Indian ring-necked parakeet

What does it look like?

Indian ring-neck parrots are 38-42cm, typically with a green body. Colour variations are available due to selective breeding/mutation. Colours other than green usually cost more to buy. The neck is encircled by a red band (males) or indistinct emerald band (females). Males also have a black bib from underside of the beak down to the neck band and may have a bluish tinge on the back of the head. Sub-adult males are difficult to distinguish from females. Males become sexually mature and develop the neck ring at 2-3 years old. Lifespan in captivity is approximately 20 years (in some cases up to 34 years). It’s outgoing and feeds and breeds in groups.

This species has a broad climatic tolerance, ranging from cool and wet to hot and dry conditions, and has naturalised in at least 35 countries. Its likelihood of occurrence decreases with increasing frost days, while reproductive success is higher in warmer climates, such as the Mediterranean, than in cooler regions like the United Kingdom. It’s therefore likely to be able to acclimatise to New Zealand’s climatic conditions.

Why is it a problem?

Ring necked parakeets forage in groups, allowing them to dominate food sources. They are aggressive and can out compete native birds for nesting sites and will actively attack potential nest predators like rats.

Clutch sizes range from one to seven eggs, depending on cavity type. While some overseas populations produce two clutches per year, evidence from New Zealand suggests this is unlikely. Nestlings fledge at around seven weeks of age.

Overseas invasions show rapid population growth, with annual increases of 15-30 percent in the UK and around 22 percent in the Netherlands, although range expansion is slower. Breeding populations are closely associated with human settlements.

Ring necked parakeets are considered a horticultural and conservation pest and are listed as an Unwanted Organism under the Biosecurity Act. Introduced birds may also spread diseases such as Beak and Feather Disease, posing a risk to native species.

Control methods
