Ring-necked Parakeet (2024)

Following escapes and releases over many decades, this parrot, native to Africa and southern Asia, began breeding annually in the UK in 1969. Substantial but highly localised self-sustaining populations have since built up, with the two largest being in Greater London and in the Isle of Thanet, east Kent. Genetic modelling has traced the origin of these birds, brought here initially by the cagebird trade, to the northerly parts of the native range in Pakistan and northern India (Jackson et al. 2015).

Population modelling in the early 2000s revealed that populations in Greater London initially increased by approximately 30% per year, and those in Thanet by 15% per year, but that the range initially expanded by only 0.4 km per year in the Greater London area and hardly at all in Thanet (Butler 2003). National BBS data indicate more than a tenfold increase since 1995, and more substantial range expansion has occurred, particularly in Greater London (Balmer et al. 2013). There have been recent post-breeding estimates of more than 30,000 birds at large in the UK (). There are concerns about possible environmental and economic effects of the Ring-necked Parakeet population.

From 108 nests located during 2001-03, the mean first-egg date was 26 March, median clutch size was 4, and overall nest success 72%, making productivity sufficient to account for the observed population rise, assuming mortality rates remained low (Butler et al. 2013).

The species has already been reported causing economic damage to crops, as has occurred elsewhere in its native and introduced range (Butler 2003). A recent study in Belgium has identified negative effects on breeding Nuthatch, but not on other native hole-nesting species, such as Starling (, 2009, Strubbe et al. 2010). No such effects have yet been detected in Britain, however (Newson et al. 2011). A Spanish study reported that the species had caused the decline of Noctule Bats in a Seville park, with parakeets observed attacking bats to gain access to nest holes (Hernandez-Brito et al. 2018). There is also evidence that the presence of parakeets reduces feeding rates among native birds (Peck et al. 2014), with a study using video recording in Paris suggesting that Starling was most impacted (Le Louarn et al. 2016).

As a non-native introduced breeding species, this species does not have a conservation status in the UK and hence is not a species of conservation concern.

On the contrary, there are concerns about the potential future impact of increasing parakeet numbers on other species, which could mean that conservation action to control parakeets could possibly be required in the future in order to protect native species (see Causes of Change section, above).
