Common Bird Parasites & Diseases

 

The four diseases that most frequently affect birds that use feeders are: salmonella, trichomoniasis, aspergillosis, and avian pox. All of these diseases are transmitted from one bird to another at feeding stations, especially when overcrowding occurs. Birds are also susceptible to mites and lice. There are many steps you can take to help keep feeder birds and people safe and healthy.

Common Diseases

Salmonella

The most common disease of feeder birds, Salmonellosis is caused by bacteria from the genus Salmonella and often begins as an intestinal-tract infection. Symptoms such as diarrhea, ruffled feathers, and lethargy usually occur. Birds who are showing symptoms usually die in 1 to 3 days.

The disease can spread rapidly at crowded feeding stations as healthy birds eat food contaminated by the droppings of sick birds. Salmonella can be transmitted to people who handle sick or dead birds; always wear disposable gloves when handling infected birds. And wash hands thoroughly after touching a bird feeder or birdbath.
