Cherry-head and red-masked parrots soared to fame with the release of the documentary “The Wild Parrots of Telegraph Hill.” Most San Francisco locals and tourists don’t know about the lower-profile, but equally spectacular flock of parrots (or parakeets, as they are also known) also roaming the foggy skies of the city by the bay.

That other flock are known collectively as the canary-winged and white-winged parakeets, according to Joe Morlan, ornithology instructor at City College of San Francisco. Morlan describes them as half the size and less colorful than the more notorious flame-colored parrots.

Not that anyone is looking for the canary and white-wings, if they stood out. The canary-wings inhabit the towering palm trees along a two-mile stretch of Dolores Street, a location that holds no draw for tourists seeking to experience the storied and postcard-worthy scenery of Telegraph Hill.

The canary-wings don’t even get to enjoy their patch of the city without having to make room for their celebrity counterparts they must avoid for their own safety.

“The Telegraph Hill flock is flying into canary-winged territory almost constantly,” said Mark Bittner, the former caretaker of the birds featured in “The Wild Parrots of Telegraph Hill” who now only makes occasional observations of the flock. “These flocks don’t mix at all. They’re territorial like all other animals in nature.”

The cherry-heads and red-masks have long encroached on the canary-wings’ territory even before they became famous. You could even say the cherry-heads stole the canary-wings’ spotlight in 1989 when a breeding pair of cherry-heads banished all the canary-wings from Telegraph Hill and never allowed their return, according to Bittner.

Relentless defense of prime scenery has caused trouble for the cherry-heads. In 2007, the San Francisco Board of Supervisors passed an ordinance to ban feeding of these birds in order to protect them from danger due to their rising popularity as a tourist attraction.

The canary-wings don’t need such protection. They freely feed on fruit in Noe Valley, Mission Dolores and Potrero Hill in relative peace from humans. Sometimes they go unrecognized in even high traffic areas such as Dolores Park.

“There are wild parrots here?” said Joe Fox, a Pacific Heights resident visiting Dolores Park. “I’m here almost everyday to walk the dogs, and I’ve never seen them around here.”

But for residents in neighborhoods near Dolores Street, the canary-wings are less anonymous thanks to their loud screeching.

“They come over to Duboce Park too. You can hear them going over the house, mostly in the morning,” says Chaylee Priete, an East Coast transplant living in Duboce Triangle for the past eleven years. “They don’t bother me. It’s exciting.”

Bird experts aren’t as enthusiastic about the wild parrots. According to Morlan, both flocks are believed to have been imported from South America by pet shop owners in the 1970s and were released into the wild by escaping or being released from owners who found the parrots too loud. Although the parrots have adapted to San Francisco’s climate and aren’t pests to local crops, Morlan says, “The ideal is that they should be in South America where they came from.”

“It’s political,” Bittner said. “A lot of people who study this, biologists, are highly opposed to them being non-native.”

With breeding having leveled off, there are about forty canary-wings flying around the city, roughly the same number as the cherry-head and red-mask flock. Even if the canary-wing population boomed, the low profile canary-wings may never capture the level of attention the Telegraph Hill parrots command. But at least the canary-wings have some supporters.

“So what if they’re not native? Most people in San Francisco aren’t.” Priete said.
