If YOU start out facing forward and turn your head as far to the side as your head will go, most people can turn their heads about 90 degrees. A human's maximum range of rotation from side to side is more like a measly 180 degrees.
The bob is actually an illusion, scientists discovered in an experiment. The birds are simply moving their heads, allowing their vision to stabilize so their bodies can catch up, and then they're on the move again. This happens so quickly, it appears as though they're using a constant bobbing motion.
The hawk's ability to rotate its head was amazing. At times, it would rotate its head close to 180 degrees. The largest movement that the hawk would make always happened just before it flies to a new location, which involved using its beak to “scratch†or preen its chest feathers.

The sense of smell is the weakest in birds because they have very few olfactory receptors in their brain, but yet again few birds have a high degree of olfactory receptors, like the scavenging birds like vultures which can smell the dead meat from miles.
There is only one insect that can turn its head – the praying mantis.
Between 160 to 180 degrees; i.e. you should be able to rotate your neck to the right and to the left, so that your nose is in line with your shoulder (or near enough). The neck moves a heavy 4 to 5kg weight, around several axes of movement.
Three-toed sloths have extra vertebrae at the bottom of their neck, they can therefore turn their head a whole 270°, equipping them with an almost 360° view of their surroundings.
A hippo can almost open its mouth at 180 degress — that's wide! They use their strong mouth and teeth whenever they feel threatened. Hippos attack humans who enter their territory or get too close to their young.
Bones in owls' necks also have adaptations designed to facilitate extreme rotation. One of the major arteries feeding the birds' brains passes through holes in the vertebrae, called transverse foramine; the team found that these holes were 10 times larger in diameter than the artery.
Because owls have eyes at the front of their heads, they have a smaller field of vision – around 150 degrees for a barn owl (though they can turn their heads very far to look around). Parrots, pigeons and other birds with eyes on the sides of their heads have a much bigger field of vision, of about 300 degrees.
According to the Guinness World Records, the animal that can rotate its head the furthest is the tarsier. The singular spinal structure of the animals allows them to rotate their heads about 180° on either side of the head.
A 'stooping' peregrine is undoubtedly the fastest flying bird, reaching speeds of up 200 mph.
The owl can rotate its neck backwards to a large extent.
Flightless birds are birds which cannot fly. They rely on their ability to run or swim, and have evolved from their flying ancestors. There are about 60 species living today, the best known being the ostrich, emu, cassowary, rhea, kiwi, and penguin.
Most owls are nocturnal, meaning they are most active at night. Like many animals, owls have three eyelids. The upper eyelid closes downward when the owl blinks. The lower eyelid closes up when the owl sleeps.
Owls Require a PermitOwls are wildlife species, and you will need to be trained before you get a license to keep a native species in captivity. Only after being trained and licensed can you legally keep an owl. A "pet" owl is usually one being kept illegally.
Owls have a binocular vision of 70 degrees and they cannot move their eyes, but they can move their head an impressive 270 degrees. So in total, they can see a mile away for 270 degrees around themselves without moving their body.
Owls have large eyes and a flat face. Owls can turn their heads as much as 270 degrees. Owls are farsighted, meaning they can't see things close to their eyes clearly. Owls are very quiet in flight compared to other birds of prey.
A male pigeon courts his mate by bowing, cooing, inflating his throat, and strutting in a circle around the female. The pair may preen one another and the male may grasp the female's bill, regurgitating food as a courtship gesture.
Birds, like chickens and pigeons, bob their heads so the world won't be a blur when they walk. What the head bobbing lets pigeons do is momentarily fixate their eyes on objects. This gives the photoreceptors in their eyes enough time—about 20 milliseconds—to build a steady scene of the sidewalk world.
Pigeon Kissing is also known as “billingâ€. Kissing is part of pigeons' courtship rituals. The hen will often approach her mate and when he opens his beak he will feed her some semi-digested seed. They may then rub their beaks together.
Bowing and Turning: When a male is first looking for a mate, he'll show off by puffing up his neck feathers, bowing down in front of her, and turning around. Tail Dragging: Males puff up their neck feathers and drag their tail feathers on the ground, trying to impress nearby females.
It's in the eyesMost birds, unlike humans and other mammals, have their eyes placed on either side of their head. So to perceive depth, birds hack around it and do something interesting. They look the object for a while, move a bit, and then again swiftly turn their neck to see the object again.
Spivack believed he was initially photographing two birds grooming each other until the male jumped onto the back of the female. As it happens, males will often stand on the backs of females to signal that they are ready to mate. In females, the cloaca holds an organ housing the ovaries.
Tail flipping and wagging generally signal happiness, while tail fanning is a sign of aggression. If your bird is bobbing his tail, it may mean he is out of breath.
Are pigeons intelligent? Pigeons are considered to be one of the most intelligent birds on the planet and able to undertake tasks previously thought to be the sole preserve of humans and primates. The pigeon can also recognise all 26 letters of the English language as well as being able to conceptualise.
Well, its tail feathers are analogous to the rudders of ships and boats. They help them steer and maneuver while flying, as well as provide stability as they take-off and land. By twisting its tail, the bird can change its direction mid-flight.
