I’ve found a BIRD
COMMON CAUSES FOR INTERVENTION
Cat attacks, orphans (spring storms and pruning), concussion (glass windows), secondary poisoning (from rodent baits, snail pellets and lawn beetle poison) and car accidents.
Any bird attacked by a cat will undoubtedly have unseen claw puncture wounds. Any wound inflicted by a cat can cause septicaemia which if left untreated will kill the animal within 48 hours. Although the bird may appear to be uninjured, please do not let it go as it will need treatment to survive.
