Habitat & Geographic Range

Pacific Spiny-rat

Habitat

Typically found in diverse terrestrial and aquatic ecosystems.

Range

Found in Ecuador. Listed as Near Threatened, this species requires ongoing monitoring to prevent population decline.

Rose-ringed Parakeet

Habitat

Inhabits deserts and xeric shrublands within the Afrotropic biogeographic realm. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Africa (8 countries), Asia (21 countries), Europe (18 countries), North America (4 countries), and South America (Colombia, Ecuador, Venezuela).

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.
