A recent report from London shows a hunter, who has posted a video demonstrating how to shoot them; using a fake bird painted like a parakeet, describing the pellets used and even practicing on a squirrel first that falls victim to a pellet as it takes interest in the hunters' bait he put out in his back garden. The fake bird decoy does entice wild parakeets to the bird-feeders, and the hunter does successfully shoot one down.The RSPB strictly advises that this is not the solution to this problem. Under the general licence, there are rights to shoot them under specific guidelines only if commercial crops or public health are at risk. If you cannot prove there is just cause for actions, you're not safe from prosecution. Shooting in this situation is very dangerous to public health in built up areas of London, it's too compact and it should be left to authorities to deal with in urban areas.
There's more than one species
Monk Parakeets, ring-necked parakeets' cousins native to forests of Brazil and Bolivia, are said to be causing mass destruction to electrical lines by building large nests upon them. These end up causing blackouts from the weight on the pylons and some have even caused fires. Even Defra has stated that they are a hazard to householders due to the droppings below their nests. It is not certain how they came to arrive to the UK but it's believed to be the same reason as the others; released from captivity. Humane methods have been in place since 2011 to remove these birds costing £260,000, despite the RSPB disagreeing that culling is necessary. Others say that threats to National infrastructure will only heighten with the increasing warmer climates in the future. The population of monk parakeets is now down to the last 50 birds.
