Parakeets now outnumber native British birds after escaping into the wild
Parakeets have reached record numbers in the UK, outnumbering native species such as kingfishers, barn owls and lesser-spotted woodpeckers.
The birds first came to Britain as pets but some escaped into the wild and are now a common site in suburban South East England, particularly west London and Kent, although they have been as far north as Scotland.
While native woodland birds have suffered from climate change and loss of habitat, the tropical birds have thrived in warmer temperatures.
In the latest estimate, the British Trust for Ornithology (BTO) said the population has now reached a record 20,000, the majority of which are living in the South East.
Bedecked with emerald green feathers and a rose-red beak, the ring-neck parakeet was brought to the UK from India and was first reported in the wild in 1969.
By 1996, there were 1,500 of the birds living in the wild, by 2002 there were 6,000.
There are now more parakeets in England than kingfishers of which there are only 5,000 or lesser-spotted woodpeckers of which there are just 6,000.
John Tayleur, of the BTO, said: "Parakeets thrive on vast range of food: fruit such as pears, apples, cherries and grapes, as well as the berries of holly and and mistletoe, along with nuts, cereals, flowers and weed and tree seeds.
"They seem to get to these berries and seeds earlier than other species."
However this has caused concern among fruit farmers and seasonal traders. On the continent parakeets have been blamed for decimating crops. Mr Tayleur said parakeets were costing Painshill Park vineyard, near Cobham, Surrey, £5,000 a year in damage and bird-scaring devices.
There are also concerns about the effect on native species. Scientific studies show parakeets lead to a fall in the population of nuthatches and there are concerns for willow tits and woodpeckers that compete with the tropical birds for nesting space.
However, conservations say that since the population is confined to a particular area, there is no need for a cull.
Recent figures from the RSPB show some species of woodland birds, many of which would compete directly with parakeets, have declined in recent years. For example number of willow tits have fallen 77 per cent decline since the census started in 1994.
Graham Madge of the RSPB, said parakeets probably now outnumber around 50 species of birds in the UK. He explained that parakeets, that nest earlier, can deprive other birds of space as well as food. He said there was no need to cull the population because the birds are still confined to particular areas around in the South East. However the RSPB will be keeping an eye on the situation.
"There are a large number of birds which are now outnumbered by parakeets such as kingfishers, barn owls and red kites. But that is not to say they are declining because of parakeets."
He added: "On the evidence we have so far there is nothing to suggest parakeets are causing a problem for native birds because they are confined to a small range. But there may be concern if they they become much more widespread."
The Government is currently developing a framework for dealing with non-native species - such as the parakeets, Chinese mitten crabs and grey squirrels - and assessing the impact on native species to these shores.
