Identifying Raptors in Fall Migration in Wisconsin

Sat. Aug 14

10:00 am to 11:30 am morning session

11:30-12:30 lunch break

12:30 pm to 2:00 pm afternoon session

Instructor: William Mueller, Director Emeritus, Western Great Lakes Bird and Bat Observatory.

The Course:  The goal of this course is to learn to identify and monitor raptors during migration. We will especially focus on learning how to identify raptors in flight; that is how we are most likely to see them during their autumn migration.  Many field guides are useful for identifying a perched raptor, but the birds when seen in flight can look quite different from images in standard bird field guides, and their appearance can be confusing at first.

We will investigate:

  • Resources for learning and study (online sources)
  • Timing by species, and weather conditions
  • How to participate in a “hawk count” (an “official” count, or one you start by yourself)
  • Likely locations in eastern Wisconsin for autumn raptor migration (Geographic locations, and recommended sites)
  • Tools, field guides on raptors, and equipment
  • How raptors appear in various lighting conditions
  • How to identify and count the Wisconsin species.

Species that are possible in Wisconsin:

  • Vultures (2 species possible; 1 species likely)
  • Eagles (2 species)
  • Accipiters (3 species)
  • Buteos (6 species possible; 4 species likely)
  • Osprey (1 species)
  • Northern Harrier (1 species)
  • Falcons (5 species possible; 3 species likely)
  • Kites (3 species possible)
