Advisory: Dead Birds Under Examination
Testing is underway on several dead birds that washed
ashore on the Avalon and Bonavista Peninsulas since March 22. The Animal
Health Division of the Department of Natural Resources will examine the
birds to determine official cause of death. At this point, starvation
has been noted in a number of the birds examined.
Approximately 45 dead birds have been collected to
date with more expected to come ashore. Officials with the Animal Health
Division and Environment Canada�s Canadian Wildlife Service will
continue to monitor the situation. Recovery of further birds from
Bonavista and elsewhere on the Avalon is underway.
People are asked not to touch the birds and to keep
pets from coming into contact with them. Please be advised that no one
should be picking up these birds unless they have, or are covered to do
so by, a migratory bird permit issued by Environment Canada�s Canadian
Wildlife Service.
At this time of year, bird die-offs are not an
uncommon event due to ice, weather conditions and starvation. Previous
die-offs have been associated with fungal infections, pesticide spills
and avian cholera, a bacterial disease common in wild birds with minimal
risk to humans.
The department has also examined several dead gulls,
primarily of the great black-backed and glaucous species, recently found
in the area of Quidi Vidi Lake. Toxicology reports indicate no evidence
of common pesticides. However, the gulls did exhibit high concentrations
of caffeine in their stomachs. This is now considered to be the likely
cause of death.
