The Wild Parrots of Los Angeles

Home away from home:

For example, the driest month in Southern California is significantly drier than any portion of their native habitats in the western and eastern coastal regions of Mexico, the study says. The timing of the precipitation here is also different, with a winter rainfall regime rather than summer rains.

That “urban oasis effect” created by sprinkler watering systems “could partly explain why introduced parrots do not seem to be spreading beyond urban centers,” it says. “Their intelligence and behavioral plasticity might further allow them to adapt to urban life.”

The look of Southern California’s green canopies has changed significantly since the 1950s and ’60s, when developers turned up their noses at native oaks and sycamores. They chose instead to landscape their subdivisions, apartment complexes, business parks, shopping centers and roadways with nonnative trees, including sweet gums, camphor, carrotwood, fig, and ficus trees — all favored by parrots. 

For reasons that are not fully understood, several hundred parrots seek evening accommodations each night in the limbs of fig and London plane trees lining a bustling stretch of Rosemead Boulevard in Temple City. The odd locale is believed to be one of the most populous roosting sites for parrots in the Los Angeles area.
