The fastest animal on the planet has returned to Wisconsin Public Service (WPS) and We Energies power plants. Peregrine falcons have been spotted at all four nest boxes — a sure sign of spring across the state.

Nest box cameras now live

Who’s who

There’s still a chance a new falcon could swoop into one of these nest boxes, but here are the peregrines currently in residence at each site.

  • Sheldon is joined by an unbanded female at the Weston Power Plant for the third year in a row.
  • Joel and Essity are nesting in Oak Creek for the second year in a row.
  • Hamm’s Solo is joined by an unbanded female in Port Washington for the second year in a row.
  • Barney and an unbanded female are nesting at Valley Power Plant for the second year in a row.

What’s next

The first eggs could be laid in the next couple of weeks. If all goes well, the first chicks should make their arrival later this spring. Look for updates on Facebook, Instagram and X all season long.

About the program

WPS and We Energies began installing peregrine falcon nest boxes at power plants in the early 1990s to support the species’ recovery in Wisconsin. Since then, 465 peregrine falcons have hatched at company facilities — representing 20% of all peregrine falcons born in the state. This program is just one way WPS and We Energies are building a bright, sustainable future.
