Ring-necked Parakeet

Ring-necked Parakeet

Psittacula krameri
Ring-necked Parakeet, Sarah Kelman

Introduction

With its bright green plumage and rose-coloured neck ring, It is difficult to think of a more incongruous British breeding bird than the Ring-necked Parakeet.

The Ring-necked Parakeet was accepted onto the British List in 1983. It has long been a popular cage-bird and the British breeding population, currently estimated at around 12,000 pairs, is the result of birds escaping from captivity over a long period of time. The birds breeding here in Britain constitute the most northerly breeding parrots in the world.

With a population centred on the south-east of England, this is a regular visitor to bird tables, feeding on a variety of seed, nuts, fruit and fat cakes. BTO Garden BirdWatch results show that it uses gardens throughout the year but peaks during November and December.

Causes of Change and Solutions

Causes of change

Levels of breeding productivity are sufficient to account for the observed population increases, assuming mortality remains low.

Further information on causes of change

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 (Strubbe & Matthysen 2007, 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).

Information about conservation actions

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).

Not in the countryside please! Investigating UK residents’ perceptions of an introduced species, the ring-necked parakeet (Psittacula krameri)

Published: 2024

The Ring-necked Parakeet is a non-native species in Europe, with more than 90 established breeding populations across the continent, particularly in urban areas. The UK, and Greater London especially, is home to the largest of these non-native European populations. This study used an online survey to examine people’s perception of this species across the UK, and found that negative views of Ring-necked Parakeets are stronger in rural areas than in towns and cities.
