This form of Newcastle disease has been associated with parrots, cockatiels and other exotic birds. It is CFIA's responsibility to investigate and recommend action when mortality due to Newcastle disease is suspected. Newcastle Disease in Other Birds Many wild and pet birds including cormorants, pelicans, wild turkeys, parrots and cockatiels can carry Newcastle virus. On many occasions in the previous 10 years, mortality due to the Newcastle virus has been observed in waterfowl in Manitoba and Saskatchewan. Cormorants have been particularly affected.
Sick birds can be lame, have drooping wings, unable to fly and walk in circles.
The infected birds appear to lose some of their natural fear of humans. The virus can be shed in droppings and manure from infected birds and it can also travel as airborne particles. It is preserved by cold temperatures but may be destroyed by direct sunlight. The treatments for these diseases are not all the same and an accurate diagnosis is needed. In vaccinated birds, Newcastle disease may appear very similar to a bronchitis challenge in your flock.
