Q: Are feathers caused by various carotenoids? ¶
Q: Was feather te has been used in a number of industrial applications as a medium for culturing microbes? ¶
A: Yes, and biodegradeable polymers, and production of enzymes.
Q: Are feathers crushed and the feather remains or imprints are preserved? ¶
Q: Are feathers among the most complex integumentary appendages found in vertebrates and are formed in tiny follicles in the epidermis? ¶
A: Yes, or outer skin layer, that produce keratin proteins.
Q: Were feathers used in the past to dress some of the miniature birds featured in singing bird boxes? ¶
Q: Are feathers their pigmentation or iridescence? ¶

Q: Are feathers dyed and manipulated to enhance their appearance? ¶
A: Yes, as poultry feathers are naturally often dull in appearance compared to the feathers of wild birds.

A: Yes, and a bird's plumage weighs two or three times more than its skeleton, since many bones are hollow and contain air sacs.
Q: Are feathers also apparent in the families Troodontidae and Dromaeosauridae? ¶
Q: Were feathers observed to degrade more quickly under bacterial action? ¶
A: Yes, and even compared to unpigmented feathers from the same species, than those unpigmented or with carotenoid pigments.
Q: Are feathers fluffy because they lack barbicels? ¶
A: Yes, so the barbules float free of each other, allowing the down to trap air and provide excellent thermal insulation.
Q: Are feathers stiffened so as to work against the air in the downstroke but yield in other directions? ¶
Q: Are feathers saurischians? ¶
A: Yes, and however featherlike "filamentous integumentary structures" are also known from the ornithischians Tianyulong and Psittacosaurus.
Q: Are feathers believed to have evolved primarily in response to sexual selection? ¶
Q: Are feathers both soft and excellent at trapping heat? ¶
A: Yes, thus, they are sometimes used in high-class bedding, especially pillows, blankets, and mattresses.
Q: Were feathers more resistant? ¶
A: Yes, the authors cited other research also published in 2004 that stated increased melanin provided greater resistance.
Q: Are feathers not uniformly distributed on the skin of the bird except in some groups such as the penguins? ¶
A: Yes, and ratites and screamers.
Q: Are feathers vaned feathers? ¶
Q: Are feathers governed by the eagle feather law? ¶
