What is Coccidiosis?

  • Coccidiosis is caused by single cell organisms Eimeria Labbeana & Eimeria Columbarum which affect the intestines of pigeons
  • This disease is most severe in young birds and is prevalent in warm, damp conditions and particularly  where there is poor hygiene or ventilation.
  • Infection can be spreak through any contaminated source and disease results when susceptible birds  (ie young birds or those that have not previously been protected) are exposed to higher numbers of parasites 

What is Canker?

  • Canker (Trichomoniasis) is caused by Trichomonas columbae which is a microscopic single celled organism.
  • It is the most comon form of infection in pigeons
  • Affects mainly the throat and crop but may include other parts of the body
  • The organism is usually transmitted by saliva so food and water are contaminated when feeding and drinking and this is passed to other birds through parental feeding of young or "billing" 
  • Youngsters are the most affected as they have not built up their natural immunity

Worms & Parasites

  • There are many worms & parasites that can affect pigeons, most commonly roundworm, hairworm & tapeworm
  • Roundworms & Hairworms live in the digestive tract  and release eggs which are passed in their droppings
  • These eggs can be ingested, become infectious after several days and hatch into new worms
  • There is no easy way to tell if your birds have these worms as the adult worms are only rarely passed in droppings and and Hairworms are vitually invisible to the human eye
  • Tapeworms also live in the digestive tract but have a head which embeds itself into the lining of the pigeon's bowel
  • Behind the head are segments (packets of eggs) which continue to form a long chain until the more mature ones eventually snap off and pass from the piegon's cloaca
  • The small ones look like white pieces of cottom trailing through the dropping, larger ones look like pieces of rice stuck to the surface of the dropping
  • These soon become part of the pigeon's food chain and continue the infestation cycle if left
