Nine of 18 first nesting attempts successfully fledged offspring.

Of these, seven pairs attempted second broods, three of which also successfully fledged.

Of the eight additional second attempts (replacement clutches), three fledged successfully.

In 2011, 8 breeding pairs nested, successfully fledging 14 young.

Fifty to seventy percent of the nests successfully fledge young.

Usually only one chick survives to adulthood, though in some cases as many as three will successfully fledge.

Larger nests are associated with greater numbers of young successfully fledged, and appear to be sought after.

Over the five years of the project 152 chicks fledged successfully.

Nesting success is low, with only 23% of nests successfully fledging a chick.

By 2012, three nesting pairs were confirmed at Whitefish Point that successfully fledged eleven young.
