We are sorry to report that one of the young Peregrine Falcons (female, green band) that fledged six weeks ago in downtown Boise was injured so badly on Thursday that she had to be euthanized. A maintenance worker discovered the injured bird on the roof of the Wells Fargo building, which is in the block next to One Capital Center where the nest box is located. Bill Heinrich of The Peregrine Fund retrieved her from the roof and saw that she had at least one broken leg. The young falcon was taken to a local veterinarian who discovered that both legs were broken. The radiograph shows just how extensive the injuries were. Evidently, she had collided with something, perhaps a powerline or a building. The experts determined that her injuries could not be repaired and she had no chance to survive on her own.

This loss is evidence that the first year in the life of a young bird of prey is extremely hazardous. In fact, more than half of fledglings do not survive their first year. Collisions, predators, weather and many other factors present tough challenges for young birds. We hope that the other three youngsters from this year’s breeding season will continue to do well.

8 July

After a few false starts, the young Peregrine Falcons in downtown Boise have fledged successfully. The falcon-watching team ended their official duties Thursday, although we know that they and many other people will continue to delight in watching the falcon family fly and call to one another for weeks to come. We are grateful to all those who volunteered to monitor the fledglings and keep them safe.

The young birds will continue to stay close to the adults for a while as they learn the finer points of flying and hunting. Family groups usually stay together for at least three weeks after the young fledge. By then, the young are capable of capturing prey on their own. By fall, they will begin to disperse, though it's impossible to say where they will go. The word peregrine is derived from the Latin word for "wanderer," an apt description of this species. Peregrine Falcons are found on every continent except Antarctica and live in a variety of habitats from tropics to deserts, from seashore to tundra, from sea level to 12,000 feet.

We thank all those who donated money, volunteered time, asked interesting questions, and sent notes of appreciation and encouragement during this year's falconcam season. We also thank our partners, Idaho Fish and Game Department and Fiberpipe, whose generous donations of time and resources make this project possible.


28 June

All the young falcons now have fledged, but not without a little help from their friends. Today, a female (with green band) landed on the ground near One Capital Center and was placed back on the roof. It's hot today (near 90) and she seemed more interested in staying in the shade than in taking another flight right away.

Several rescues have taken place since Friday when the youngsters first began fledging. Ground level is a dangerous place to be, whether in downtown Boise or in the wild. On the ground, they are an easy target for predators; downtown, the threat is from people and cars. Once these fledglings have more control over their wings, they will stick to higher perches.


24 June 4:30 p.m.

The falcon fledging season in downtown Boise is officially under way! Fish and Game biologist Bruce Haak reports that two of the young birds took the big leap today. One of them, a young male (with white band), fledged early this morning and spent some time sitting near the parking lot at One Capital Center, the building where the nest box is located. Because the fledgling was in an unsafe location on the ground, he was put back up on the roof, where he seems to be doing fine. The other one (not yet unidentified) spent much of the day safely on top of a building across the street from the nest. Observers reported lots of flying around and vocalizing by the adults this morning when the male was returned to the roof.


24 June

Peregrine Falcon chicks usually fledge about 42 days after hatching. That makes Sunday the official day but two of these young birds already know what it feels like to take to the air. After being bumped or blown off the ledge, two nestlings were rescued this week and returned to the top of the building (see previous updates).

Males usually fledge first because they are smaller, which allows them to develop faster than their bigger sisters. The nestlings have been preparing for their big moment by flapping, jumping, and taking short practice hops on the 14th-story ledge outside the nest box. In past years, they have flown and glided to the roofs of buildings across the street. If one should land in a precarious spot, such as the street, volunteers will be standing by, ready to call for a rescue. Fish and Game biologist Bruce Haak will return the young falcon to the top of the building where it can try again.


23 June

A second falcon was rescued today after apparently being blown off the 14th-floor ledge of One Capital Center in downtown Boise. Chris Lynch and other members of The Brothers Comatose band found the bird on the ground last night after a fierce storm with thunder, lightning, wind and rain blew through Boise. Fish and Game biologist Bruce Haak retrieved the nestling (female with blue band) from the Ruth Melichar Bird Center this morning and returned her to the roof of the building along with a pan of water and fresh food.

