There
is obviously something about the Bank of the West building
that is very appealing from a falcon's point of view. Since
1990, a succession of peregrines have visited this location.
In recent years, the Bank of the West building has served
as the home-base for several territorial pairs. In 2001, history
was made when a successful nesting occurred at this site.
This was the first time in almost half a century that peregrine
falcons had nested in North Dakota.

In
May, 1990, two peregrines were observed near the top of what was
then the First Interstate Bank building. One bird was a mature female,
the other was a juvenile male. The female was unbanded. The young
male was banded, and had presumably been released into the wild
the previous year. Initially, these birds appeared to be a pair
looking for a nest site. Accordingly, a nest tray was hastily constructed
and installed near the top of the east wall. Even before this was
accomplished, however, the female had departed. The male stayed
longer, but after several weeks he also moved on.
In
hindsight, it is reasonably clear this first sighting was mostly
coincidental. The female was probably a "wild" bird on
her way to the arctic tundra, where one subspecies of the peregrine
falcon has traditionally nested. The young male bird was likely
also doing what comes naturally, wandering about looking for a mate
and a territory of his own.
Between
1991 and 1999, a single, mature peregrine was seen on what was then
the Community First National Bank building for several days each
May. Presumably this was the same - unbanded - female first sighted
in 1990, stopping for a rest on her long migration north. During
this same period, the building changed hands and new signs were
placed. Fortunately, Community First National Bank took steps to
keep the nest tray in place, waiting for use.
In
the spring of 2000, Fargo experienced what can only be characterized
as an invasion of peregrines. Moreover, these falcons were clearly
looking for a home of their own. At times, three or even four birds
were simultaneously attempting to lay claim to the nest tray on
the Community First National Bank building. It took a few weeks
for this process to work itself out, but in the end we had Fargo's
first true territorial pair of falcons. The male was a mature bird
named Dakota Ace. He was hatched in captivity in 1997, and released
as a fledgling in Sioux Falls, South Dakota. The female was a juvenile,
named Goldie, who had hatched the previous year in Omaha, Nebraska.
First
year peregrines rarely breed or nest. However, they can establish
territories and pair bonds that set the stage for subsequent nestings.
That is exactly what happened in 2001. Both Dakota Ace and Goldie
returned to the Community First National Bank building early that
year. By late April eggs were being incubated, and those eggs began
to hatch around the first of June. On June 22, the young were temporarily
removed from the nest tray for banding. At the same time, the tray
itself was replaced with a larger, covered structure.
The
young birds, two females and a male, left the nest box in mid-July.
Over the next month they became increasingly independent and self-sufficient,
ultimately striking out on their own.
2002
was a disappointing year for Fargo's falcons. Goldie who had nested
in 2001 failed to return. Presumably she did not survive the winter.
Surprisingly, Dakota Ace seemed to have no difficulty finding a
replacement. In succession, he paired with at least three different
females. The last to arrive was a bird named Frieda, who had hatched
a year earlier near Alma, Wisconsin. Frieda was first sighted at
the nest box on June 4, 2002. She and Dakota Ace were together through
the end of September, but no nesting occurred.
In
2003, Dakota Ace and Frieda returned to Fargo. By this point a different
nest structure had been installed, complete with a web camera in
one corner. Four young were raised, three males and one female.
At first, 2004 looked to be a repeat of 2003. Four eggs were laid
and the web camera continued to broadcast these events to a large
audience of viewers. Unfortunately, two of the eggs were blown out
of the nest tray by freak winds. It is suspected that the open design
of the structure contributed to this loss. The two remaining eggs
hatched and the young, both males, successfully fledged.
In
late 2004, the Community First system was acquired by Bank of the
West. From the outset, the new owners were committed to sharing
the falcons with the community by continuing to provide a home for
Fargos peregrine falcons. In addition, improvements were made,
both in the design of the nest structure and the quality of the
camera which records nesting activities.
