compensatory behavior such as oculomotor, gaze, and postural responses that occur during movement largely depend upon a functioning vestibular system. in the present study, the initial loss and subsequent recovery of postural and head stability in pigeons ...

pigeons are a problem causing lots of mess and damage to property. we take a look at some pigeon facts and how these nuisance birds affect humans.
some birds bob their heads backwards and forwards as they walk. why? as they are descended from dinosaurs, would two-legged ones like tyrannosaurus rex have done the same?
ever wonder why pigeons have iridescent feathers? the feathers contain tilted latticework of tiny threads of pigmented material. learn more here.
stabilization of the head in animals with limited capacity to move their eyes is key to maintain a stable image on the retina. in many birds, including pigeons, a prominent example for the important role of head stabilization is the characteristic head-bobbing behavior observed during walking. multi …
the question : ‘why do some*(see note below) birds bob their heads when walking?’ has perplexed scientists for many years. some researchers suggest that head-bobbing may be correlated with the morp…
we’ve all seen them do it. but why?
as an adult, i’ve seen enough pigeons just take their mannerisms for granted. they just do pigeony-stuff because they’re pigeons, right? but today my kindergartner was watching some bobble along the sidewalk and asked “why do they walk like that?” it turns out it’s to help them see. everyone who’s moved their camera while the […]
wait- so dinosaurs might have bobbed and weaved their head like birds when they walk? man dinosaurs as we know them just get more and more fascinating! (i like thinking of a rex walking like a...

is it possible to stop birds doing that goofy thing with their heads when they walk?

answer (1 of 3): based on research studies, the definitive answer was inconclusive. it is known that doves (including the rock dove pigeon) have extremely poor eyesight. by constantly bobbing their heads, they are better able to discern shapes and objects, including food. there is actually a thru...
i had a older friend who had only one good eye. he would – automatically – “bob” his head before reaching out to contact something like a proffered hand, to “scan” for a 3-d location… and, he was unaware that he did this. when shown a video of the action, he was astonished! perhaps pigeons also employ this method to locate, given their “side-mounted” eyes? and, one has to wonder, are they aware of this, or do they really care…?
head and eye movements were simultaneously recorded during locomotory and pecking behavior of 4 pigeons (columba livia), which were trained to traverse a conditioning chamber, with a pecking key and a food dispenser at each end. head and eye movements were simultaneously recorded during locomotory and pecking behavior of 4 pigeons (columba livia), which were trained to traverse a conditioning chamber, with a pecking key and a food dispenser at each end. each trial involved key pecking, walking, and feeding. head movements were registered with a skull-mounted miniature accelerometer, and eye movements were recorded with implanted electrooculographic electrodes. an almost perfect temporal coordination between head and eye movements was observed during both walking and feeding bouts. during walking, head movements primarily provide retinal image stability, and eye movements support visual scanning. during feeding, head movements mainly subserve the grasping of food items, and eye movements maintain visual fixation on them. because the eyes are reflexively closed during the middle phase of pecks, the head and eye movements are then under ballistic control. the peculiar saltatory head motions that many birds exhibit while they walk have repeatedly attracted interest in the past. as early as 1930, dunlap and mowrer reported that although the body of locomoting chickens, pigeons, and starlings moves forward relatively smoothly, the head is held still and only thrust forward at intervals. this implies a succession of rapid forward and slower backward movements of the head with respect to the body. some authors have also drawn attention to a coordination between leg stepping and head bobbing (bangert, 1960; daanje, 1951). a related gazestabilizing response, that is, head nystagmus, occurs when these birds are exposed to a rotating visual environment (file, 1968; frost, 1978; fukuda, 1951; gioanni, 1988a; simon, 1954). a purely vestibularly driven head nystagmus has been demonstrated in pigeons (gioanni, 1988b; huizinga & meulen, 1951). however, friedman (1975b) and frost (1978) have concluded after examining the head motions of doves and pigeons in various experimental situations that the retinal image slip associated with locomotion is the principal stimulus that steers the rhythmic head bobbing (see also davies & green, 1988). these movements are so prominent that the occurrence of eye movements in birds was virtually overlooked for a long time. although benjamins and huizinga (1927), and later nye (1968), noted the presence of eye movements in pigeons, such movements have only been described in any detail during the past decade. it is now well established that the movements can amount to 20° or more, particularly in the hori
most evidence suggests that the head bobbing serves a visual function. chickens bob their heads while walking. so do cranes, magpies and quails. in fact, head bobbing is a unique feature in birds and occurs in at least 8 of the 27 families of birds. there are a few theories why some birds bob their […]
pigeons bob their heads while walking to help stabilize their surroundings as they process visual information.

birds, like chickens and pigeons, bob their heads so the world won't be a blur when they walk.
