Question

Tail feathers and wing feather of birds are known as
A)Filoplumes and contours
B)Rectrices and remiges
C)Remiges and rectrices
D)Contours and rectrices

Answer 1

The shed of their flight plumes can result and lead to the difficult issues for winged animals, as it can hinder their capacity to fly. Many different species have developed various methodologies for adapting to this, going from dropping all their flight quills without a moment's delay (and along these lines providing flightless for some generally brief timeframe) to broadening the shed over a time of quite a while.

Complete answer:
Flight plumes are observed as long, firm, lopsidedly molded, yet evenly matched pennaceous quills that can be known to exist on the wing and tail of a fowl. Those that are present on the wings are termed as remiges, while those on the tail are termed as the rectrices. The essential capacity of the flight plumes is to play a major role in the age of both pushes and lift, in this way empowering flight.

Flight quills (Pennae volatus) are shown as the long, firm, unevenly formed, evenly matched pennaceous plumes on the wings or tail of a fledgling; those on the wings are termed as remiges, particularly reflex. while those that are present on the tail are called rectrices, solitary rectrices. The flight plumes of certain winged creatures have advanced to carry out extra capacities, for the most part, that are linked with regional showcases, romance ceremonies, or taking care of techniques. In certain species, these quills have been developed into long garish tufts used in visual romance showcases, while in others they make a sound during show flights.

Hence, the correct answer is option (B)

Note: Small serrations on the main edge of their remiges play a major role for owls to fly quietly (and in this way chase all the more effectively), while the extra-solid rectrices of woodpeckers are needed for them to support against tree trunks as they hammer on them. indeed, even flightless fowls actually hold flight quills, however at times in profoundly adjusted structures.
