Concerns have been raised by Hazel
Jackson, an expert in invasive species and conservation at the University of Kent, over the impact of the growing numbers of rose-ringed parakeets in south-east England. Scientific research programmes have analysed the behaviour of parakeets and found that they

The numbers remained very low, however, until the mid-1990s, when the population appeared to start increasing rapidly. The population was estimated at 500 birds in 1983, reached 1,500 by 1996, and 5,800 in the London area in 2002 (sheltering in up to 5 roosts). The last official roost

Despite the increase in notability and population size at the end of the 20th and beginning of the 21st centuries, escaped parakeets have been spotted in
