Question

The___
is a balancing organ of birds.​

Answer 1

Answer:

Uniquely among living animals, birds appear to have two specialized balance-sensing organs: the vestibular system of the inner ear and an additional balance sensor located between the hips called the lumbosacral organ (LSO) (Necker, 2006) which has been proposed to be especially useful for terrestrial locomotion

Answer 2

The lumbosacral organ is a balancing organ of birds.​

• Birds have a vestibular system in addition to the lumbosacral organ, a special balance-sensing organ located in the pelvis (LSO). In terrestrial birds, the LSO is well developed, probably to help with balance control during perching and terrestrial mobility.
• The LSO's functional advantages for balance have not been evaluated in any prior research. We propose that reduced sensorimotor delay and enhanced prediction of foot-ground acceleration are the two key advantages of hip-localized balancing sense.
• The idea that a hip-localized balance sense, which is closer to the feet than a head-localized sense, provides better estimations of foot acceleration was put to the test using system identification.

Hence, The lumbosacral organ is a balancing organ of birds.​
