"Del Rey Hills colony"?
San Diego County, California, US
For many years there was a small population of these parakeets that lived and bred inside the Canary Island Palms at SDSU, estimated around a steady 20 birds. SDSU cut down the trees and the parakeets are still seen around but I am not sure where (if) they are now breeding.
Not a great shot, but it's a pretty bird. Introduced species here (escapees from the pet trade), very common as you get into hill country with some trees. (And yes, there's lots of eucalyptus. It was the answer to all sorts of questions, way back when.)
Feeding on Guava tree in residential area.
The Rose-ringed Parakeet (Psittacula krameri), also known as the Ring-necked Parakeet, is a gregarious tropical Afro-Asian parakeet species that has an extremely large range. Since the trend of the population appears to be increasing, the species was evaluated as Least Concern by IUCN in 2012.
