In my December article for Berkeley Hills Living, Montclair Living, and Piedmont Living magazines, I decided to focus on the Yellow-rumped Warbler and the idea that this one species may be split into several. Take a look!

I have been writing a monthly article for a set of three neighbor magazines for the past couple of years now. These magazines are distributed to a handful of east bay neighborhoods. I have shared one or two of the articles in previous posts, and am thinking of doing so more regularly, so here is the article on Phoebes that I wrote for the November issue of Berkeley Hills Living, Monclair Living, and Piedmont Living magazines.

What a day! What a day! What a day! The Drakes’ Beach Sanderlings participated again in the Rich Stallcup Bird-a-thon on October 5th. The Drake’s Beach Sanderlings, which is Point Blue Conservation Science’s longest running youth bird-a-thon team, was a bird finding machine! Thanks to our amazing donors, our team raised over $2,500 this year! To each of our sponsors, thank you so much for your support!

As usual, our day began very early. At 5:15am, and in the 39°F chill of the pre-dawn morning, we met at the Bear Valley Visitor Center. The sky was spectacularly clear which made for beautiful star-gazing but did not bode well for finding migrants later in the day. As soon as we got out of our cars, we realized we were surrounded by Great Horned Owls, and after a bit of listening, we added Spotted Owl to our list for the day! A good start!

The team stopped by Olema Marsh which irrupted in a cacophony of Virginia Rails as soon as we clapped for them! We then sped off to Five Brooks Pond where we tried to find more owls while it was still dark. As dawn approached, we were treated to a terrific mixed flock of Bushtits, both species of Kinglet, and lots and lots of Townsends Warblers. We then drove past Bolinas Lagoon and birded Stinson Beach.

Leaving Stinson Beach we broke into the Oreos and headed for the Outer Point! It was still early, and a quick overview of the species list showed that we had already found over 100 species by the time we reached the Outer Point! This put us ahead of schedule on both time and species.

Confirming our concerns from the morning, the clear skies the night before resulted in there being no vagrant birds anywhere on the Outer Point, though there were tons of Red-breasted Nuthatches. It was somewhat frustrating to find no unusual birds at Chimney Rock or Drake’s Beach, but we did not get too attached to birding the area and left to head east. We did stop at an overlook near Chimney Rock to find Black Oystercatchers and got to watch a pod of Humpbacked Whales feeding off the coast.

The team then started zig-zagging across the east half of the county picking up more bird species all along the way. We certainly had some ups and downs. We made some targeted stops for particular species that mostly worked in our favor. The ponds at the Las Gallinas Water Treatment Plant were the emptiest I have ever seen them, but a quick change of course to the Hamilton Wetlands was gangbusters! As usual, we ended at our customary final stop at an east San Rafael marsh where the Ridgeway’s Rails were calling before we even got out of the car!

Over the course of the day, the team moved incredibly efficiently. When a site was not producing the species we were hoping for, we quickly made decisions to abandon those stops and to go look elsewhere. The knowledge of all the team members came together to produce a cornucopia of species even though we did not find a single species that would be considered noteworthy for Marin County. The list we ended up with included 162 species as a group, and 2 more that were only seen by a single team member and so don’t quite count! The full list is on the next page. We all had an amazing day. We enjoyed every bird, ate a lot of cookies, and shared a lot of stories and knowledge. All the things that make the Sanderlings great!

I want to thank all those who supported this team. The Drake’s Beach Sanderlings is a very special group that I am honored to lead, and passionate to see continue. With the support of our sponsors, we all help promote bird conservation and climate science, and also something more. We help to show the role that young people can play. Bringing in funding in an event like this reminds the world, and the birding community in particular, that dedicated young birders can and do make significant contributions to the cause of protecting our world. I hope that all our sponsors return next year to support us again, and all those who did not sponsor us this year will consider joining the cause next year. I can’t wait!

Dear Sponsor,

The Drake’s Beach Sanderlings was the first, and is the longest running, youth Bird-a-thon team that the Point Reyes Bird Observatory has ever organized. I was one of the founding youth members and am now the team leader.

Since its beginning, the Sanderlings have established a very successful tradition of crisscrossing Marin County every fall, finding as many bird species as possible in twenty-four hours, and raising money for bird research and conservation. During the 2018 bird-a-thon, the Sanderlings were particularly successful when we found more bird species than any other team that year! Over the years our team members have changed as our youths get older, move away, or enter college. Wherever they have spread, Sanderlings members carry a passion for birds and nature with them that was, in part, nurtured by our team.

We are now preparing for our 2019 bird-a-thon! To support this team, I would like to invite you to become a sponsor of the Sanderlings. Your support sends a powerful message to the birding community that a team of young people can make an important contribution to bird conservation. This year, the Sanderlings bird-a-thon will be on October 5th. When you become a sponsor, I will be sure to let you know how the day goes.

Becoming a sponsor is easy! Just go to: https://pointblue.securesweet.com/contribute_paymentspring.asp?userid=1&fundid=832 and enter your info, or follow the QR code, below. I hope you are able to support this wonderful team. Please feel free to contact me with any questions you might have.

 

Sincerely,

Aaron

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.

Geographic range of the California Condor in the 1880s

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.
