Mayo Clinic Peregrine Falcon Program – Celebrating 31 Years
Since 1987, falcons have found a home on top of the tall buildings of Mayo Clinic in Rochester, Minnesota.
During nesting season (approximately mid-March to late June), this page features a live camera with 24/7, real-time views of where they live and raise their young. Throughout the year, this page features a film about peregrine falcons and their activities at Mayo Clinic.
March 13, 2018
Jackie Fallon from the Midwest Peregrine Society confirmed that both Hattie and Orton, last year's nesting pair, are in residence, but there is a second female on territory as well. Hattie was holding her off from the immediate Mayo Clinic campus but the other female (unbanded) is not giving up yet. We will share more information as soon as possible.
March 1, 2018: Four falcons have been observed here, fighting for occupancy in this territory. Three of the birds are banded but they have not perched long enough for anyone to read the bands.
Meet the Nesting Pair
Information to come!
In addition to this website, here’s how you can find out more about the falcons:
- Monitor and informational display in the subway (below-ground) level of the Mayo Building in Rochester, Minnesota, next to the patient cafeteria.
- Channel 199 and 706 (HD) on the Mayo Clinic Television Network for patients on our Rochester campus.
- Look up! In spring and summer, falcons are a frequent sight in the skies over Rochester.
As winter turns to spring, we will follow the falcons throughout their nesting season:
Early February: Settling In – One male and one female falcon take up residence in the nest (actually, a special box we built for them) on the roof of the 20-story Mayo Building. Between late March and mid-April, the female lays 2 to 4 eggs.
Early to mid-May: A New Generation – Eggs typically hatch 35 days after they are laid. They grow rapidly and fledge (make their first attempt at flight) at about 6 weeks of age.
Meet the Falcon – From 9 to 11 a.m. on the Mondays in the late spring/early summer, a naturalist from the Midwest Peregrine Society visits Mayo Clinic with an adult falcon.
Please note that this program is intended for Mayo Clinic patients while they are on campus to receive care and Mayo employees. Due to issues of privacy and security, we cannot accommodate tour groups and members of the public.
April 9, 16, 23 and 30
May 7, 14 and 21
June 4, 11, 18 and 25
May: Name those Chicks – After the eggs are hatched, it’s a Mayo Clinic tradition to name the baby chicks.
Late May/Early June: Banding Day – We announced the names and young falcons received their identification bands. Please note that this program is intended for Mayo Clinic patients while they are on campus to receive care and Mayo employees. Due to issues of privacy and security, we cannot accommodate tour groups and members of the public.
Summer-Fall: Follow the Falcon – The young falcons progressively develop under the watchful eyes of their parents, until they take flight to pursue independent lives. The parents, which mate for life, depart as well.
Year-Round: Check the online database of all banded Midwest peregrine falcons at http://midwestperegrine.umn.edu/?vw=search. Type “Mayo Clinic” in the search field to find falcons that were banded at Mayo.

July 25: We have received a report that all three chicks are alive and doing well. At one month since fledge, the chicks are starting to hunt for themselves and will soon be leaving the Mayo Clinic territory.
We have enjoyed watching Hattie and Orton all spring, and have been thrilled to see the progress of their three offspring, Generose, Epic and Lucky Lindy. Thanks to all our loyal falcon fans for following the Mayo Clinic Peregrine Falcon Program during its 30th anniversary year.
Enjoy these photos of the chicks when they were banded and named on June 1, 2017:
Generose (female, left) isnamed for Sister Generose Gervais,the fifth and final Sister administrator of Saint Marys Hospital.
Epic (female, at right) - named for the Plummer Project - Epic Implementation, the largest practice initiative ever undertaken by Mayo Clinic.
Lucky Lindy (male, shown below left) - the nickname of Charles Lindbergh, Minnesota native who collaborated with Mayo's aero-medical unit in World War II, which developed the G-suit, high-altitude oxygen mask and other innovations. 2017 marks the 90th anniversary of Lindbergh's trans-Atlantic flight.
June 26: All three chicks have fledged! We have occasionally seen one or two of the fledglings return to the nest box which has been their home, but they are spending more and more time away from it now. They are most likely nearby, although out of view of the falcon cam. (The white spots you see on the image are specks of moisture on the camera lens.) This is the time when the fledglings -- Generose, Epic and Lucky Lindy -- are fine-tuning their flight skills. They also chase their parents for food and even make attempts at catching their own.
June 22: Epic, one of the females, fledged and has been spending time outside the nest box, along with Generose. You may occasionally see one of the fledglings on the roof of the nest box as they are becoming more comfortable leaving the box that has been their home. Lucky Lindy, the male, is the youngest of this brood and has not yet fledged.
June 19: One of the three falcon chicks fledged this morning. Generose, one of the two females, made her first attempt at flight and was on the roof near the nest box. We can expect Epic and Lucky Lindy to fledge within the next week. Hattie and Orton will continue to provide food for the chicks for the next month or so and continue to stand guard, chasing away threats to the chicks. In the photo below, taken at 9:45 a.m. on June 19, Epic is perched on the edge of the nest box while Lucky Lindy is inside the box. You will still hear them begging for food whenever their parents are near -- it seems like they can never get enough!
