a few weeks ago, i had the pleasure to accompany some friends and dedicated raptor-enthusiasts to see a bald eagle nest in alameda county that had two newly fledged juveniles. bald eagles have been slow to return to the Bay Area, and there are only about 16 nests currently in the vicinity from Monterey up to Mendocino County. a good sign to see them coming back.
they were comical to watch – flying was fairly easy, but the landing part was still a challenge. they would put their feet down 100 meters before their intended perch, and often overshoot it and have to fly around for a second attempt or find another spot.
they were begging for food from their parents – pa was about a mile away (out of ear shot, likely, from the incessant begging), and ma seemed un-phased by their constant calls, looking regal on her perch as she preened ignored their calls.
she did make one or two half-hearted attempts at a fish in front of us in our boat, but it was a leisurely sunday morning for all involved overall.
an amazing day out on the water with these majestic birds. special thanks to Mary, Roy, Carol, Megan and Cagney for this adventure!
A few days ago I spent a late afternoon in Briones East Bay Regional Park, a large expanse of mixed-use wooded/grazing land just over the hills from the East Bay. I knew it was going to be a good couple of hours when I spotted a hatch year (juvenile) bald eagle right after getting out of my jeep.
The eagle lazily circled and started to track south, and a few of the local resident red-tailed hawks went up to “usher it” onward and away from their territory.
My wandering quickly took me off the trail, onto a trail only known to my feet beneath me and the heart in my chest. My feet walked, climbed and scrambled up higher and higher onto a ridge line. I suppose I’m always looking for pumas and puma sign, and it seemed to be a likely starting point to find it. Once I was up on one of the highest peaks in the immediate area, there was a bit of a flat wooded area that I started to explore.
As I was quietly coming up a saddle from the main flat area down towards another little flat area, I saw a few young steer that started to move away from me – unused to seeing a person up there, I imagine. Also unused to seeing a person up there was the coyote that I just caught a glimpse of as it left its resting spot at the top of the saddle and slipped over the hill top out of sight, just 25 feet from me. I decided to have a little bit of fun with it, so I dropped down off the saddle towards a ravine that was thick with bay laurel trees and some oaks. I could hear the coyote moving there just out of sight below me as it trotted and paused in the crunchy dead leaf hubris of the forest floor, and for some reason I decided to give a short little bark. It was an earnest attempt to connect with this other being, not much thought went into it other than a deep desire to say hello.
What happened next was a 15 minute exchange of the two of us “talking” back and forth and checking each other out from a distance. At first I think the coyote wasn’t quite sure what I was (manimal?!!!). Below is a short recording of one of our exchanges. The coyote was probably within 25 yards of me the entire time, until some other hikers started to come up into the area after hearing the noise and the coyote departed. My voice is the short yip initiating the “conversation,” followed by the coyote and then us alternating.
It seemed as if it was alone, and I was very grateful to get to spend some time with it that evening. After scouting around I found an old deer kill, but otherwise I found no reason for the coyote to be so curious or possibly defensive. It’s probably too early for a den to be active with pups in January.
After watching the sunset perched underneath an oak that was sitting on high hill by itself, I followed a ridge line down into the valleys towards my vehicle. After hearing a pair of great-horned owls hooting right as the sun set, I was on the lookout – and they didn’t disappoint. As I approached the parking lot, one of them flew nearby and landed on an old fence post, surveying the encroaching dark for its breakfast.

Last week before I left Wyoming, I was fortunate enough to get out in the field with Brian Bedrosian, who is the Avian Program Director at Craighead-Beringia South. The task at hand was to catch a bald eagle, the last push to get the final of six transmitters attached to local bald eagles in the Upper Green River / New Fork River drainages, for a research project that is studying the effects of local energy extraction development on wildlife (aka gas wells aka fracking sights). For more on the details, see here.
We spent 10 hours on the New Fork River on Wednesday, rowing down the low and slow water with Chief, Brian’s dog, directing us.
To the East are the jagged peaks of the Windy Mountain Range, poking above the horizon eerily in the forest fire haze, and they look similar to the drastic edges and slopes found in the Teton Range. Meandering back and forth through the dry high-desert landscape is the New Fork River, a lush riparian zone that is home to many plants and animals, and a literal oasis.Everywhere else around us, as far as the eye can see, are sage-covered hills, slopes and small mesas – a sight which resembles a snapshot from the ocean, just beyond the breakers where the surface of the water is starting to peak and trough into rolling, moving hills of water.
And, also as far as the eye can see, are natural gas extraction pads. So it is that this area is the center of much debate and ecological concern.
