Did parrots cross the 101 Freeway? LA’s secluded nanday parakeets are now in Ventura County

You may know the sounds of parrots screeching pretty well. They’re now definitely part of L.A.'s soundscape, even though they're not native to Southern California and only started multiplying a few decades ago, thriving in our urban jungle.

Researchers at Occidental College, with the Free Flying Los Angeles Parrot Project, have been studying one species in particular to see how they’re adapting to life in the L.A. basin.

The standout parrot

About nine species of parrots, native to South and Central America, fly around the region, according to John McCormack, who’s the director and curator of the Moore Laboratory of Zoology at Occidental College.

He says it’s not clear how they got here. Urban legends say these birds are descendants of parrots that escaped the pet trade, or broke free from homes and aviaries. Regardless, they’ve stuck around.

One of those species is the nanday parakeet, which are known for their rich green bodies, with blue-tinged tails and wings, and dark heads. They showed up in the 1980s and roost in our native Sycamore trees. McCormack says over the years they’ve acted differently from other species.

Nanday parakeets eat fuzzy Sycamore balls instead of local fruits, like the loquats that other parrots love. They also don’t fly as far as nandays would typically do in their native habitats, which includes Brazil and Argentina, or as far as other parrots do here.

“ The nandays had not spread all over the city,” he said. “They’d remained pretty confined to the canyons around Malibu.”

McCormack says the conditions here are different than back home, so that left them with a question:  If they were able to make that switch to L.A. County, why have they not spread beyond Malibu? Only a small portion of their habitat was impacted by the Palisades Fire.

Flapping to new frontiers

One of the ideas the team investigated was whether the nanday parakeets stayed put because there weren’t any suitable habitats around.

At the time of their analysis, the team found multiple areas where nandays could potentially thrive but hadn’t been spotted in yet. That included a coastal-facing canyon near Fillmore, next to Thousand Oaks, with sycamores.

Then, during their research, they noticed something had changed in that area.

“Lo and behold, we see on iNaturalist that, in fact, there has been this little persisting block of them in the canyon,” he said.

A small group of nanday parakeets have been there for about six months — the first stable population above the 101. Brenda Ramirez, a  research technician on the project, says the community science observations on iNaturalist is what makes their work possible.

“People always get so excited about these birds, and so it’s really wonderful that they get included in our research,” she said.

It’s not clear how the nandays got to these canyons. There’s a possibility it could be a repeat of the past — the birds may have escaped or been released from somewhere nearby.

Or, it could be a sign of changing behavior. Historically, nandays have been reluctant to cross infrastructure like the 101 Freeway. (Maybe they took a page from L.A.’s departed legend, the mountain lion P-22?)

McCormack says it goes to show that if given enough time in the parrot world, interesting things can happen. Next, his team will look into the birds’ DNA to see if there are other signs parrots are adapting to urban life.
