The Parapara Berry Tree
Scientific Name: Pisonia brunoniana, also known as: Birdcatcher Tree. The Parapara tree can also come in a variegated variety.
This tree is a death trap for birds, in the autumn/winter after flowering it emits a very sticky substance which ensnares birds and leads to their death. Cats and other wildlife are also victims. It is generally small birds that stick to the tree, larger birds fall to the ground disabled and get “lost” in the ground litter. The seed pods feed to the ground and ground feeders like blackbirds and thrushes also become entangled in the fallen pods. This tree is hazardous from February through to October.
What can you do? If you find birds caught up in the tree, do not cut any of the birds feathers. Cut off the branch/twig and bring the birds to your nearest bird rescue centre.
How to stop the problem? Some people cut the trees out. A less effective way is to remove the pods from the tree following flowering or cover the whole tree in bird netting when flowering. The problem can be remembering to do this each year.
Unfortunately garden centres are selling these trees as ornamental garden/house plants. They often do not display warnings of the dangers of this tree to our wildlife. Contacting your local council and/or garden centre to voice your opinion with this death trap is a step in the right direction of getting rid of this tree from our area.
Fishing Equipment
Fishing equipment is a huge problem for seabirds, hooks become embedded in beaks, legs, flesh or mouth and can be swallowed. Nylon gets tangled around legs, beaks and body. This leads to birds being unable to feed, fly or walk and cuts off circulation leading to the loss of a leg or foot and eventual death if left untreated. If you spot hooks or nylon lying around please pick it up and dispose of it – you could be saving a life!
Plastic Rings
Plastic rings from milk and cream bottles and other drink containers are a real danger as they get caught around the beak or neck and restrict or totally stop food intake. Ducks are the main species affected by this. We urge you to pick these up if you spot them. It is a good practice to get into cutting the ring in half after removing it from a bottle.
Cotton, String, Tape and Human Hair
Like plastic rings and fishing equipment, cotton, string, tape and human hair pose great danger for birds. It can become caught around the beak causes feeding problems and leading to starvation and death. When caught around the legs or body the bird can become entangled in trees and unable to free themselves. Restricted circulation results in loss of toes, feet or whole legs.
Plastic Bags
Birds caught up in plastic supermarket bags are in great danger as they are unable to fly or get away from predators. Seabirds swallow plastic bags thinking it is food and die.
Botulism
Botulism is caused by build up of toxins in fresh waterways. The toxins have a paralytic effect resulting in birds being unable to hold their heads up. The birds become very ill and need to be taken to a rescue centre immediately. We urge the public to feed birds on the grassed areas beside waterways (rather than in the water) as bread is a big contributor to toxin build-up in the water. Wetting the bread is also a good idea otherwise ducks will carry it to the water to feed.
Oil Pollution
Oil pollution is devastating to birdlife, the sticky oil clings on to the feathers resulting in hypothermia, the inability to fly and leaving them susceptible to oil toxicity and poisoning.
Overhead Cables
Unfortunately birds don’t understand the dangers of power lines. If you spot a bird hanging from a power line, please call the power company and report it to the SPCA.
Pigeon Spikes
Steel spikes that can be used as a deterrent for pigeons on rooftops around Auckland have become a death trap! While thought to be a humane solution, they have been seen to lead to a slow painful death for birds who are unlucky enough to become victim to the sharp spikes. There are nylon alternatives available in the United States which are much safer for birdlife.
Pruning
Pruning causes a threat to nesting birds especially during the spring. We encourage everyone to carefully check for nests before pruning their trees.
Road Kill
While hitting birds is not always avoidable, please do stop to see if the birds needs help. In the case of ducks, it pays to check if there are any ducklings nearby.
Windows/Garden Mirrors
Be aware that if your house doesn’t have curtains, birds can fly straight into windows when they see the view on the other side – sometimes breaking the windows and often killing themselves. Mirrors in gardens create similar problems. Please check to see if the bird needs a safe place to recover.
Cats and Dogs
The use of a small bell on a cat or dog collar is a good precaution against catching birds. The bells need only be used in the spring/summer as they are often annoying to the cat. Cats can be trained from an early age not to catch birds. Dogs left loose often kill birds without their owner knowing.
Jet Skis
Jet skis exceeding the speed limit (which is 5 knots within 200m of the shore) can have disastrous consequences for birdlife.
Slug Bait and Garden Sprays
Slug bait is a killer for birds. Quash is the safest option for birds and is what we recommend. However, if using other slug baits they can be put in a pipe or under an upturned ice cream container that has a small “entrance” cut out.
Pesticide garden sprays used when birds are nesting may affect the development of young birds resulting in parts of wings or legs missing or other deformities.