We went through three separate bald eagle nesting areas during the float, using a trapping technique called a “float fish.” As we approached a nesting site, and there were eagles perched, we placed in the water upstream of us one or two of the float fish traps, then paddled quickly downstream ahead of them. These traps are essentially fresh-caught trout that have been modified with nooses of fishing wire and attached to a floating log with a few feet between the two. The concept is that when the eagle grabs the fish, the nooses secure around the eagle’s talons. The log is light enough that the bird can fly or swim safely to shore while we make our way back to grab it. Unfortunately the day yielded no results for our primary purpose (bald eagles trapped = 0), but it was a beautiful day to spend on a river. When your “work” entails floating and paddling down a river in August in Wyoming, life is good.
The next morning, we took a different tactic and instead of floating down the river, we selected two known bald eagle perch sites that were accessible by foot. We readied traps early in the morning – with Trapper Haynam joining us, also from Craighead-Beringia South – and before sunrise set them floating in the river below two separate eagle perch sites. After setting the traps we monitored them from not far away, above the river banks.
We then prepared for a long wait.
Suddenly, at 6:20 am, not 20 minutes after we had climbed back up the steep banks of the river to wait in the truck, an adult bald eagle soared over the fish and landed right by it! It seemed to toy with the fish and our emotions for a few moments, then after some careful scrutiny it took off. We hadn’t fooled it. Shortly thereafter a juvenile bald eagle came and circled above the fish a few times, then it was chased off by the resident adults who then perched upstream. It did not look promising.
Now the real waiting began. We had no eagle action after the initial excitement, but we did have several bull moose move through the area, including one who seemed to walk directly over the fish trap. I was worried that maybe we suddenly discovered a mutant carnivorous zombie moose and that we would have to free it from the fishing cord after it tried to eat our fish, but luckily it was the regular non-zombie, plant eating variety.
We decided that our setup was probably not going to attract any further attention from the eagle family, so we retrieved the trap and went to meet up with the rest of our crew at the other trap site that seemed to still hold some promise. The eagles hadn’t seen the fish yet but were in the area, and they had two of their young in the trees around them begging for food. My time there was limited as I had a long drive to do before the day was over, and just as I was about to leave for my drive back to California, we got one!
A hatch year bald eagle went for the fish, and although an adult was the preferred target, it could still be tagged for the study. Things happened VERY fast. We were posted up on a bluff above the river to monitor the trap, so when the bird hit it, we immediately drove down to the river bank, jumped out and ran to get close to it, before approaching the last bit of distance slowly and carefully. First priority was safety of the bird and us, and we didn’t want to create more stress than it was already experiencing. Brian handled it with amazing skill and professionalism. It had grabbed the fish, then when it realized it was caught, it flew/walked/swam over to a gravel bar in the shallow river where it was sitting when we got there.
To minimize stress (for the bird and us!), a falconers hood is placed over the head of the bird. This is also a common technique used in bird rescue and rehabilitation, and during exams of captive birds, because most birds tend to go into a hypnotized state of calm once the hood is over its eyes. The exam and attachment of the transmitter went quickly and smoothly.
After feeding the eagle some trout and giving it some water to be sure it was hydrated after its ordeal, we released the eagle back onto the river. After the hood was removed and it was placed on the ground, it took a few seconds for it to get its bearings, then it flapped its gigantic wings and turned east, getting over a fence and landing in a stand of trees upriver. Mission accomplished.
I must say that I had a lot of mixed feelings about capturing the bird, and about putting a transmitter on it, as the device is attached by strapping it around its body, and it sits on its back like a very small backpack. I find some solace in knowing that professionals like Brian are executing trapping like this in a professional manner and minimizing stress for the birds, and that these birds are participating in studies that could help the lives of many of their kind in the future. Your sacrifice does not go unnoticed.
The visual and auditory impact alone of the gas pads is tremendous on the landscape. The night that we slept there amid them all on BLM land near the river, the remote area looked like it was covered with lots of small towns due to the number of lights. It wasn’t until morning that I realized most of these “towns” were drilling pads, with a few ranches interspersed. During the night, loud explosions occurred with regularity. Many people in the area believe that these extraction processes could be poisoning their air and water. The ethics and methods surrounding energy extraction are hot topics right now, and the long-term impacts on humans and the greater ecosystem have yet to be determined – but I know that I am certainly concerned. Nothing comes without a cost. I urge everyone to educate themselves about this issue and the next time you fill up your gas tank or turn on your stove, take a second to think about where your energy is coming from. And be thankful for it.
Good luck my eagle friend, I look forward to thinking of you and your kind flying free over clean waters for many generations to come.
