In the following pages, we'll explore pigeon healthcare directly from the perspective of our team. Together, we'll uncover strategies for preventing pigeon diseases, with a focus on canker, to ensure the health and happiness of our avian companions.
Understanding Canker in Pigeons
Canker, scientifically known as Trichomoniasis, is a highly prevalent and significant disease in the pigeon world, affecting approximately 80 percent of pigeons globally. This disease is caused by a microscopic flagellate organism classified as a protozoan, with different strains like Trichomonas gallinae and Trichomonas columbae, each varying in their ability to cause disease.
According to G. D. Butcher, D.V.M., Ph.D. (1996), canker is a significant disease in the pigeon world. Trichomoniasis primarily occurs in warm climates or during warm weather but can strike pigeons at any time of the year, including commercial squab operations. Adult pigeons often carry these trichomonads without displaying symptoms, but when subjected to stress factors like concurrent diseases, parasitic infestations, or overbreeding, these organisms can multiply rapidly, turning a mild infection into a severe and life-threatening condition.
The disease's widespread occurrence poses a continuous threat to pigeon flocks, whether they are kept for racing, exhibition, squab production, or as pets. Pigeon enthusiasts and breeders must remain vigilant in managing and preventing Trichomoniasis due to its ubiquity and potential for rapid transmission.
Furthermore, the economic and ecological implications of canker in pigeons are notable. Infected pigeons may experience reduced productivity, leading to financial losses in commercial operations. Additionally, in the wild, pigeons play essential roles in various ecosystems, and diseases like canker can disrupt their populations, affecting biodiversity and ecological balance.
Symptoms of Canker
Canker, or Trichomoniasis, manifests with a range of symptoms in affected pigeons. These symptoms can vary in severity and presentation, and they typically involve both oral and physical manifestations. Here's an in-depth description of the symptoms:
Oral Symptoms:
​Oral Lesions | Canker often begins with the development of small, raised, and circumscribed lesions on the mucous membranes lining the oral cavity. These lesions may appear as slightly elevated areas, sometimes surrounded by a thin red border. |
Difficulty in Closing the Mouth | ​Pigeons with canker may have trouble closing their mouths due to the presence of lesions in the oral cavity. This can result in a persistent open-mouthed appearance. |
Drooling | Infected pigeons may drool due to the discomfort caused by oral lesions. This drooling can be noticeable and is often a sign of oral irritation. |
Swallowing Difficulties | Pigeons with canker may exhibit repeated swallowing movements. The discomfort and pain from oral lesions can make swallowing challenging. |
Watery Eyes | When canker lesions extend to affect the sinuses or the tissues around the eyes, pigeons may develop watery eyes. This can be a visible sign of the disease. |
Physical Symptoms:
Reduced Feeding | Infected pigeons often exhibit reduced feeding behavior. They may lose their appetite, resulting in weight loss over time. Lethargy Canker-infected pigeons may become lethargic and less active than usual. They may spend more time resting and show reduced interest in their surroundings. |
Weight Loss | Ongoing feeding difficulties and reduced food intake can lead to significant weight loss in pigeons with canker. This weight loss may be one of the most noticeable physical signs. |
Diarrhea | Some pigeons with canker may develop diarrhea, which can contribute to dehydration and further weight loss. |
Increased Water Intake | Infected pigeons may drink more water than usual, possibly as a response to dehydration caused by diarrhea or reduced food intake. |
Respiratory Distress | In severe cases, canker lesions can extend into the respiratory tract, leading to respiratory distress. Affected pigeons may exhibit labored breathing and open-mouthed breathing. |
Sudden Death | Particularly in severe cases where the lesion obstructs the trachea or causes significant debilitation, affected pigeons may succumb to the disease suddenly. |
Causes of Canker
Trichomoniasis, caused by Trichomonas gallinae and Trichomonas columbae, is a significant concern in the pigeon world, with a complex mode of transmission. The disease often spreads from bird to bird, primarily through contaminated feed and water sources. This transmission route occurs during the pigeons' routine feeding and drinking activities, where Trichomonas organisms from the mouth and nasal secretions of infected birds may enter shared food and water supplies, thereby contaminating them. When other birds consume from these contaminated sources, they become susceptible to infection.
