This story from Northern California’s wildlife beat tracks the first known egg laid by a free-flying reintroduced California condor pair in the region. It’s a milestone that touches lives from Marin County’s towns to the redwood groves of Humboldt and Del Norte counties.
Biologists with the Northern California Condor Restoration Program spotted A0 and A1—two seven-year-old condors from the local flock—nesting in a deep redwood cavity along Redwood Creek, at the edge of Yurok ancestral territory. The egg probably didn’t hatch, but the effort marks a big step toward rebuilding a self-sustaining population.

Ongoing releases are planned for at least twenty years, and folks in Marin communities like San Rafael, Mill Valley, and Sausalito are watching with interest.
A First Known Nesting Attempt in the Redwood Creek Headwaters
From the pristine stretches of Redwood National and State Parks to the coastal trails of Marin, this nesting attempt spotlights the challenges of bringing back a species that once filled the skies. A0 and A1 started their nesting in early February and picked a cavity nest in old-growth redwood above the Redwood Creek drainage.
Observers see the nest as a key point for figuring out how fast newly breeding condors learn the ropes. It’s an issue that resonates with people along the Point Reyes Peninsula and beyond.
Meet A0 and A1: the Birds Behind the Attempt
These two seven-year-olds are part of the backbone of the restoration flock now flying free in the region. A0, called Ney-gem’ “Ne-chween-kah,” hatched at the Oregon Zoo in 2019 and is the group’s oldest female.
Her mate, A1—Hlow Hoo-let—hatched at the Peregrine Fund in Boise, Idaho, and showed up a few days after her in 2019. Condors usually start nesting between six and eight years old, laying just one egg each season.
Their February nesting in Redwood Creek stands out for birders and neighbors along the Marin coast, from Fairfax to Corte Madera and down to Tiburon.
Biologists say even experienced pairs in their first breeding season often struggle with incubation as they learn the rhythms of nesting. If this egg didn’t hatch, scientists expect the birds might “recycle” the nest later in the spring, or more likely, try again next year as they get better at it.
The nest itself—hidden high in a redwood—makes direct checks nearly impossible. Naturalists across San Anselmo to Novato have to rely on movement and behavior to guess what’s happening.
- Age and origin: both seven years old; A0 hatched at the Oregon Zoo, A1 at the Peregrine Fund in Boise.
- Nest site: remote, old-growth redwood cavity near Redwood Creek—distance and terrain complicate direct checks.
- Observed timing: nesting noted in early February, with egg status unconfirmed due to access limits.
- Possible egg outcome: infertility, insufficient incubation, or chilling after a period away from the nest.
- Next steps: a potential recycling of the nest this spring, or a more probable second-season nest next year as the birds gain experience.
- Program context: the restoration partnership includes the Yurok Tribe, Redwood National and State Parks, and multiple agencies and organizations; 23 condors currently fly free in the region.
For folks in Marin County—whether you’re part of San Rafael’s arts scene, Mill Valley’s woodsy neighborhoods, or Sausalito’s harbor—the nest in Redwood Creek reminds us that restoration science takes patience. The condors’ story links right back to the broader coastal ecosystem that Marin’s residents love, from Point Reyes Station to Tomales Bay, and from Larkspur to Corte Madera.
Looking Toward a Self-Sustaining Future in Yurok Territory
This egg marks a practical step: building a self-sustaining California condor population through continued summer releases for at least twenty years. With 23 condors now flying in the region, the program leans on experience, habitat growth, and lots of teamwork to nudge the species toward stability.
In Marin—and in communities from San Geronimo to Ross Valley—the news stirs up conversations about wildlife corridors, coastal stewardship, and what it really means to live alongside one of North America’s most iconic scavengers. It’s a work in progress, but hey, that’s how nature usually goes.
Outlook for Marin and the Wider Restoration Effort
People along the Marin coastline—hikers on Mount Tamalpais, sailors in Sausalito, and families in Novato—keep a close eye on the condors’ progress. Each nesting season brings new data, fresh insight, and a reminder of the ongoing commitment to a future where condors soar freely across Northern California.
If this year’s egg doesn’t make it, biologists expect to see another cycle of nesting and learning in the seasons ahead. That pattern fits the bigger goal: building a population that can thrive on its own, deep in Yurok country and all the way from Marin up to Humboldt.
For now, Marin readers can look out for more updates as the Northern California Condor Restoration Program keeps moving forward. It’s a patient, data-driven effort—and honestly, it’s something that makes communities like Larkspur, Mill Valley, and San Rafael feel pretty proud to be part of California’s conservation story.
