WPBO began annual monitoring of spring migrations beginning in 1979. By 1989 it expanded to include the monitoring of fall migrations and additional interpretative and research activities. In 1998, Michigan Audubon received a federal land patent

Staff and volunteers

WPBO has a paid staff during migration that includes a field naturalist, two owl banders, a waterbird counter, and gift shop employees. Its eighteen-member board and volunteers conduct most of the operational duties, including conducting birding field trips and the annual fund raiser called the "Spring Fling".

Raptor banders licensed by the U.S. Fish and Wildlife Service (USFWS) "lure the birds from the sky into nearly invisible nets. Each bird is immediately released after it is banded and the details are recorded on an official log sheet which includes the date, time, location, and the bird’s species, age and sex." Researchers report that the increased capture of Merlin falcons at Whitefish Point in 2004 was "an environmental indicator that the merlins had come back (after the ban on the pesticide DDT)."

 dispersal at Whitefish Point using nesting boxes and DNA analysis.

The 20-year owl banding project has recently increased the number of owls banded by as much as eightfold by the addition of audio lures that are used to broadcast owl calls. Owls are captured in 10 feet (3 m) high by 25 feet (7.6 m) wide specialty nets strung along clearings in the trees. Data are recorded with each banding and the owls are then released.

Researchers report that "nearly one-third of the Boreal Owls banded in North America have been banded by WPBO.... The recent success of all three owl research seasons has begun to document that, on annual basis, Whitefish Point may very well play host to the largest and most diverse owl migration in North America."

The waterbird count is conducted during both spring and fall migrations from the beach near the tip of Whitefish Point. The daily eight-hour count starts at sunrise with some the highest numbers occurring on inclement days, but Whitefish Point's frequent fog makes it difficult to count during this weather condition.