If anyone finds one of the young birds in need of assistance, call Fish and Game, 989-6815.

P.S. The webcam is working again. Fiberpipe located the source of the problem and sent a crew to the building this afternoon to fix it. There is not much to see, however, as the nestlings are now spending their days outside the box on the ledge.


22 June 4:00 p.m.

It has been an exciting day at the nest, especially for the young falcon that was found on the ground, 14 stories below the nest on One Capital Center. Barbara Newman discovered the nestling in front of the building on her way into work early this morning. Because the young ones are not yet quite ready to fly, the bird most likely used its wings to glide down but was nevertheless in a vulnerable situation. Fortunately, Boise television station KTVB and Cathie Havlina of Treasure Valley Raptor Rescue were notified and the story has a happy ending.

Cathie said the nestling appeared uninjured so she carried it up to the roof, one level above the nest. Fish and Game biologist Bruce Haak will go up there tomorrow with a water pan and a bit of supplemental food, although the parent birds will continue to feed their wayward offspring on the roof.

Though they are wild, these birds are fortunate to have many people watching over them, ready to help them out of a tough spot.


22 June 10:00 a.m.

We received reports earlier this morning that the Peregrine webcam is down. An inquiry was sent to the engineers that manage the camera, and we await an update on the camera's status.


15 June

From our mailbag:

Do the chicks need water?

In the nest, the chicks get moisture from the meat they are eating. Additional moisture and salt are exuded through the nostrils of the adults onto the food as they feed the chicks. After the young ones fledge and are more mobile, they will drink water when it's available.

Is the small chick being ostracized or ignored?

The smaller males generally don't need as much food as their bigger, stronger sisters, despite their persistent begging at mealtimes. The adults have a lot of time and energy invested in all these chicks and are focused solely on their survival. The biologists found them all in good health at banding.

Are the chicks in danger of falling off the ledge?

Most of us don't enjoy standing on the edge of a 14-story ledge and looking out into thin air but the chicks do it as part of the normal preparation for taking their first flight. It is highly unlikely that any would fall off but if one happened to leave the ledge prematurely, it could survive if it were able to glide to a safe landing.

Is there a camera outside the box?

We do not have an outside view of the ledge this year. We want to take this opportunity to again thank Fiberpipe for donating all the equipment and technical support for this project free of charge. After the chicks leave the box and fledge, we will try to post still images as they are available.


13 June

Like toddlers learning to walk, the chicks are exploring the bigger world outside the nest. Over the weekend, they began going out onto the ledge, where they are now likely to spend more and more of their time. Outside the nest box, they have plenty of room to vigorously flap their wings and take short hops to prepare for their first flight, which will occur in about two weeks. Now that they are acquainted with this new world outside, they have little incentive to return to the nest. If they do want inside, large rocks placed against the outside of the box provide the chicks with a step up, if needed, to get over the lip.

The ledge is wider than it looks on camera -- about 40 inches – and extends the entire length of the building. Several pillars along the span offer excellent places for the chicks to rest and find respite from the weather. The adults will continue to bring food to the chicks on the ledge. Whenever you hear the birds vocalizing, you can be sure one of the adults is delivering a meal.


8 June 1:05p.m.

We received these photos of the banding day from Thinh Do.

8 June

The chicks' adult plumage is beginning to show through their thick downy white coats. Each piece of down marks the spot where a flight or body feather will emerge. As the feathers grow in, the young birds preen, or groom themselves, to remove the tiny bits of down clinging to the tip of each emerging feather. This instinctive behavior continues throughout a bird's life to keep feathers aligned in tip-top shape for flying.

You may see the adult birds frequently reach toward the base of their tail during a grooming session. They are extracting a small amount of oil from their uropygial gland. Using their beaks, the birds coat their feathers with this protective, water-repelling oil. A good portion of the day in the life of a Peregrine Falcon – the fastest and one of the most impressive aerialists in the world – is spent on the all-important task of preening.


6 June 10:15

We are sorry that technical difficulties prevented us from restoring the camera view after the banding on Sunday morning. Fiberpipe is working on the problem currently and hopes to have the webcam back online soon.

