The Swans Of Eagle Story
Mute Swans are not indigenous to Idaho, but there is a healthy population of them in the greater Boise area. Many, if not most, of these beautiful birds are the offspring and progeny of a mating pair that have used a nesting area in Eagle, Idaho since 2004.
When the pair first arrived in Idaho, they nested at the bottom of a working gravel pit on Eagle Island. Ron Sali, the owner of the pit, adopted the pair and went so far as to take nesting material down into the pit to help the swans build their first home in the hole. In 2006 the pits were allowed to fill with water and the gravel mining ceased. The swans were displaced, but apparently they appreciated Ron's hospitality as they found a new nest site next to a stream on the property. My introduction to the Swans of Eagle came in the spring of 2011. Ron had turned the old gravel pits on Eagle Island into a wildlife rich habitat with two deep water lakes, and built his ranch home there. I had only been able to observe wildlife on and around the lakes from the outside, as the ranch was fenced and posted. Driving by the property one day I noticed the gate was open, so I boldly ventured up the long driveway to ask permission to shoot photos inside the perimeter. Ron answered the door, checked my ID, looked at some samples of my work and then, against his better judgement, gave me limited access if I promised to get some shots of the swan family for him. Ron told me that the swans had produced approximately 70 offspring on the property so far, and he considered them members of the family. I had never even seen the swans from outside the fence and knew nothing about them, but I was intrigued by the challenge and accepted the opportunity.
My few prior contacts with wild swans had been short and from a distance. Translated, that means I knew almost nothing about them. But, I wanted, and needed, to get some quality images to complete my part of the bargain, so I went to the nesting area. It wasn't long before these impressive and imposing birds captured my imagination and attention. I did a little Google surfing to understand a few of the birds actions, but most of what follows is based on my observations and should not be considered scientific swan facts.
My first visit to the nesting area was on May 10th. Ron had warned me that the male was very protective and could inflict pain if provoked. Over time I learned to recognize the various poses he would adopt as a warning. I set my tripod up at a respectful distance and watched for several hours.
The male clearly defined the edge of his territory and got aggressive if I got closer. I clearly did not want to make any enemies this early in our relationship.
I didn't know Ron had named the adult swans Papa and Mama when I first visited the nesting site. I gave Papa the nickname of "Sumo Duck" because of his size, and the posture he adopted when swimming by on patrol, as well as the odd plodding walk he adopted on land when he was trying to intimidate me into moving away. I usually moved!
If I did get too close, Sumo would charge straight at me, creating a great fuss in the water. He always stopped just short of making physical contact .... except once!
I had gotten very low in the grass at the edge of the nesting pond to get a water level shot. He assumed a warning pose and it looked like he was going to swim by me. But he didn't. Swans use the bony "elbows" in their wings as a weapon and Sumo hit me in the face full force with one huge wing. Fortunately I was looking at him through my viewfinder and the camera took the brunt of the hit, but he drew blood.
Imagine my surprise!! In nature,size matters. Bigger is almost always better. I had gotten down to ground level, looked small, and was an easy target. From that moment on, I never got into a position around Sumo where I was shorter than him, or otherwise vulnerable.
So, I selected a position on a small hill near the nest that allowed me to look down into the nest, and was just outside Sumo's safety border. The female would rise off the nest every 20 to 30 minutes to shift the position of the eggs beneath her, so I was eventually able to get a count. There were 8 eggs and they were HUGE! In my ignorance I wondered how she could fly with all those eggs inside her body. She can't, and she doesn't. Dumb me. I did not know that the eggs aren't all in there at one time. Swans lay eggs at a rate of about one a day and can spend as long as two weeks filling the nest. Incubation starts for all the eggs at the same time, once the last egg has been laid.
I wanted to be there when the cygnets were hatching, so Ron and I would look in on the nest regularly to watch for any signs of activity. Even though the eggs are laid over a period of time, they all (usually) hatch during a 24 hour window. I was impressed that over the two weeks that I waited and watched for activity, I never saw the female leave the nest.
On May 23rd I got a message from Ron that there appeared to be activity at the nest. By the time I arrived, all the eggs had hatched, but the shells were still in the nest, indicating that the cygnets were still only a few hours old. There were eight cygnets and all appeared healthy. But, to my surprise, they were not white. Five were predominantly gray and the other three were shades of tan.
It seemed a very short time from being born until the cygnets were given their first swimming lesson. Mama ad Papa marched them down to the waters edge on the very first day of their lives and calmly waited for them to jump in. It took only a few moments before the first brave soul took the plunge and then the next six quickly followed. But not number eight. This young swan was not sure that water was his friend and took several extra minutes of coaching before he stuck a webbed foot into the pond.
Once the cygnets got wet, the lessons came quickly. There was a tour of the nest-side pond, with a few stops for snacks.
What surprised me most was that the adults then took the new-born cygnets on a trip downstream from the pond and then back up-stream. There is a small rock dam in the stream that created the pond behind it. The water behind the dam is calm but the water going over the rocks and into the stream is quite fast. So, the trip downstream was easy .....
....but the the swim back to the pond and the nest was a challenge. Mama and Papa cut the kids no slack at all. The adults swam upstream through the little rapids and over the rocks to the pond and waited to see which of the newborn would make it all the way.
The little guys had to paddle their tail feathers off to make any headway against the strong current and repeatedly got pushed back. I stood on the shore encouraging them to go to the side but doubted that any of these day-old cygnets would succeed. It took a while, but not one of them quit until they got to the pond. All this on their first day out of the egg! I felt like a wimp. Thinking about this behavior made me believe that this trip downstream and back was a test. I believe that any cygnet that couldn't make it back to the pond would have been abandoned.
