History of the Du Bois Library Falcons

Falcon Cam 2017: Four eggs were laid in April (we are not sure of date; due to the weather, the cam went live a bit later than usual.) Over the weekend of May 6-7, two eggs were lost. One disappeared overnight and the other was eaten by the female parent. On Wednesday, May 10, 2017, two chicks pipped and then hatched. 

In May 2016, the 14th generation of Peregrine Falcon eggs was laid; the second brood for the three-year-old falcon pair that took over the nest box following the departure (after the 2014 season) of the previous falcons that lived in the nest box for twelve consecutive years, the quick arrival of this new couple is a soaring testimony to how far the species has come since near extinction in the 1960s.

The Pioneer Valley has been active in falcon restoration efforts since the adverse effect of DDT, an agricultural pesticide, became public knowledge in the sixties; one of the first release sites was on Mt. Tom in Holyoke between 1976 and 1979, according to the Massachusetts Division of Wildlife and Fisheries. The Peregrine Falcon chicks were bred, raised and released by the Peregrine Fund, a non-profit organization created in 1970 dedicated to saving birds of prey from extinction. Peregrine Falcons are one of the most widely distributed birds, living in every continent except Antarctica, but DDT in the United States decimated their numbers, leaving no nesting pairs east of the Mississippi River and creating a desperate need for restoration organizations.

With the strong conservation efforts in the Pioneer Valley, it’s no wonder that by 1988 UMass Amherst had begun its own falcon program, setting up a nesting box on the 13th floor of the Lincoln Campus Center. Inside were five chicks, flown in from Peregrine Fund headquarters in Boise, Idaho, to be raised and released that summer. Kate Doyle ’90, G’97 and Katherine Kripp ’90, G’97, then graduate students in Biology at UMass Amherst, were given the task of feeding and monitoring the chicks until they fledged. The women, wanting to avoid human contact with the birds, watched and recorded their activity through a spotting scope from a rise near the Campus Pond and secretly dropped food into their nesting box.

“The job was partly about outreach,” says Doyle. “People would see us with this huge scope in the heat of summer and ask us why we were out there. It allowed us to explain the project and teach them a little bit about Peregrines and their endangered status.”

That July the five falcon chicks took flight, eventually leaving the Campus Center never to return, and marking an 11-year falcon chick hiatus for UMass Amherst. In March of 1998, a nesting box was installed on top of the W.E.B. Du Bois Library with an adult falcon observed going in and out of the box that same year. The next May a nesting pair was seen flying frequently to the nest box with prey, signaling the potential return of falcons to campus.

And return they did, with a total of forty falcon chicks fledged from 2003-2016!

A live web camera was installed atop the Du Bois Library in 2012, allowing the public to watch the pair raise their chicks, and garnering more than 200,000 viewers in 2014 – double the audience in 2012. The webcam is made possible by the UMass Amherst Facilities Planning Division, UMass Amherst Information Technology (IT), the Libraries' Systems and Web Management Department, the Massachusetts Division of Fisheries and Wildlife (MassWildlife), and the Friends of the Libraries, all of whom have helped in supporting, installing and maintaining the camera.Viewers can stream the webcam from the Library website at and it is compatible with Android, Blackberry, and iPhone/iPad/iTouch devices, allowing everyone to watch the falcons as they grow and fledge. The website also provides links to the Du Bois Falcon twitter page, @DuBoisFalcons; and the Facebook page,; and additional falcon information from MassWildlife

Donations from viewers allowed for a new, updated camera to be purchased in 2013 and provided the funds to fix the camera a year later, when it suffered a suspected lightening strike in June.  With viewers’ support, the falcon program will continue to run for as long as the falcons make the Du Bois Library their home.

Every season, a legion of eager viewers tune in to the Falcon Cam and 2016 was certainly no exception as the falcons’ social media presence soared! Thanks to a group of behind the scenes volunteers, and a supportive online community, @DuBoisFalcons and the Libraries’ Facebook Page were vibrant forums where Falcon Cam viewers interacted, gained knowledge, posted screenshots and videos, and engaged with each other through a shared love of all things Peregrine.  

We welcomed hundreds of new followers on Twitter and Facebook and gifts from generous donors raised a total of $2,425 for Falcon Cam maintenance and upgrades. Thank you to all who donated!




The official timeline of the UMass Amherst Falcon Program was created by Tom French, at the Massachusetts Division of Fisheries and Wildlife, who has assisted the UMass Amherst falcons since 1988.

Library Tower, Amherst (Du Bois Library) - Nest box installed March 27, 1998 on the 26th floor lower roof parapet wall of 28 story building. Previously, in 1988, five chicks were hatched on the 13th floor of the nearby Lincoln Campus Center.

2002 – A pair present but abandoned the nest box early. They were frequently harassed by a territorial Red-tailed Hawk.  Peregrines seen on January 25, 2002, and October 21, 2002, but it is unknown if they were the same pair.

2003 – One unbanded female fledged on July 15 and one unhatched egg was collected.

2004 – On June 5, two females and two males were banded.

2005 – On May 31, two females and one male were banded.

2006 – On June 5, one female and one male were banded. On June 20, the male was picked up on the ground and returned to the roof. The female fledged.

2009 – On May 27, three females and one male were banded. A new nest box with a camera was installed in October.  One of the females was found nesting on a smokestack at a power plant in Martin’s Creek, Pennsylvania in 2012, raising four chicks.

2010 – On May 28, two females and one male were banded. The un-hatched egg seen on May 20 disappeared over the previous week.  One of the females was picked up on July 28 on the ground near the Library with a broken corticoid and taken to Tufts. She was released in Grafton around October 2, 2010.  The male was picked up injured in Virginia and was in rehab; his outcome is unknown.

2011 – On June 8, two females and two males were found in the box. Three flew away and one female hid in the box and was caught and banded by Ralph Taylor and Dave Fuller. Over the next several days, each bird ended up on the ground and was banded. A wing of the first Upland Sandpiper documented as prey by MA Peregrines was recovered on June 8, along with the wing of a Least Sandpiper. One of the males was found dead on September 8, 2011, in Cohasset.

A female chick hatched on June 2, and the male chick hatched on June 4. On June 9 and 10, both chicks were treated for a mite infestation, after MassWildlife and UMass Veterinarian Dr. Paul Spurlock called for intervention. (The mite was later identified as the Carnid Fly, Carnus hemapterus.) On June 29, officials from Mass Division of Fisheries and Wildlife banded both chicks. The female chick is Black 76/Green BS and the male chick is Black 01/Green BE. 

2016 - Current Female #1 - Banded in 2013 in Sorel, Quebec; three years old. Current Male #1 - Unbanded: estimated to be about three years old.
