Advice and assistance with sick or injured wildlife can be provided by FAWNA, the Wildlife Helpline or your local vet.
Contact details and more information are provided below.
First stop for any injured bird should be a veterinary check, either dropping off directly or through FAWNA. If after hours then FAWNA often manages until getting to a vet.
Be very careful when dealing with an injured animal should you find one, particularly the larger birds and animals including owls and raptors. If in doubt, wait for professional help.
Note that the Biodiversity Conservation Act (BC Reg 124-6) anyone possessing fauna (not just taking it to a vet) is required to release it, give it to a wildlife officer or registered carer or report it to DBCA within 24 or 72 hours (depending on the conservation status of the species).