Additionally, Trichomonas organisms are excreted in the feces of infected birds, adding another layer of potential contamination. Infected birds may defecate into shared food and water supplies, thereby introducing Trichomonas organisms that can infect subsequent birds that access these supplies.
A noteworthy insight, attributed to Racing Pigeon Laboratory Testing, underscores the risk posed by wild birds. Wild pigeons and other avian species can access domestic pigeon areas, contaminating food and water supplies with Trichomonas through their droppings. This serves as a reminder that maintaining biosecurity and preventing contact between wild and domestic birds is vital.
Furthermore, infected parent birds can transmit Trichomonas to their offspring through regurgitative feeding. This method is particularly relevant for pigeons, which produce a nutrient-rich secretion known as 'crop milk' and regurgitate it to nourish their young squabs. Regrettably, this nurturing act can also transfer Trichomonas organisms to the vulnerable squabs, emphasizing the importance of monitoring and managing the health of breeding pairs.
Raptors, including birds of prey, can also become infected with Trichomonas by preying on birds like doves and pigeons that carry the organism. The incubation period for raptors to develop overt infections after consuming an infected bird is approximately ten days.
Considering these insights, preventing Trichomoniasis requires a multifaceted approach. It involves not only maintaining clean and uncontaminated food and water supplies but also enforcing strict biosecurity measures to limit contact with wild birds. Additionally, careful monitoring of breeding pairs and proactive disease management can help mitigate the spread of Trichomonas among pigeon populations.
Contagiousness and Prevention
Canker is a highly contagious disease among pigeons. Understanding how it spreads and implementing preventive measures is crucial to safeguard pigeon populations.
Spread of Canker:
Direct Bird-to-Bird Contact: Canker primarily spreads through direct contact between infected and healthy pigeons. This can occur during grooming, mating, feeding, or other close interactions.
Feeding Young Squabs: Adult pigeons that are carriers of Trichomonads can transmit the disease to their young when regurgitating food into their mouths. This is a common mode of transmission, particularly in breeding pairs.
Contaminated Water and Food: Pigeons can contract canker by consuming contaminated food and water sources. Infected birds may contaminate communal feeding and drinking areas.
Vectors: External factors like insects and parasites can also play a role in transmitting Trichomonads between pigeons. These vectors may carry the parasites from one bird to another.
Preventive Measures:
Quarantine New Birds: When introducing new pigeons to an existing flock, isolate them for at least 30 days before introducing them to the main group. This quarantine period helps ensure that newcomers are free of disease.
Regular Depopulation and Cleaning: Periodically depopulating pigeon lofts and thoroughly cleaning and disinfecting the premises can help break the cycle of infection. Remove all bedding, droppings, and contaminated materials during cleaning.
Hygiene Measures: Practice high standards of hygiene by regularly cleaning feeding and drinking areas. Remove stagnant water sources that could become contaminated.
Treat or Remove Infected Birds: Identify and isolate infected pigeons promptly. If possible, treat them under the guidance of a veterinarian. Removing infected birds from the flock can prevent further spread.
Sanitation: Maintain clean, dry, and well-ventilated loft conditions. Regularly clean and disinfect food and water containers.
Limit Overcrowding: Overcrowding can create stress and increase the risk of disease transmission. Provide adequate space for pigeons to minimize stress factors.
Monitoring Health: Routinely monitor the health of your pigeons. Early detection of canker symptoms allows for swift action and containment.
Treatment: Although some previously effective drugs have been removed from the market, consult a veterinarian for available canker treatment options. Experimental treatments like copper sulfate, hydrochloric acid, or mercuric chloride may be worth investigating.
Natural Remedies
Preventing canker (Trichomoniasis) in pigeons is a critical aspect of maintaining their health and wellbeing. While traditional veterinary canker treatments remain the primary approach, some pigeon enthusiasts explore natural remedies as complementary or preventive measures.