The banding went off without a hitch and the chicks are now sporting new ID bands. There are two males (bands are black and white) and two females (green and blue). The banding team reports that all the chicks are in excellent health. It was interesting to watch the adults instantly come to the defense of the nest the moment that the team stepped onto the ledge. Suddenly the air was filled with the screeches of angry Peregrine Falcons, which flew from a tall building two blocks away to the nest in the blink of an eye. The birds were in attack mode for most of the half-hour that the team was with the chicks but quickly quieted down when they left.

6 June 09:20

The falconcam is has been down since yesterday. We just received a message from Fiberpipe that a network engineer is on his way to the One Capital Center building to repair it.


3 June

The banding team will head up to the nest at 9 a.m. Sunday morning to put an identification band on each chick. The band numbers will be submitted to a central registry so that if any of the birds are found or captured later, their numbers can be recorded and tracked. Scientists use this information to research such things as raptor survival, behavior, and migration patterns.

Because these are wild birds, no one has visited the nest box since the adult birds moved in. Banding is the only time that the team plans to venture out on the 14th-story ledge to fend off angry parent birds and handle the chicks. The team – Bruce Haak and Evin Oneale (Idaho Fish and Game Department), Jack Cafferty (The Peregrine Fund), and Ed Levine (Boise falconer) – has banded hundreds of birds through the years and will spend as little time as possible up there to reduce stress on the birds. The chicks also will be measured to determine gender.


1 June

Now more than two weeks old, the chicks are able to stand more erect. Their legs are not yet strong enough to hold them, but they can shuffle around the nest box on their haunches to explore their surroundings. In another week or so, they will be able to stand fully upright. This will be a relief to the adults because the chicks can then start feeding themselves, rather than relying on their parents to feed them every bite. At that point, both adults will shift into full-time hunting mode to provide enough food for their offspring, who are growing at lightning-fast speed.

The size difference between the chicks is likely due to gender. Males can be a third smaller than females, so they may never grow up to be as big or strong as their sisters. But they will be more agile in flight!


27 May 1:10 p.m.

The network engineers located a disconnected cable at One Capital Center and repaired the problem.


26 May 10:10 a.m.

The Peregrine Falcon webcam in Boise is down again. The network engineers that maintain the camera have informed us they are actively working to resolve the problem at this time. We will provide updates as they become available.


25 May

We apologize for the recent loss of the video stream. Technical difficulties kept the webcam down for several hours Tuesday and Wednesday but we are hopeful that the problem has now been fixed.

Many viewers have expressed concern about the health and safety of the chicks when they are left alone by the adults. Now that the young birds are older and have more feathers, they are better able to stay warm on their own. They also huddle together to generate heat. They are safe as well. Even when an adult bird is not visible on the camera, you can rest assured that one of the parents is nearby, ready to spring into action if necessary. Sometimes an adult is as close as the top of the box or outside on the ledge. Fortunately for the falcons, downtown Boise is mostly free of their worst enemies, such as Great Horned Owls and Golden Eagles.


24 May

Due to unknown technical problems, the Peregrine Falcon webcam has been down since yesterday. We apologize for the inconvenience. The problem will be resolved as soon as possible.


20 May

The rate at which these chicks will grow during the 45-day period from hatching to fledging never fails to impress. The chicks weighed only 1-1/2 ounces (40 grams) when they emerged from their shells, yet they will be full-grown when they leave the nest. By the end of June, these little fluff balls will be 18 inches tall and have a wingspan of more than 3 feet!

Because male falcons are smaller than females, the males will weigh about 21 ounces (600 grams) at fledging. The females will weigh about 35 ounces (1,000 grams). Males usually fledge several days sooner than females because their smaller size allows them to develop a bit faster.


18 May

Immediately prior to hatching, the yolk inside the egg, which nourished the embryo during incubation, was absorbed into the young birds' body cavity. The yolk continues to sustain a chick for several days, even without supplemental feeding by the parents. However, the chicks' begging instinct kicks in right away and the adults are feeding the chicks small amounts of food every day. The adults know just how much each chick needs to eat daily.

Back in the 1970s, The Peregrine Fund became highly effective at raising chicks in captivity, but knowing when and how much to feed chicks proved tricky at first because of the chicks' constant begging. Biologists soon learned exactly how much the chicks needed and, thus, avoided overfeeding them in response to cries that sound to human ears like, "more, more, more." The Peregrine Fund successfully raised and released more than 4,000 Peregrine Falcon chicks to the wild, but we know we can never do it as well as the chicks' natural parents.


