What happens if you feed a pigeon bread?

Pigeons are a common sight in cities around the world. Many people enjoy feeding pigeons bread crumbs or pieces of bread. But is bread actually good for pigeons? Here is a look at what happens when you feed pigeons bread.

Can pigeons eat bread?

The short answer is yes, pigeons can eat bread. Pigeons are omnivores and eat a variety of foods, including bread, cereal grains, seeds, fruits, and even garbage or scraps. So bread is not toxic or immediately harmful to pigeons.

Bread is a good source of carbohydrates and calories for pigeons. The main concern with feeding bread to pigeons is that bread lacks the protein and fat content that pigeons need in their diet. Bread is considered a “junk food” for pigeons.

Nutritional impacts of bread

While bread will not cause pigeons to become ill right away, a diet heavy in bread can lead to nutritional deficiencies or problems over time. Here are some of the nutritional impacts of eating too much bread:

  • Lack of protein – Bread does not contain much protein, which pigeons need to build muscle and feathers. Without adequate protein, pigeons may have poor muscle tone or damaged feathers.
  • Lack of vitamins and minerals – Bread is not a good source of important vitamins and minerals like calcium, vitamin D, and others. Pigeons need these nutrients to maintain their immune system and organ function.
  • Poor chick health – Adult pigeons eating excessive bread may produce chicks that have low birth weight or poor feather growth due to nutritional deficiencies.
  • Obesity – Bread is very high in carbohydrates but low in other nutrients. Pigeons that fill up on bread may become overweight or obese.
  • Fatty liver disease – Excess carbohydrates from bread must be converted to fat in a pigeon’s liver. This can lead to liver damage over time.

In moderation, bread is okay as an occasional treat for pigeons. But relying on bread as a main food source can lead to long-term health consequences.

Dangers of molds and contaminants

Bread that sits outside quickly becomes moldy or contaminated with bacteria, fungi, or other pathogens. Pigeons that eat moldy bread run the risk of developing:

  • Mycotoxicosis – Illness caused by ingesting dangerous mycotoxins produced by molds
  • Aspergillosis – Respiratory illness caused by inhaling Aspergillus fungal spores on moldy bread
  • Salmonella, E. coli, or other bacterial infections from contaminated bread
  • Illness from pesticides, insecticides, or other chemicals that contaminated the grains used to produce the bread

Rotting bread also attracts rats and other vermin that can spread diseases to pigeons and people. Stale bread can harbor cigarette butts, bits of broken glass, or other debris that can injure pigeons when ingested.

Impacts on behavior

Feeding pigeons bread can also change their behavior, especially when large groups congregate to be fed. Problems associated with regularly feeding flocks of pigeons bread include:

  • Dependency – Pigeons may become dependent on human handouts and lose their natural foraging ability.
  • Loss of migration – Well-fed urban flocks may abandon migration patterns.
  • Displacement of native species – An abundant pigeon population monopolizes food resources needed by other local wildlife.
  • Aggressive behavior – Large pigeon flocks may become aggressive towards each other or even people when competing for handouts.
  • Messy defecation – Large pigeon flocks produce abundant droppings on buildings, sidewalks, cars, etc.

In some cities, pigeon overpopulation and aggressive behavior have become a public nuisance leading to culling programs. Responsibly moderating pigeon feeding helps prevent these issues.

Health risks to humans

Excessive numbers of pigeons drawn to an area by feeding also pose health risks to humans, including:

  • Histoplasmosis – Caused by fungal spores in dried bird droppings.
  • Cryptococcosis – Caused by fungal yeast in droppings.
  • Psittacosis – Bacterial disease transmissible to humans.
  • Toxoplasmosis – Protozoan parasite carried by some pigeons.
  • Bird mites – Mites that bite humans when carrier bird populations decline.
  • Slipping hazard – Droppings make sidewalks slippery.

Pigeon droppings also damage property by corroding building materials. Reasonable population control via limited feeding helps reduce health and safety risks.

Alternative foods for pigeons

For those who enjoy feeding pigeons, there are several healthier food alternatives to bread. Some better options include:

Food Benefits
Cracked corn, barley, oats High in carbohydrates for energy and fatty acids for warmth during winter.
Peas, lima beans, soybeans Excellent protein source for strong muscles and feathers.
Finely chopped dark leafy greens Provide vitamins, minerals, and carotenoids for immune health.
Chopped hard boiled eggs Good source of protein and fat.
Birdseed mix Formulated to deliver balanced nutrition.

A varied diet will provide pigeons with a much more complete nutritional profile compared to just bread. This helps support their health and keeps city flocks sustainable.

Healthy feeding practices

When feeding pigeons, keep these tips in mind for their health and yours:

  • Feed in moderation – Large amounts attract vermin and cause dependency.
  • Use healthy foods like seeds – Avoid only providing “junk” like bread.
  • Clean up uneaten food – Prevents rotting or molding.
  • Don’t touch dead birds – Use gloves and disinfectant.
  • Wash hands afterwards – Reduces disease transmission.
  • Follow local ordinances – Many prohibit or limit feeding.

Consider joining with community groups to install approved pigeon feeding stations designed to be cleaned regularly. This concentrates pigeons away from high traffic areas.


Feeding pigeons bread won’t kill them, but it lacks good nutrition. Bread is best as an occasional treat, not a dietary staple. While many love feeding pigeons, excess bread causes overpopulation, disease, and nuisance issues in cities. Seeking balance through moderate, healthy feeding practices allows enjoyment of urban wildlife while also sustaining healthy pigeon and human populations.
