Perruche de Derby

One of the largest parakeets in the world, Lord Derby's parakeets display distinctive blue-green plumage with a striking red-and-black banded bill and a long pointed tail reaching over 60 cm. They inhabit montane forests at 1,000–4,000 meters elevation across the eastern Himalayas, southwest China, and northern Myanmar. Listed as Vulnerable due to deforestation and trapping, they are prized aviary birds. They are known to breed cooperatively with related pairs assisting dominant breeders.

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.