17 May

The fourth chick hatched about 1:30 p.m. today.


16 May

Hatching began Sunday afternoon and three chicks were visible in the nest about 8:40 a.m. today. If all is well, the fourth chick will emerge within the next three days. The hatching took place during cold, windy, wet, even snowy spring weather, but the parents will keep them close for up to two weeks to ensure that the chicks stay warm until they are old enough to regulate their own body temperatures.


13 May

Now four weeks old, the eggs will soon be hatching! It is exhausting work but the tiny chicks have biological tools especially for this process. One of these is called an egg tooth, a sharp structure that grows at the tip of the beak. The chicks use this "tooth" to pierce the membrane inside and the shell. This allows oxygen to flow into the egg and fill their lungs. Previously, oxygen and carbon dioxide were exchanged via blood vessels in the membrane, but now the chicks will start depending on their lungs to breathe. This stage of hatching is called "pipping."

The chicks also develop a large muscle in the back of the neck, called a pipping muscle, which gives them the strength to chip their way out. Usually, hatching begins about 48 hours after pipping. The chicks will punch a dime-sized hole in the shell and then use their egg tooth to cut the shell in half, which takes about two hours. A few days after hatching, the egg tooth falls off and the pipping muscle disappears.

The adult birds know pipping is under way when they hear the chicks vocalizing from inside the eggs.


10 May 08:40

Fiberpipe notified us that the falconcam is currently offline. They are working to fix it.


10 May

After Peregrine Falcons were removed from the U.S. Endangered Species List in 1999, the states became responsible for them. The falcons are protected by state and federal laws, so Fish and Game biologist Bruce Haak continues to monitor them.

Many viewers have asked about what becomes of the chicks, past and present. That's hard to say because they are not outfitted with tracking devices, so we must wait until they are captured or recovered and their band numbers are reported. Here are a few tidbits on that topic from Bruce:

  • One bird that hatched in Boise went to southern California two winters in a row before dying at the Los Angeles airport.
  • Peregrines disperse long distances – up to 400 miles from their natal site – before establishing pairs and breeding.
  • Pairs may defend an area roughly 20 miles in circumference, so the youngsters will likely go other places to breed.

5 May

Now three weeks old, the embryos are developing quickly, assuming all is well in the eggs. If we could peek inside, the internal organs, a circulatory system and skeleton would be visible, as would a beating heart, feathers, and a beak.

Last year, all four chicks hatched, fledged, and survived at least the first few months of their lives. The adults were not as fortunate in 2009, when one of their four eggs did not hatch and one of the three chicks was killed by a power line shortly after leaving the nest. The mortality rate for young Peregrines in their first year is about 70%, according to Fish and Game biologist Bruce Haak. In general, however, a plentiful supply of birds to prey upon and a lack of predators make Boise a good place to raise a falcon family.


28 April

The eggs are now two weeks old. You may notice the adults standing up from time to time to rotate the eggs. This is an important activity, as it prevents the embryo from sticking to the inner membrane. If it is stuck, the chick may not be able to hatch properly and its survival will be jeopardized.

With a body temperature of 104 degrees, the adults are able to keep the eggs nice and warm even on cold spring days. During incubation, a special hot spot called a brood patch develops on the chests of the male and female. This bare patch of skin keeps the eggs in close contact with the parents' bodies for maximum heating action. The patch stays for up to two weeks after hatching because the new chicks are unable to regulate their own body temperatures for that long, depending on weather. The brood patch fades away as the young grow older and no longer need warmth from their parents.


26 April

A viewer asks: Does the female go into some kind of hibernation or sleep mode to be able to sit for all those hours without moving? To us humans, the idea of sitting still for so long seems intolerable, but this is normal behavior for birds of prey of both sexes. They do not waste energy. When we see these birds flying around, it's easy to think that's what they do all day, but they actually spend the vast majority of their time sitting still.

Birds of prey fly to hunt for food, attack or defend, court each other, and raise their young. Some are more active than others. California Condors, for example, must soar for hours over great distances to find enough to eat, yet even they conserve energy by using their enormous wingspan to float on air currents, thereby reducing the need to flap their wings. You may catch the Peregrines napping once in a while, but they are alert and busy with incubation.


