Birds do not have teeth. Without teeth, a bird cannot chew its food down to bits in its mouth like humans do. As detailed in the textbook Ornithology by Frank B. Gill, birds must instead rely on the muscular stomach-like pouch called the gizzard to crush down their food. Many species swallow stones and grit to aid in digestion. These stones remain in the gizzard and crush the food as the gizzard contracts. From a functional perspective, gizzard stones in birds are the equivalent of teeth in humans. When a gizzard stone becomes too smooth to do its job, the bird regurgitates the stone or passes the stone down and out through its digestive tract. Species that do not swallow stones are able to use the sheer muscle power of their gizzards to grind down their food. Birds do not have teeth because the teeth and the jaw bone to support them are too heavy for efficient flight. Many birds have a series of notches in their beak or spikes on the inside of their beak or tongue. These notches and spikes are not true teeth as they are not used to crush down their food. Instead, these features are used to get a good grip on the prey so that it does not escape. In ancient evolutionary history, there were birds with true teeth. Known as odontornithes, these animals are no longer alive today.

It has long been recognized that birds possess the ability to use the Earth’s magnetic field for their navigation, although just how this is done has not yet been clarified. However, the discovery of iron-containing structures in the beaks of homing pigeons in a new study1 by Gerta Fleissner and her colleagues at the University of Frankfurt offers a promising insight into this complex topic. The article will be published online mid-March in Springer’s journal Naturwissenschaften.
In histological and physicochemical examinations in collaboration with HASYLAB, the synchrotron laboratories based in Hamburg, Germany, iron-containing subcellular particles of maghemite and magnetite were found in sensory dendrites² of the skin lining the upper beak of homing pigeons. This research project found that these dendrites are arranged in a complex three-dimensional pattern with different spatial orientation designed to analyze the three components of the magnetic field vector separately. They react to the Earth’s external magnetic field in a very sensitive and specific manner, thus acting as a three-axis magnetometer.
The study suggests that the birds sense the magnetic field independent of their motion and posture and thus can identify their geographical position.
The researchers further believe that this ability is not unique to homing pigeons as they expect that the ‘pigeon-type receptor system … might turn out to be a universal feature of all birds’. Equally, this concept might not only exclusively apply to birds, since it has been shown that many animals display behavior that is modified or controlled by the Earth’s magnetic field.
The meaning of these minute iron oxide crystals goes farther than their amazing ability to help pigeons home. Research into how they work has caught the interest of nanotechnologists concerning their potential application for accurate drug targeting and even as a data storage device. The main problem, however, lies in their synthetic production. According to Gerta Fleissner and her colleagues, “Even though birds have been producing these particles for millions of years, the main problem for scientists who want to find benefits from their use will be the technical production of these particles”.

The theory that pigeons’ famous skill at navigation is down to iron-rich nerve cells in their beaks has been disproved by a new study published in Nature.
The study shows that iron-rich cells in the pigeon beak are in fact specialised white blood cells, called macrophages. This finding, which shatters the established dogma, puts the field back on course as the search for magnetic cells continues.
“The mystery of how animals detect magnetic fields has just got more mysterious” said Dr David Keays who led the study.
Dr Keays continued: “We had hoped to find magnetic nerve cells, but unexpectedly we found thousands of macrophages, each filled with tiny balls of iron.”
Macrophages are a type of white blood cell that play a vital role in defending against infection and re-cycling iron from red blood cells. They’re unlikely to be involved in magnetic sensing as they are not excitable cells and cannot produce electrical signals which could be registered by neurons and therefore influence the pigeon’s behaviour.
Dr Keays’s lab, based at the Institute of Molecular Pathology in Vienna, worked together with Dr Shaw from the University of Western Australia, and Drs Lythgoe and Riegler from the UCL Centre for Advanced Biomedical Imaging in London.
“We employed state-of-the-art imaging techniques to visualise and map the location of iron-filled cells in the pigeon beak” said Dr Mark Lythgoe.
The search for the actual mechanism that allows migratory birds, and many other animals, to respond to the Earth’s magnetic field and navigate around their environment remains an intriguing puzzle to be solved.
“We have no idea how big the puzzle is or what the picture looks like, but today we’ve been able to remove those pieces that just didn’t fit,” said Dr Keays.

Photographs, especially of humans, are widely used as stimuli in behavioural research with pigeons. Despite their abundant use, it is not clear to what extent pigeons perceive photographs as representing three-dimensional objects. To address this question, we trained 16 pigeons to identify individual, real-life humans. This discrimination depended primarily on visual cues from the heads of the persons. Subsequently, the pigeons were shown photographs of these individuals to test for transfer to a two-dimensional representation. Successful identification of a three-dimensional person did not facilitate learning of the corresponding photographs. These results demonstrate limitations of cross-recognition of complex objects and their photographs in pigeons.

