 West Nile Virus

West Nile virus is a flavivirus, closely related to St. Louis encephalitis. It is found in Africa, West Asia and the Middle East, and recently has begun to spread throughout North America.

WNV is spread by the bite of infected mosquitoes, and at this writing has infected more than 110 species in North America (including, amongst others, raptors, songbirds, waterfowl and game birds). Members of the corvid family (ravens, crows, jays and magpies) are especially susceptible to the virus.

Infected birds may exhibit symptoms such as malaise, ataxia, poor coordination, constricted pupils, anorexia, diarrhea, rapid respiration, salivation, inability to fly, distended crop, etc.

Some commonly seen infectious diseases of birds are:

 Bacterial Diseases

Bacterial

  • Avian Cholera (many species)
  • Botulism (especially ducks, game birds, shore birds, raptors)
  • Chlaymdiosis (psittacosis: psitticines and many other species)
  • Conjunctivitis ("finch conjunctivitis" especially in species that visit feeders)
  • E-Coli
  • Listeriosis (affects many species; raptors acquire it from infected prey)
  • Mycobacteriosis (Avian Tuberculosis: many species)
  • Pasteurellosis (especially birds that are caught by cats)
  • Salmonellosis
  • Spirochetosis (grouse, pheasants, turkeys, waterfowl)
  • Staphylococcosis
  • Streptococcosis
  • Ulcerative enteritis (Quail disease: bobwhite quail)
 Viral Diseases

Viral

  • Avian Pox
  • Avian Influenza (most birds)
  • Duck Plague (duck virus enteritis: herpes virus: ducks, geese, swans)
  • Paramyxoviruses (especially pigeons) and Newcastle Disease (avian pneumoencephalitis: many birds, including cormorants, pigeons)
  • Viral Hepatitis of Ducks (especially Mallard ducks); Viral Hepatitis of Geese
  • West Nile Virus (most birds, especially corvids)
    Fungal
  • Aflatoxicosis (toxin produced by the fungus Aspergillus flavus)
  • Aspergillosis (many birds, especially waterfowl and captive raptors)
  • Candidiasis (young birds, raptors; especially birds with crops, like doves)
 Parasitic Diseases

Parasitic

  • Capillaria
  • Coccidiosis
  • Flukes
  • Gapeworm
  • Giardiasis
  • Roundworm
  • Trichomoniasis