June 13: The three falcon chicks are growing like weeds and will be taking their first flights within the next week. It's always amazing how quickly they grow in such a short period of time. With these growth spurts the chicks also spend a lot of time sleeping, especially when the weather is warm and humid. Once the chicks are about 4 weeks old, the adults spend less and less time in the box. At this age, the chicks can feed themselves (although the adults bring the food) and feeding time becomes a feeding frenzy! Don't worry -- the adults are still standing guard and are actively chasing away any threats to the chicks. The chicks are eating LOTS of food, so both adults are now out hunting for the three hungry mouths, plus hunting enough food for themselves, too. This is why you may often hear the chicks begging for food -- it seems like they can never get enough!
June 1: The three chicks were given identification bands and names today. We are pleased to announce their names: Generose (female) - named in honor of Sister Generose Gervais; Epic (female) - named for the Mayo Clinic Plummer Project - Epic Implementation; and Lucky Lindy (male) - honoring Charles Lindbergh, famous aviator from Minnesota, and the 90th anniversary of his historic trans-Atlantic flight.
May 13: All three eggs have hatched, and Hattie and Orton are now busy caring for their chicks, feeding them and keeping them warm. If all goes well, we will band and name the chicks during a special event on Thursday, June 1. In the meantime, enjoy watching the activities of this new family of falcons.
May 10 - Mayo welcomed its first chick of the 2017 nesting season. The other two eggs will, hopefully, hatch over the next day or two. If all goes well, we plan to band and name the chicks in about three weeks. Stay tuned for details on the date and time, but for now, enjoy watching Hattie and Orton care for their chick.
April 5 - May 10 - Hattie and Orton are actively incubating their three eggs. The female does most of the incubation of the eggs, only getting off them briefly for a few hours each day. During that time, Orton takes over the duties to keep the eggs at a constant temperature. While Hattie is busy keeping the eggs warm, Orton does all of the hunting for himself and the female. Three to four eggs are the typical number laid in the clutch. With Hattie and Orton, true incubation began when egg #2 was laid on April 2. We can expect hatch to occur approximately 33 to 35 days later, so keep an eye on the falcon cam around May 5. It can take up to 24 to 36 hours for a chick to full hatch once it has "pipped" through its shell.
April 2 - Hattie laid a second egg this evening. She now seems to be staying closer to the nest box.
March 31 - Hattie laid her first egg at 12:54 p.m. We will be monitoring to see if more eggs are on the way!
March 27 - A puncture wound below Hattie’s right eye appears to be healing. There is no sign of the other female on territory.
March 24 - Observed an injury on Hattie’s right eye. We will monitor it for infection.
March 13 - A territorial battle was observed: Hattie and an unbanded adult female are vying for this nest box.
- The peregrine falcon is a raptor – a bird of prey that hunts and feeds on other animals, typically birds.
- The peregrine falcon is a crow-sized bird (1-2.5 lbs.) with long, pointed wings. Young birds, which are brown and cream colored, are heavily marked with streaks. Adults have a blue-gray back with a light, striped underside and a dark-colored head.
- Its Latin name, Falco peregrinus, means “wanderer.”
- The male is about one-third to one-half smaller than the female.
- The birds typically mature at two years and can live to nearly 20 years old.
- Peregrine falcons can migrate more than 15,000 miles per year.
- The peregrine falcon is the fastest member of the animal kingdom, able to reach speeds over 200 mph in spectacular dives called a “stoop.” It lives on every continent except Antarctica.
- The falcon has long been associated with European and Middle Eastern royalty. Records of the sport of falconry (using a trained raptor to hunt wild game) date back more than 4,000 years.
- Historically, the peregrine falcon preferred to nest on high cliffs near water. Today, the bird is also found on towers, bridges, and tall buildings such as those found on the Mayo Clinic campus in downtown Rochester.
Mayo Clinic and the Stewardship of Nature
The Mayo brothers, Dr. Will and Dr. Charlie, often said they grew up in medicine “the way farm boys are taught to farm.” All their lives, they shared a deep appreciation of nature. Dr. Will was an early advocate of efforts to clean the Mississippi River. Dr. Charlie made Mayowood, his country home, a preserve for many species of wildlife. The Sisters of St. Francis, who founded Saint Marys Hospital and are active in many activities at Mayo Clinic and beyond, uphold a reverence for nature.
When DDT was banned in 1973, recovery efforts began for many threatened species, including the peregrine falcon. In a program that has grown steadily over the years, captive-bred chicks are released, monitored and tracked as they learn to fly and become independent.
At the invitation of the not-for-profit Midwest Peregrine Society, Mayo Clinic began hosting the falcons in 1987. Mayo’s Peregrine Falcon Program is a popular annual activity, involving the support and collaboration of many colleagues. Some patients tell us they schedule their medical appointments in order to be on campus when the falcons are in residence!
Name the Falcon and Banding Day
Banding Day is a very special event in the lives of the young chicks. Naturalists working with the Mayo Clinic team carefully remove the falcon chicks from the nest box on top of the Mayo Building and bring them to Geffen Auditorium. There, they are given a quick physical assessment and a metal identification band is placed around each fledgling's leg. Each band is uniquely lettered and numbered so that if the falcons are observed later, they can easily be identified. Before returning the bird to the nest box, their official names are announced.
Details about the 2018 event will be shared when available.
Where are they now?
You might be wondering what has happened to some of the falcons that fledged from Mayo Clinic.
- February 20, 2018: We have learned that Generose, a 2017 fledge, was found deceased in Marshalltown, Iowa, in October 2017. We also learned that Triumph, a 2013 Mayo fledge, has been seen in downtown San Antonio, Texas. Triumph, a male, has nested at Multifoods Tower in Minneapolis the past few years.
