Why Are Birds Dying Around My Bird Feeder? Understanding and Preventing Bird Mortality

The troubling sight of deceased birds near your bird feeder can be heartbreaking. The reasons why birds are dying around your bird feeder? can be multifaceted, ranging from disease outbreaks to poor hygiene practices; however, understanding these threats and implementing preventative measures is crucial to maintaining a healthy bird feeding environment.

Introduction: A Sanctuary Turned Problem?

Bird feeders offer a fantastic opportunity to connect with nature, observe fascinating behaviors, and supplement the diets of our avian neighbors. However, when not properly maintained, these seemingly beneficial resources can inadvertently contribute to disease transmission and other factors that cause bird deaths. Understanding the potential risks and taking proactive steps is paramount to ensuring that our bird feeders remain havens of health and enjoyment, not sources of harm.

The Benefits and Drawbacks of Bird Feeders

Bird feeders offer a vital food source, especially during harsh weather conditions or times when natural food sources are scarce. They also provide opportunities for education and enjoyment. However, concentrating birds in a small area can unfortunately amplify the spread of diseases and create unintended consequences.

• Benefits:

  • Supplemental food source
  • Wildlife observation opportunities
  • Educational value
  • Conservation support

• Drawbacks:

  • Disease transmission
  • Attracting predators
  • Dependency on human-provided food
  • Potential for nutritional imbalances

Common Causes of Bird Mortality at Feeders

Why are birds dying around my bird feeder? The causes are diverse and often interconnected. Here’s a look at some of the most common culprits:

• Salmonellosis: This bacterial infection is a frequent cause of bird mortality, especially in winter when birds congregate at feeders. Symptoms include lethargy, ruffled feathers, and diarrhea.
• Avian Pox: Characterized by wart-like lesions on the skin, particularly around the eyes, beak, and legs. It can interfere with feeding and vision.
• Trichomonosis (Frounce): A parasitic disease that causes lesions in the mouth and throat, making it difficult for birds to swallow.
• Aspergillosis: A fungal infection of the respiratory system, common in environments with poor ventilation and mold growth, which can be exacerbated by soiled feeders.
• Window Collisions: Birds attracted to feeders can collide with nearby windows, resulting in injuries or death.
• Predation: Feeders can attract predators such as cats, hawks, and other animals, increasing the risk of predation.
• Toxic Foods: Feeding birds moldy or otherwise unsuitable food can lead to illness and death.
• Pesticide Exposure: Birds might ingest pesticides directly from contaminated seed or insects near the feeder.

Preventing Disease Outbreaks: Hygiene is Key

Implementing strict hygiene practices is the single most effective way to minimize the risk of disease transmission at bird feeders.

• Regular Cleaning: Clean feeders and surrounding areas at least once every two weeks, and more frequently during periods of high bird activity or disease outbreaks.
• Disinfection: Use a solution of one part bleach to nine parts water to disinfect feeders. Rinse thoroughly and allow to air dry completely before refilling.
• Raking: Rake up spilled seed and bird droppings around the feeder regularly to prevent the build-up of bacteria and fungi.
• Rotation: Rotate feeders frequently, giving birds access to clean feeding areas while allowing previously used areas to dry out.
• Choose Appropriate Feeder Types: Tube feeders with small feeding ports are less likely to become contaminated than open platform feeders.
• Avoid Overfilling: Only fill feeders with enough seed that birds will consume in a few days to prevent spoilage.

Selecting Safe and Nutritious Bird Food

The type of food you offer can also impact bird health.

• Purchase High-Quality Seed: Choose fresh, dry seed from a reputable supplier. Avoid seed that is moldy, insect-infested, or dusty.
• Offer a Variety of Foods: A varied diet provides birds with the nutrients they need to stay healthy. Consider offering black oil sunflower seeds, nyjer seed, suet, and mealworms.
• Avoid Processed Foods: Avoid feeding birds processed foods such as bread, crackers, and chips, as these offer little nutritional value and can be harmful.
• Store Food Properly: Store bird seed in a cool, dry place in airtight containers to prevent spoilage and infestation.

Minimizing Window Collisions and Predation

Beyond disease, accidental deaths can be reduced by a few simple techniques:

• Window Treatments: Apply decals, window films, or screens to break up reflections and make windows more visible to birds.
• Feeder Placement: Position feeders close to windows (within 3 feet) or far away (more than 30 feet). Birds close to the window won’t gain enough momentum to hurt themselves, and birds far away won’t see the window as a continuation of their flight path.
• Provide Shelter: Plant trees and shrubs near the feeder to provide birds with cover from predators.
• Keep Cats Indoors: Cats are a major threat to birds. Keep cats indoors or provide them with a secure outdoor enclosure.

Reporting Sick or Dead Birds

If you observe sick or dead birds near your feeder, it’s essential to report your observations to your local wildlife agency or state department of natural resources. This helps track disease outbreaks and monitor bird populations. Remove feeders immediately if you suspect an outbreak of avian disease.

Recognizing the Symptoms

• Lethargy: Birds appear weak, inactive, and unresponsive.
• Fluffed Feathers: Birds may ruffle their feathers to try and stay warm.
• Difficulty Breathing: Birds may gasp for air or exhibit labored breathing.
• Discharge from Eyes or Nose: Runny eyes or nasal discharge can indicate infection.
• Swollen Eyes or Lesions: Look for any abnormal growths or sores.
• Diarrhea: Birds may have loose, watery droppings.
• Neurological Symptoms: Birds may exhibit head tremors, seizures, or an inability to fly.

Frequently Asked Questions (FAQs)

Why are so many birds dying this year compared to previous years?

• The number of birds dying at feeders can fluctuate from year to year due to a variety of factors, including weather patterns, disease outbreaks, and changes in bird populations. Some years are simply more conducive to the spread of certain diseases. Remember to keep a keen eye out and follow the guidelines above for safety.

Can I get sick from handling dead birds or contaminated bird feeders?

• While the risk of contracting a disease from handling dead birds or contaminated bird feeders is low, it is always a good idea to take precautions. Wear gloves when handling dead birds or cleaning feeders, and wash your hands thoroughly afterwards. Children should be supervised and instructed on proper hygiene practices.

What is the best way to dispose of a dead bird?

• The best way to dispose of a dead bird is to bury it in a deep hole or double-bag it and place it in the trash. Avoid handling the bird directly, and always wear gloves. Contact your local wildlife agency for specific guidelines in your area.

Should I stop feeding birds altogether if I see sick birds?

• It is generally recommended to take down your feeders temporarily if you observe sick birds to prevent the spread of disease. Clean and disinfect your feeders thoroughly before putting them back up. Monitor the situation closely and only resume feeding when you are confident that the outbreak has subsided.

Are certain bird species more susceptible to diseases at feeders?

• Yes, some bird species are more susceptible to certain diseases than others. For example, finches are particularly vulnerable to salmonellosis. Knowledge of the common diseases affecting species in your area can help you to tailor your monitoring and preventative efforts.
