If you stroll through London’s parks and green spaces during summer, you might hear a loud, distinctive squawk that belongs to an exotic visitor: the feral rose-ringed parakeet. These vibrant green parrots, with males bearing a striking red ring around their neck, have established thriving colonies across London, especially in areas like Central London, Kingston Upon Thames, Richmond, Twickenham, Catford, and Battersea. Feral parrots are an extraordinary example of non-native species adapting to urban environments and have become a unique, if sometimes controversial, part of London's wildlife.
The most commonly observed feral parrots in London belong to the species rose-ringed parakeets (Psittacula krameri), native to parts of South Asia and North Africa. Adult birds typically measure about 40cm including long tail feathers, and they are known for their piercing squawks and ability to mimic human speech. Alongside them, monk parakeets have also been spotted in smaller numbers. These similar but sturdier birds feature a white chest and are known for building extensive large nests in trees or bushes, sometimes spanning several feet across.
The exact origin of London’s feral parrots is uncertain and widely debated. It’s generally accepted that their colonies began from escaped or released pet birds during the late 20th century. Some theories include a single breeding pair released into the wild, an aviary collapse during the 1987 storms, a container spill at Heathrow Airport, or escapes from filming studios in London. The rose-ringed parakeet population alone is now estimated to be over 30,000 birds, having grown rapidly since the 1990s. Monk parakeet populations are smaller but expanding.
Despite their tropical origins, rose-ringed parakeets display remarkable resilience to colder UK winters, though harsh winters can reduce their numbers naturally. They feed opportunistically on berries, seeds, nuts, buds, vegetables, and fruits, sometimes leading to significant damage to local orchards and gardens. Their successful adaptation is due to their flexible diet, ability to nest in urban trees and structures, and social nature.
Introducing non-native species like parakeets into the local ecosystem can disrupt native wildlife. These parrots compete with native birds for food resources, often taking food intended for smaller species and potentially excluding them from habitats. Their rapid breeding and growing populations pose challenges to biodiversity. To manage this, agricultural controls and population management strategies are underway. DEFRA has planned control measures including culling for monk parakeets to prevent further ecological imbalance.
Parakeets are most visible during warmer months when their loud calls echo through trees. London offers several hotspots to witness these charismatic birds up close, including:
Visitors should enjoy these sightings responsibly, appreciating the beauty of these birds while respecting local ecosystems.
London’s feral parrots show how wildlife can adapt to urban environments. Their presence provokes important discussions around invasive species management, conservation, and coexistence. Whether you're an admirer of their vibrant energy or concerned about their impact, recognising the balance between protecting native species and appreciating urban biodiversity is crucial for responsible stewardship.
