Parakeet sightings in cities signal climate change shifts

Parakeets, especially ring-necked parakeets (Psittacula krameri), are increasingly seen in urban areas. Scientists say their spread reflects climate change, biodiversity shifts, and habitat change. They thrive in warmer cities due to food availability, milder winters, and the urban heat island effect, and are used as bioindicators of ecosystem health, though they may compete with native birds.
