In London a tree recently attracted attention for a surprising phenomenon: at first glance it appears to be covered in fresh, dense leaves, but in reality it is home to hundreds of ringed parakeets. These birds, known by the scientific name Psittacula krameri, come from Africa and southern Asia, but have adapted to British urban life for decades. Their bright green livery blends perfectly with the foliage, creating the illusion of an incredibly lush tree.

A natural and visual phenomenon
The scene is not only striking, but also symbolic of nature’s ability to infiltrate cities. The birds often gather in large flocks, especially at dusk, to rest together. The density of birds in the trees can be such that the plant itself appears to grow further in a single night.
The images of these flocks, often shared on social media, create a surreal effect, making the trees appear as if they had magically bloomed green. This behavior has recently attracted the attention of London residents, especially near car parks and urban parks, where the presence of these colonies can be particularly evident.

The impact on the urban ecosystem
Although charming, non-native parakeets pose some challenges. Their habit of feeding on spring flowers, particularly cherry blossoms, can shorten the flowering season, reducing the time that plants show their buds. They are also known for their intense noise, rapid spread and their often aggressive behavior towards food, which can create discomfort for both other animals and humans.
Adaptation and longevity
These birds display remarkable intelligence and social ability, which has allowed them to survive and thrive in London’s climate. They can live up to 30 years in the wild, forming stable colonies in different areas of the city. Their presence has now transformed some urban areas into living landscapes, where the boundary between vegetation and fauna becomes almost imperceptible.
