Peregrine Falcons Nest on the Cliffs of Downtown Winnipeg
Following an alarming decline during the 1950s and 1960s, this spectacular falcon, also called the “Duck Hawk,” is on the increase again, now that DDT and other pesticides that caused thinning of eggshells have been banned. After an intensive program of rearing birds in captivity and releasing them in the wild (a process called “hacking”), this large falcon is reclaiming nesting grounds from which it disappeared a few decades ago. Although their habitat is mainly open country, especially along rivers and coasts and near lakes, a favorite nesting site nowadays is a tall building or bridge in a city. These urban Peregrines subsist mainly on pigeons.
Since 1989, pairs of reintroduced Peregrines have nested high atop the Radisson Hotel on Portage Avenue in downtown Winnipeg. Characteristically, Peregrines return regularly to favourite nesting sites. One pair after another has used the same spot in England since 1243. Since 2006, CBC Manitoba has provided a falcon cam in the nest of the downtown birds. Soon the feeding frenzy will begin. Click pic to start live falcon cam.
The Peregrine Falcon has been the favourite of falconers for over 3,000 years, ever since the nomads of central Asia first pursued game with trained hawks and falcons. Extremely acute eyesight, even in dim light, allows falcons to be very effective hunters around dawn and dusk.
Peregrines often migrate very rapidly between breeding and wintering areas, flying as much as 500 km per day. A female Peregrine that nested in Edmonton flew to Mazatlan, Mexico, in less than eight days and returned in six days.
With the exception of Antarctica, New Zealand, and Iceland, the Peregrine is found around the globe. Twenty-two subspecies are recognized throughout the world. Their great powers of flight have enabled them to establish nesting populations in the Arctic, and as far south as Tasmania, South Africa, and the Falkland Islands.
Peregrines breed from Alaska and the Canadian Arctic south locally through the mountainous West, and sparingly in East. Winters coastally, north to British Columbia and Massachusetts.

Peregrine Falcons Nesting in Brandon, Too!
When I posted the first story about the falcons in Winnipeg a few days ago, the Brandon cam wasn’t up and running. Today it is and what a great angle on the future festivities! The nest is situated high atop the McKenzie Seeds Building in downtown Brandon. There are two tabs along the top of the image, one for Winnipeg nest, one for Brandon nest. Click pic for both cams.