One such remedy is Apple Cider Vinegar (ACV). Here, we discuss ACV and its potential benefits in preventing canker.
Apple Cider Vinegar (ACV)
ACV has gained popularity in pigeon husbandry due to its purported health benefits. It is rich in acetic acid, which has mild antibacterial and antifungal properties. While ACV alone may not be a cure for canker, it is considered by some as a potential preventive measure. Here are its potential benefits:
Digestive Health: ACV is believed to promote good digestive health in pigeons. A healthy digestive system can help pigeons better process their food, potentially reducing the risk of developing canker.
Balancing pH: ACV may help balance the pH levels in the crop and digestive tract. This balance can create an environment less conducive to the proliferation of Trichomonas organisms.
Immune Support: Some proponents of ACV suggest that it can boost the immune system in pigeons. A robust immune system can help pigeons resist infections, including Trichomoniasis. Using ACV to Prevent Canker: If you choose to use ACV as a preventive measure against canker in pigeons, here are some considerations:
Dilution: Mix ACV with water before administering it to pigeons. A common ratio is one to two tablespoons of ACV per gallon of drinking water. This dilution helps prevent potential irritation to the crop lining.
Frequency: You can offer the ACV-treated water to pigeons regularly, such as once or twice a week. Ensure that clean, fresh water is always available alongside the treated water.
Monitoring: Continue monitoring the health of your pigeons regularly. While ACV may have potential benefits, it is not a guaranteed preventive measure. Be vigilant for any signs of canker or other health issues.
Consultation: Always consult with a veterinarian who specializes in avian medicine before introducing any new supplements or remedies into your pigeons' diet. A professional can provide guidance tailored to your specific flock's needs.
Apple Cider Vinegar is sometimes used as a natural remedy in pigeon husbandry to potentially prevent canker, its effectiveness varies among individual birds and flocks. It should not replace proper veterinary care and hygiene practices. Combining natural remedies like ACV with sound management practices, regular health checks, and clean-living conditions can contribute to a holistic approach in preventing canker in pigeons.

Note: Always consult with a veterinarian experienced in avian health for specific guidance on loft treatment and care practices tailored to your flock's needs.
Pigeon Resistance to Canker
According to Pigeon Mania, pigeon canker can be influenced by genetic factors. Stress often triggers trichomonad growth in pigeons, leading to canker, particularly in weaker individuals. Genetic susceptibility to canker exists within certain pigeon families, prompting fanciers to routinely treat young birds for canker shortly after weaning.
Debates arise regarding treating mature birds for canker during egg incubation. Some argue against it, suggesting that older birds gradually introduce trichomonads to nestlings while feeding, aiding immunity development. Treating young birds just before their first races, when stress peaks, is an alternative approach. Pigeons unable to withstand this stress may not perform well and are often culled.
Beyond the genetic intricacies of canker resistance, pigeon fanciers must consider a holistic approach to maintaining a healthy flock. While genetic resistance is crucial, it's only one piece of the puzzle.
Frequent stressors, like racing or overcrowding, can strain even the hardiest pigeons' immunity, potentially compromising their resistance to canker. It's essential to strike a balance between genetic selection and managing stress levels.
Moreover, monitoring and adapting to your loft's unique dynamics is key. Pigeon health can vary widely based on environmental factors, including loft cleanliness, ventilation, and the presence of potential carriers like wild birds. Regular health checks can help identify vulnerabilities.
Lastly, while genetic selection can enhance canker resistance, remember that pigeons' genetic diversity also contributes to their overall resilience as a species. Inbreeding and excessive selection for a single trait can weaken the gene pool, potentially making pigeons more susceptible to other health issues. Maintaining genetic diversity, along with targeted selection for resistance, can ensure a healthier and more robust pigeon population.
In essence, while genetic factors play a significant role in canker resistance, a comprehensive approach encompassing stress management, loft hygiene, health monitoring, and genetic diversity preservation is vital for maintaining the long-term well-being of your cherished pigeon flocks.
