A 57-year-old man presented to an outside hospital with episodes of persistent fever. On further history, the patient stated that his current condition started when he "stuck" himself in the back with a "sharp feather" protruding from his sofa 2 weeks before. He underwent transesopheageal echocardiography (TEE) to assess for endocarditis. TEE showed no

Allergy, 1998
Skin prick test reactivity to commercial and self‐made feather‐allergen extracts was examined in 269 consecutive adult patients with suspected allergic cutaneous or respiratory symptoms who had been referred to a university clinic. Some 177 subjects reacted to any inhalant allergen.

Feather Mites, Feather Lice, and Thanatochresis
The Journal of Parasitology, 1984Unrelated taxa of feather mites use exuviae of their own, or closely related, species for molting within quills or on feather surfaces of diverse groups of birds. On the Orange-fronted Conure (Aratinga canicularis (L.)) and other parrot species, feather mites and mallophagan eggs coinhabit the same feather area, mites molt within the exuviae of other ...