21 April 2011

The eggs are now a week old and are quickly developing, assuming they are fertile. The eggs, which are slightly smaller than a chicken's, will be incubated by both adults until hatching begins in early May.

By the 1960s, Peregrine Falcons were gone from the eastern United States and large portions of the western states due to the effects of DDT. They were exposed to large doses of DDT after eating other birds that had come in contact with the chemical. This caused female falcons to lay thin-shelled eggs that broke in the nest before hatching. In 1972, the U.S. Environmental Protection Agency banned the use of DDT, which made recovery of the species possible. The Peregrine Fund pioneered many techniques for successfully producing the birds in captivity and releasing them into the wild. The organization released more than 4,000 young birds before the Peregrine Falcon was removed from the U.S. Endangered Species List in 1999, making it one of the most successfully recovered endangered species ever.


19 April 2:45 p.m.

Due to a computer problem at the One Capital Center building, the falconcam is currently offline. The connection may be restored later this evening.


19 April 2011

Many viewers have asked how to tell the difference between the male and the female. The easiest way is to observe the difference in their size – the female is larger and heavier. Admittedly, judging this pair's relative size is difficult when they aren't side by side but viewers should be able to discern the difference over time. Also, look for subtle differences in their markings. This female's color is duller and her head appears more solidly dark, while the male is brighter and has white on the sides of his head.

The size difference is called reverse sexual dimorphism and is common among falcons, hawks, eagles, and other birds of prey. "Reverse" refers to the fact that males are larger in most other species. Experts suspect that this adaptation evolved so that a pair can pursue a wider variety of food. The female's more powerful size enables her to capture and transport larger prey and the male's smaller size gives him greater agility. It may also have something to do with the female's ability to defend the nest and provide larger prey items for the chicks when they are older.


14 April 2011

4 peregrine falcon eggs

The fourth egg could be seen in the nest early this morning. Peregrine Falcons sometimes lay as many as five eggs, but four is typical.

The eggs will be incubated for about a month before hatching begins. The female will sit on the eggs at night but be assisted by the male during the day while she leaves to eat the food that he provides. Occasionally, neither parent may be on the eggs for short periods but this is not cause for concern. This pair has a lot of time and energy invested in these eggs and will do everything to nurture and protect them. Driven by hormones and instinct, these adults have little on their minds but the well-being of their offspring.


April 12

After the first egg arrived last week, many viewers were concerned about the eggs being left exposed in the nest for extended periods. This is normal and according to nature's design. Typically, Peregrine Falcons do not begin incubating until the third egg arrives so that all the eggs hatch about the same time. If incubation began with the first egg on the first day, one chick would hatch a week sooner than the last one. That would be a problem at feeding time because the taller chick would have a clear advantage.

Though our spring weather has been cool, the eggs are capable of withstanding temperatures below freezing. The chicks do not develop much inside the egg until incubation begins. Although the eggs appear to be alone at times, you can be sure that at least one parent is nearby, ready to fend off intruders outside of camera range.


11 April 2011

The third egg arrived early this afternoon. In past years, this nest has produced four eggs, so there may be another on the way by Wednesday.

Today's viewer question: Could she survive as a single mother? If the female were to lose her mate at this early stage, she would likely abandon the eggs because she would have to hunt for food to feed herself. That would interfere with successful incubation and leave the eggs exposed for long periods to predators and weather. If something happened after the eggs hatched, the male or female could, in theory, raise the chicks alone but it would be difficult. It has been done – some instances are documented – but it really takes two adult birds to feed hungry, demanding, and fast-growing chicks.


9 April 2011

peregrine falcon on nest

The second egg arrived today. We expect another one on Monday and possibly a fourth by Wednesday. Incubation then begins in earnest, with the female doing most of it and the male providing food for the two of them.

We have received a variety of questions in the last few days. We’ll start with a common one is: Where is the male? Often he is out of camera range, perhaps sitting on top of the box, out on the ledge or on a nearby building. He is busy keeping a protective eye on the nest and hunting for prey to keep the female nourished. Whenever you hear the birds vocalizing, or calling, they are communicating with each other.

