In 1982, the year I was born, there were only 22 California Condors alive in the world. Those 22 birds were all that remained of a population that once spanned the western US, and bits of Canada and Mexico. The Condor population plummeted as a result of lead poisoning, hunting, habitat loss and pollution.

By 1987, the world population of California Condors was 27 birds. Since the causes of the California Condor decline were distinctly human activities, it only seemed appropriate for humans to step up and attempt to fix what they had broken. To that end, the 27 birds were captured and taken into a captive breeding program run by the U.S. Fish and Wildlife Service. The goal of that captive breeding program was to first raise Condors and establish multiple captive breeding populations, and then to establish multiple wild populations. It was an ambitious plan.

Over the last 37 years, the program has overcome countless challenges from figuring out how to hatch condor eggs, to how to raise babies that will grow into wild adults, to teaching those young adults to find food. California Condors are not fast breeders. A pair will only lay one egg each year, and they sometimes skip years. The young birds take several years to grow and gain full independence, and will begin to breed after about five years. It has taken extensive amounts of money and time, but success after success have become realities.

A small number of captive breeding populations were established in zoos raptor breeding facilities. In 1992, Condors began to be released into the wild. Additional releases established small populations in California, Arizona, Utah, and Mexico.

Now a new milestone has been reached. In March of this year, the 1000th California Condor chick has hatched since 1987 when the captive breeding population was initiated. This brings the living population to around 500 individuals, since numerous chicks, juveniles, and adults have died in the last 37 years. The 1000th chick hatched in the wild to a pair of Condors living in Zion National Park in Utah.

A population of 500 individuals is still not big enough to be out of danger of extinction, and as such are still protected by the U.S. Endangered Species Act. But it is certainly a wonderful accomplishment, and the 1000th chick born is also a occasion to be celebrated. Hopefully, the California Condor population will continue to grow, and the amazing birds, the largest in North America, with their 9 foot wingspans will be circling 15,000 feet over our heads in greater numbers and across greater areas as the next 37 years unfold.

I spent the 4th of July weekend camping with my family at one of my favorite spots. Domingo Spring in Lassen National Forest. I first visited this site during my graduate school work where I was recording the calls of Evening Grosbeaks, and I have returned regularly ever since. The campground, set among jumbled piles of volcanic rocks and large conifer trees, is immediately beside a wet meadow that Domingo Creek runs through. Near the entrance of the campground is the source of Domingo Creek, and the campground’s namesake, Domingo Spring. This spring is one of the few places I know of where one can drink right out of the land. In my mind, that makes this a very special spot, indeed. We also drove to Willow Lake for part of one day which was lovely. Willow Lake has a floating sphagnum bog where a couple of native species of carnivorous plants grow wild.

The days we spent camping were filled with birds, a lake visit, walks throughout the surrounding meadows, lots of cooking over the fire, singing, talking politics, reading the Declaration of Independence on the 4th of July, drawing, and so much more! One bird encounter that was really wonderful was our neighbors in the campground. A pair of Cassin’s Vireos had a nest about 25 feet up a ponderosa pine tree at the edge of our campsite where four nestlings eagerly gobbled down each of the insects their parents delivered. Many Western Tanagers, including a lot of newly fledged birds, were also around this year.

The full species list for birds included: Mallard, Common Nighthawk, Anna’s Hummingbird, Turkey Vulture, Great Horned Owl, Black-backed Woodpecker, Hairy Woodpecker, White-headed Woodpecker, Pileated Woodpecker, Northern Flicker, Western Wood-Pewee, Stellar’s Jay, Common Raven, Tree Swallow, Mountain Chickadee, Red-breasted Nuthatch, Brown Creeper, House Wren, American Robin, Cassin’s Vireo, Evening Grosbeak, Purple Finch, Cassin’s Finch, Song Sparrow, Lincoln’s Sparrow, Red-winged Blackbird, Orange-crowned Warbler, MacGillivray’s Warbler, and Western Tanager.

We also had some nice herpetological encounters. I caught a small Mountain Gartersnake, and my wife and daughter caught a Pacific Tree Frog. Oddly, we did not see any gartersnakes are Willow Lake. In the past we have often seen them swimming in the lake as they hunt for minnows in the water, sometimes around our feet. This year, the water was much more turbid that it usually is (a result of the fairly recent snow melt?), and maybe this made the water less appealing as hunting grounds for the snakes that are pretty visual predators.

Mammals we saw included Mule Deer, California Groundsquirrel, Golden-mantled Groundsquirrel, Douglas Squirrel, and Allen’s Chipmunk.

I very much look forward to the next time I return to Domingo Spring to enjoy the mountains and drink from the rocks.