One week later, June 1st, I got back to check the family progress. The cygnets seemed like they had doubled in size and quadrupled in confidence. They accompanied the adults out on the big lakes to feed and showed no fear of venturing away from Mama and Papa to forage on their own. The cygnets were still little fluff balls, but they had already adopted an air of dignity and grace. This was all bad news for me. During the nesting period I had been able to get close to observe and photograph. Now the family was free of the nest and could travel anywhere on the ranch, even upstream to the neighboring properties. I would need to wait for the family to forage along one of the edges of the lakeshore in order to get close enough to get good photos.
After only two more weeks (June 15th) the cygnets had made another large jump in size and appeared a bit awkward. They had entered a pre-adolescent "ugly duckling" stage. Like human teenagers, the focus was on feeding the incredible growth required to get them ready to fly south for the winter.
Although they spent almost every waking hour feeding, it appeared that the family needed to spend a certain amount of time on shore to let the cygnets dry out and get warm. The young swans were still fluff balls and didn't yet have the full set of waterproof feathers.
Sadly, one of the gray cygnets was missing from the family. I found the body floating in the pond near the nest, but there was no sign of what might have killed it.
When I returned on June 24th the cygnet count was still at seven. On this visit I could not see any obvious changes to the size or coloration of the cygnets.
It was August 5th before I got back to the lakes. The transformation was significant. Feathers were replacing the fluff and the cygnets were nearly half the size of the adults.
I know swans are powerful swimmers but I was still impressed by the size and development of the feet and legs. Mute Swans have huge feet!
The end of summer was rapidly approaching and I had not seen any of the young swans trying to fly. In fact, their wings still looked totally undeveloped. I was also surprised that the feathers weren't white. I expected the colored cygnet fluff to be replaced by adult coloration. It was also notable that the tan/white cygnets bills were developing an orange coloration but the gray/white bird's bills remained dark gray. During my absence we had lost another gray cygnet.
On August 24th (and subsequent visits) I found the lakes populated with 7 to 15 other swans. Most looked like yearlings because they were not yet the size of the mature resident adults and their bills still had not fully turned bright orange. It was only a guess, but I imagined these visitors were prior years cygnets.
Every time I visited the lakes I had hoped to see the swans airborn, but it very rarely happened.
The young visiting swans did reward me with one late evening fly-by.
Typically the swans would fly south for the winter but Ron reported the big birds were still in town and stopping by regularly to feed. Maybe it was because Boise was having a very mild winter, or possibly because the 2011 cygnets developed late and were not yet up to the trip. Remember, these are not swan facts, simply observations.
When I visited on 11-10, 12-21 and 1-7-2012 there were swans. The bulk of the 2011 family was still travelling as a group but I never saw more than 5 of the cygnets at one time. There were also regular visits to Ron's Three Rivers Ranch by prior years offspring (?) or other swan relatives. The young birds were easy to spot because they still had not shed all of their colored feathers. Because they were somewhat independent and now flew to other locations, it was possible that one had found a boyfriend and eloped. I never got to see the 2011 crop of cygnets fly so I have no idea what their underwing coloring would look like.
The new 2012 nesting season started for me on 3-23. I found the two adults swimming and feeding together and none of the kids were anywhere to be seen. Swans regularly chase the cygnets out of the nesting area as soon as they are able to fly and forage for themselves. It was mating season and I guess that Mama and Papa didn't want kids around to spoil the mood.
On subsequent visits (4-1 and 4-29) it became obvious that the happy couple was going to use the nest from the prior year. By the 29th there were six eggs in the nest and Papa had adopted his hyper-defensive "Sumo Duck" attitude.
I don't know how they do it, but these swans have a way of pushing their chests down into the water and forcing a wave to form in front of them. It seems to happen when they are sending a warning message. Whenever I saw Sumo assume this posture I chose to back off, never wanting to find out what the next level of swan self-defense is.
It was strictly coincidence that my next visit was 5-10-2012, exactly one year after my first visit to the nesting area. Deja Vu! The only difference was two less eggs. But now the hatch-watch has started for this years crop. Updates to follow!!
And that was the last line that was written in the original story.
There were dozens of visits and photos made during subsequent years, but no news was shared on this site.
I say I was busy, you can say I was lazy.
Now, in 2025, we have this update.
I continued to document the swan family drama for several more years. Dates shifted slightly, the number of cygnets that were hatched, and the number that made it to adulthood varied year to year, but the process of becoming, and being swans was locked into swan DNA. During this entire period the swan nest was ruled by Papa/Sumo Duck, the family patriarch. Papa would occasionally, and for unknown reasons, return with a new female partner. But the process never changed. Then, in November of 2024, Ron was watching the family on the shore of the lake and observed what he considered unusual behavior. In response to some swan family signal, the female took all the cygnets a distance down the shore away from Papa. Ron could only watch, helplessly, as Papa wobbled briefly, then laid down and died.
20 YEARS OF COURAGEOUS COMMITMENT
In 2025 a new swan family was started at the ranch in Eagle, Idaho. At the time of this writing neither Ron, or his staff, had located the new swan family's nesting site. But, the beat goes on. The new swans will be family, just like all the Eagle, Idaho swans that preceded them. If you would like to see a few more photos taken over the years, check out this gallery of The Swans of Eagle
