Ring-necked parakeets, originally from Africa and parts of Asia, have become a familiar sight in Paris over the past 50 years. These colorful birds, known for their distinctive neck rings and bright green plumage, first arrived in the Île-de-France region in 1974 when about 50 of them escaped from Orly airport. Another escape in the early 1990s at Roissy-Charles-de-Gaulle airport further boosted their population and genetic diversity, allowing them to thrive in the area. Today, the population of ring-necked parakeets in Île-de-France has grown dramatically—from around 1,000 birds in 2008 to nearly 15,000 individuals. This rapid growth is largely due to urban environments that provide warmth through "urban heat islands," easy access to food, and the feeding habits of Parisians who often provide snacks for the birds in parks and gardens. Organizations like the League for the Protection of Birds (LPO) and the European platform ParrotNet have documented these population figures. While the parakeets have adapted well to Parisian winters, thanks to their strong physiology and the urban environment’s features, their survival is also aided by human feeding. However, this practice has created competition for food and nesting sites, leading to the displacement of native bird species. The parakeets’ growing numbers and territorial behavior have raised ecological concerns, as they can outcompete local birds for resources. The spread of ring-necked parakeets has extended far beyond the original escape sites of Orly and Roissy. Today, they are found in the heart of Paris, as well as in cities like Lille, Nancy, Marseille, and Toulouse, and even in overseas territories such as Guadeloupe and Reunion. However, they have vanished from Mayotte, an island in the Indian Ocean. In response to these concerns, some local governments, including the Hauts-de-Seine department, have implemented bans on feeding parakeets in public spaces to reduce their impact on native wildlife. The ring-necked parakeet is now classified as an invasive exotic species of concern in France. Strict regulations are in place, including a ban on releasing captive parakeets into the wild. While these birds have become a symbol of urban life in France, their presence continues to spark debate about the balance between human activity and ecological preservation.
