AMHERST, Mass. – The male peregrine falcon that nested with the same mate for 12 seasons atop the 27-story W.E.B. Du Bois Library at the University of Massachusetts Amherst, successfully raised 34 chicks during that time and thrilled thousands who watched online as he shared parental duties each spring has died at age 14.

The falcon, which was born in 2001 in New Hampshire, and his mate, a year younger, successfully nested at the library each year beginning in 2003. Since 2012 the pair had been a webcam favorite for thousands who have watched online as they hatched and raised their chicks each spring.

The male bird was found Jan. 15 injured on a snow bank on Sunset Avenue by a passer-by. He died early Wednesday while awaiting transport to a wildlife rehabilitation center.

Tom French, a state biologist who directs the MassWildlife Natural Heritage & Endangered Species Program, said the bird had a rich, full life. “Fourteen is particularly old for wild peregrines,” he said. “Ten is the typical old age for our birds.”

Following its discovery, the falcon was taken to Dr. Michael Katz of Hampshire Veterinary Hospital, who took X-rays and determined that it had no broken bones, although there were abrasions to its sternum and to one of its wings. It was suspected that the falcon hit a power line, perhaps while landing near a transformer, got his left wing tip tangled, and suffered an electrical shock that extended to his left leg and caused him to fall to the ground.

UMass Amherst research facilities project manager Richard Nathhorst, who has championed the peregrine nesting program at UMass, identified the bird as the library male.

French said the library nesting box will likely be home for a new peregrine family this spring, probably with the same female. “They mate for life, but they don’t mourn for a minute,” he said. “I expect that you have a replacement at the library already.”

The breeding season usually begins in March.

The UMass Amherst Libraries will turn the webcam back on in April, when “falcons will hopefully again make their home on the roof of the Du Bois Library,” said Carol Connare, libraries director of development and communication. The remotely controlled camera gives close-up views of both parents taking care of the eggs and chicks, as well as wider views of the youngsters exploring the roof as they grow and learn to fly.

In 2014, there were 269,279 page views of the webcam at http://www.library.umass.edu/falcons, an increase of 50 percent from the previous year. The site currently has a video compilation of highlights from 2014. The falcons also have their own Twitter feed: @DuBoisFalcons.