If you could ask any animal ‘A penny for your thoughts’, which would you choose? When the question occurred to Fumihiro Kano from Kyoto University, Japan, he decided to focus on the great apes. ‘Eye movement is a good indicator of attention, cognition and emotion’, he says, explaining how he uses an infrared eye tracker to monitor ape eye movements to understand their thought processes. However, after a decade, Kano decided to switch from working with apes to investigating the minds of homing pigeons through their eyes. Bird eyes are almost fixed in their sockets, allowing Kano to infer where they are gazing from the movements of their heads alone. Teaming up with fellow primate biologist – Dora Biro from the University of Oxford, UK, who also has a passion for researching pigeon navigation – Kano set about designing a head sensor that would allow him to measure the birds’ head movements to test how they use their eyes while homing through the Oxfordshire countryside.
Combining a GPS tracker, microcomputer and battery in a pigeon-sized backpack, Kano added an inertial measurement unit, which could track the bird’s head movements using a gyroscope and accelerometers, mounted on a custom-built mask. ‘Constructing the mask was actually the most challenging, but most fun, part of this study’, smiles Kano, who frequently visited the local craft store in Oxford to try out different materials until he had perfected the wire, felt and elastic band design. ‘The most important thing was to design the mask so that it did not interfere with the bird’s breathing when flying’, he recalls, adding, ‘Most of them were okay to wear it, but some of them didn’t seem to like it and immediately took it off, so we continued to modify the design until they were comfortable’. Once Kano, James Walker, Takao Sasaki and Biro were confident that the pigeons were content to fly wearing their new accessories, the team drove the birds 4 km up the road and then released them individually for the 10 min flight home.
Downloading the data after each bird returned, the team was delighted to see every detail of the head manoeuvres, in addition to the GPS plot of the return flight path. The first thing that they noticed was how stable the birds’ heads were; ‘it is like a high spec gimbal’, says Kano, describing how the heads of the animals barely wobbled. It was also clear that the pigeons were actively glancing from side to side, scanning the landscape, during their solo flights; ‘[They] moved their heads far more than necessary for manoeuvring flight’, says Kano. In addition, the birds reduced their head movements when approaching landmarks, including a main road and a railway line, ‘which indicates that they indeed “see” them to navigate’, says Kano. Finally, the scientists dispatched the birds in pairs to learn more about how they use their eyes when flocking, and noticed that the birds reined in their head movements when flying with a partner, ‘indicating that the flock-mate is a key visual cue that they need to pay attention to’, he says.
It seems that pigeons keenly observe their surroundings, especially when flying solo, and the team is eager to incorporate a tiny camera into the sensor to get a true bird’s-eye view of the world, with the hope of eventually taking a glimpse into the minds of other bird species.

Getting rid of pigeons on your own isn’t easy. These pest birds have an inbred homing instinct that makes them feel attached to their established roosting and nesting sites. Plus, mating pairs can hatch as many as four broods a year, so a small pigeon problem can quickly turn into a disaster. Pigeons will resort to laying eggs on bare surfaces if need be, so getting rid of pigeons isn’t as simple as removing their nests. Fortunately, Bird Barrier offers a number of high-quality pigeon control products that can effectively resolve any type of pigeon problem.
Problems Caused by Pigeons Sitting and Nesting
Pigeons are the most common type of pest bird in North America and they cause a variety of problems at all kinds of buildings, from airports to manufacturing facilities to power plants and the rooftops of stores, offices, and homes. Because pigeon droppings contain uric acid, which is highly corrosive, pigeons can cause a great deal of damage in a short amount of time. Feral pigeons are responsible for untold millions of dollars of damage each year in urban areas. Here are a few of the other most common pigeon roosting problems (and reasons why people need effective pigeon deterrents):
- Pigeons (and pigeon waste) can hurt the image of a business or commercial enterprise as they leave a bad impression
- Collected debris from roosting pigeon flocks can cause water damage by blocking up gutters and drains
- Roosting pigeons often cause extensive damage to air conditioning units and other rooftop machinery
- Droppings create hazardous surfaces that lead to slip and fall liability
- Bacteria, fungal agents, and ectoparasites found in pigeon droppings can pose a health risk.

Pigeon Control Solutions: Pigeon Spikes, Netting, Birth Control and More
Because pigeon prevention can be easier than pigeon removal, we at Bird Barrier always recommend proactive use of deterrent products that will cause these birds to roost elsewhere, so their homing instinct isn’t bringing them back to your property!
If you already have a flock of pigeons on your property, the first line of defense, as with all pest birds, is removing all sources of food and water from the site. However, you will need to take additional steps to control an established pigeon problem. Bird Barrier offers a number of solutions to deter and repel pigeons, from pigeon spikes to exclusion netting to birth control and beyond. With the right pigeon control products, you can solve any pigeon problem for good.
How to Select the Right Pigeon Deterrents For Any Situation
The most effective approaches to pigeon control and prevention include:
- Exclusion Netting
- Electric Shock
- Spikes, Optical Gel, Coil
- Pigeon Reproductive Control
- Audio, Visual, and Taste Deterrents
