Perruche à collier

One of the world's most widespread and invasive parrots, rose-ringed parakeets are native to Sub-Saharan Africa and South Asia but have established large feral populations in over 35 countries across Europe, North America, Japan, and Australia following cage bird escapes. Males bear a distinctive pink-and-black neck ring. Highly adaptable and prolific, urban populations have exploded in cities like London, Amsterdam, and Brussels, where they roost in enormous flocks and compete with native cavity-nesting birds.
