SummaryThe response properties of a slowlyadapting mechanoreceptor located at the base of filoplumes in the feathered skin of the pigeon have been studied electrophysiologically. Both a strong dynamic component and an irregular firing rate and a cold-sensitivity show considerable similarity to the type SA I receptor in the mammalian skin whose morphological basis is a Merkel cell receptor. The functional characteristics have been studied with regard to excitation under natural conditions. The…

TLDR
Despite its very specialized function (bird flight) the somatotopic representation of the wing in the spinal dorsal horn is very similar to that of the forelimb of mammalian species.
Coding of vibration by neurones of the dorsal column nuclei in the pigeon
TLDR
Vibration sensitive neurones were most sensitive to 200 to 500 Hz, and tap-neurones were activated by sharp brief taps, and coding for vibration is represented in the nn.
Spinal dorsal column afferent fiber composition in the pigeon: an electrophysiological investigation
TLDR
The spinal dorsal column of homing pigeons was investigated electrophysiologically by recording responses from individual afferent fibers at a high cervical level to mechanical stimulation of wing skin and deep tissue to find slowly adapting responses to firm pressure or movements of limbs.
Functional role of airflow-sensing hairs on the bat wing.
TLDR
The present findings suggest that cortical neurons are specialized to monitor reverse airflow, indicating laminar airflow disruption (vorticity) that potentially destabilizes flight and leads to stall.
Biomechanics of the peafowl's crest: a potential mechanosensory role for feathers during social displays
TLDR
The results suggest that peafowl crests have properties that make them suitable mechanosensors for airborne stimuli generated during social displays, which could complement acoustic and visual perception, thereby enhancing the detection and interpretation of social displays.
Biomechanics of the peafowl’s crest reveals frequencies tuned to social displays
TLDR
It is demonstrated that peafowl crests have mechanical properties that allow them to respond to airborne stimuli at the frequencies typical of this species’ social displays, suggesting a new hypothesis that mechanosensory stimuli could complement acoustic and visual perception and/or proprioception of social displays in peAFowl and other bird species.

The biophysics of bird flight: functional relationships integrate aerodynamics, morphology, kinematics, muscles and sensors
TLDR
Research at the interface of the systems used in flight control is reviewed and several common themes are discussed, including wing velocity about the shoulder, shape within the wing, and angle of attack.
Filoplume morphology covaries with their companion primary suggesting that they are feather-specific sensors
TLDR
The morphology of filoplumes and their replacement schedule relative to their associated primary suggests that they are sensors, capable of detecting subtle differences in the position and movement of their companion feathers.

Temperature-sensitive mechanoreceptors, thermoreceptors and heat nociceptors in the feathered skin of pigeons
Summary1.Single unit recordings from afferent fibres of a cutaneous branch of the radial nerve were done during thermal stimulation of the skin of the wing with a thermode or with radiant heat or
Cutaneous Mechanoreceptors and Nociceptors
TLDR
Although information from sense organs is used by all animals, only man can verbally report his sensory experience, and neurophysiological experiments defining the properties of cutaneous sense organs have most often been done on animals other than man.
Neck flexion related activity of flight control muscles in the flow-stimulated pigeon
TLDR
It is assumed that there exist neck reflexes on wing and tail muscles which are ‘switched on’ when the pigeon is blown upon, and that these reflexes might act as a servo-mechanism which, as proposed by Groebbels (1929), causes the body to follow its beak during flight.

Morphological Criteria for the Differentiation of Mechanoreceptors in Vertebrates
TLDR
The structure of mechanosensory cells in invertebrates are primary sensory cells with a modified cilium as sensillum, which is principally different from the structure of Mechanoreceptors in vertebrates.