Please check information under the “Facts” and “FAQs” tabs on this page for more details about the basic biology of this fascinating process. Coming Monday: Could she survive as a single mother?


7 April 2011

The first egg was visible this morning! A second one likely will come by Saturday. Typically, Peregrine Falcons lay 3-4 eggs.

Today's egg came earlier than last year, when the female laid the first of her four eggs on April 16. For pictures of the new egg, check out our Facebook page: http://www.facebook.com/pages/The-Peregrine-Fund/67192656239


1 April 2011

The audio stream for the camera was activated.


22 March 2011

The "falconcam" is now live.

Welcome to the 2011 season of the falconcam! A pair of wild Peregrine Falcons has been seen in and around the nest box on the 14th floor ledge of the One Capital Center in downtown Boise. They are likely the same adults as last year, as Peregrine Falcons were observed in Boise throughout this past fall and winter.

Currently the camera is broadcasting only the picture. We expect sound to be added in a few days.

Please note that your browser may require installation of plug-in software to display the video stream. Also, if you have visited the webcam page recently, your browser may show you an old copy of the page. If you do not see the live camera stream, refresh the page in your browser.


3 March 2011

Staff from The Peregrine Fund, Fiberpipe and the Idaho Department of Fish and Game prepared the Boise nest box for the season and installed the webcam. (video from installation is available here.)

Where are the nest and webcam located?

The camera is attached to a nest box on the 14th floor of the One Capital Center Building, 10th and Main streets, in downtown Boise. The box is on a ledge on the northwest corner of the building. The webcam may be viewed on a television monitor in the lobby.

What happened at this nest last year?

An adult pair produced four eggs. All of them hatched and all the young birds fledged. Here are some significant dates from the 2010 season:

  • April 16: First egg in the nest
  • April 23: Fourth egg in the nest
  • May 25: First three hatch
  • May 26: Fourth chick hatches
  • July 1: First chick fledges

Are these birds endangered?

The Peregrine Falcon was removed from the U.S. Endangered Species List in 1999. The Peregrine Fund was established in 1970 to recover the species by producing young birds in captivity and releasing them to the wild. The population of the species continues to be monitored by the U.S. Fish and Wildlife Service and individual states.

How did the falcons become endangered?

The population had been decimated by DDT, a pesticide that thinned the eggshells of many types of birds of prey, including the Bald Eagle. The use of DDT was banned in the United States in 1972.

How are they doing in Idaho?

In 2009, The Idaho Department of Fish and Game removed the Peregrine Falcon from the state endangered species list on the 10th anniversary of the federal delisting. Like all birds of prey, the Peregrine Falcon remains fully protected by state and federal law.

When did recovery begin in the state?

Peregrine Falcons were essentially gone from Idaho by 1974. Starting in 1982, captive-bred falcons were released to the wild in Idaho and nearby states. In 1985, the raptors were again documented as a breeding species and releases were discontinued. Eight falcons were released in downtown Boise in 1988 and 1989. Today, there are about two dozen breeding pairs scattered around the state.

Nest:

Falcons do not build nests. Eggs are laid and incubated in a “scrape,” which the falcons build by pushing the gravel out behind them with their legs.

Courtship:

The birds “bow” to each other by leaning forward with their heads low and their tails held high. They make an “ee-chupping” sound. Both the male and female bow and vocalize over the scrape and may touch bills. The male offers food to the female, which takes it from his talons or beak, often accompanied by ee-chups or loud vocalizations.

Pairs:

Peregrine Falcons generally keep the same mate from year to year, but if one dies, the surviving bird will seek another.

Eggs:

A typical clutch is three to four eggs, which are incubated for 32 to 35 days. The parents will use their beaks to roll and shift the eggs periodically during incubation. The male assists by sitting on the eggs while the female leaves to eat. The eggs will not hatch if they are infertile or the young dies during incubation.

Chicks:

Called an eyas, a chick stays warm under its parent during the brooding period. Chicks are fed by both parents, who make sure each chick receives enough to eat. They are in the nest for six to seven weeks.

Fledging:

Chicks prepare to leave the nest by flapping their wings in the nest, then taking short test flights. For about six weeks, they continue to be fed by their parents while honing their flying and hunting skills before striking out on their own.
