WHITTIER – Over the past few years, David Kornblum has noticed the increasingly tropical tone of the local bird chorus outside his Uptown Whittier home. The sounds come from an apparently growing population of Red-crowned parrots who have made his neighborhood around Palm Park their home, he said. With a plentiful supply of tall maple and pine trees available, the birds have a perfect canopy to call home. Kornblum said at least 40 parrots now settle in for the evenings in a two-block area near Palm Park. During the day the parrots fly off in search of food – the typical parrot schedule. Kimball L. Garrett, ornithology collections manager for the Natural History Museum of Los Angeles County, said he has had many calls from residents and local bird watchers about the growing parrot population. But while Garret suspects the anecdotal reports may be correct, it is very difficult to prove definitively. “It’s a little tough to distinguish between a true population increase and birds moving from one area to another, and it depends on the species,” said Garrett, who is also founder of the California Parrot Project. Garrett said a “couple thousand” parrots have thrived in the San Gabriel Valley and it’s possible some of those have spread south, or birds from a large Orange County population could be spreading north. But since the San Gabriel group has successfully nested for years, Garrett said it’s probable that the perceived increase in the Whittier parrots is real. “[The parrots] may have just been successful at population recruitment – reproduction in the wild,” he said. “The birds you see are not all the result of escapes.”165Let’s talk business.Catch up on the business news closest to you with our daily newsletter.

You’re all set! “They’ve been around for a while but they’ve increased recently,” said Kornblum, 46. “It’s quite something to see a whole flock of these tropical birds flying by.” He said he has noticed the birds in his neighborhood for about five years. “Here are these big green and red parrots, the kind you see in a pet store, and there they are just sitting in the trees near my home,” Kornblum said. Although parrots are known for being noisy – especially in large flocks – Kornblum said it didn’t bother him. “The tropical tones compliment the bird song,” he added.
