As the temperatures get colder and the days become shorter, Wisconsin skies will be filled with the bugling calls of Sandhill Cranes and Whooping Cranes on their migration south for the winter. Seeing a Whooping Crane or a Sandhill Crane in Wisconsin is incredibly exciting and a sign of conservation at work.
In the 1940s, Whooping Cranes were extirpated from Wisconsin and faced near extinction. Sandhill Cranes were scarce as only 25 breeding pairs remained in the state. This fall you can expect to see around 20,000 Sandhill Cranes and 80 endangered Whooping Cranes in Wisconsin.

The Sandhill Crane is a four-foot-tall slate gray to reddish brown long-legged wading bird with a red patch on its head. In preparation for migration, Sandhill Cranes gather in massive flocks on staging grounds to rest and eat. Within these flocks, you may catch a glimpse of a family of Whooping Cranes.
Whooping Cranes, standing at five feet tall, are white with black wingtips, a red patch on their head, and a black mustache-like mask on their cheeks. Unlike Sandhill Cranes, Whooping Cranes will not form large flocks with other Whooping Cranes, instead choosing to prepare for migration with their family of up to four, or joining a flock of Sandhill Cranes.

Migratory movement for cranes began in mid-October, will peak in November and likely conclude in mid-December. While cranes are on the move in Wisconsin, we ask that you keep your eyes on the skies and report your sightings of banded cranes to the International Crane Foundation. Reports of banded cranes provide scientists with valuable information about habitat use, migration patterns, flock formations and associations, survival of migrating cranes, and more!
When observing cranes, we first ask that you remember these crane-safe behaviors:
-- Stay 200 yards away from cranes
-- Observe their behaviors – head up and wings back means take a step back
-- Stay on the trails or remain in your vehicle when observing cranes
-- Respect private property
-- Report poaching or harassment to 1-800-TIP-WDNR
-- Look for bands on the crane’s legs and report your sightings to bandedcranes.org
In Wisconsin, many Whooping Cranes and Sandhill Cranes are banded with auxiliary markers, or colored bands, and aluminum bands that contain an 8-digit code from the USGS Bird Banding Lab. Whooping Cranes are banded on their right and left legs with a combination of red, white, green, or black bands unique to each bird.

Sandhill Crane band combinations vary based on where they were banded and who the banding coordinator is. For example, a Sandhill Crane banded in east-central Wisconsin will have a three-inch purple band with white letters on one leg and an aluminum band on the other leg. Contrastingly, a Sandhill Crane banded in south-central Wisconsin will have an aluminum band above a two-inch yellow band with black engraved letters on one leg, and on the opposite leg, they will have a combination of one-inch red, green, white, blue or yellow bands.
More information on Sandhill Crane banding protocols in the Eastern United States also is available at bandedcranes.org.
When reporting banded cranes, you will be asked to share the crane’s location and habitat, the time of your observation, the species and number of cranes observed, pictures taken to aid in identification, and the crane’s bands. It is important to note that even incomplete records of band combinations may be valuable as they can help scientists narrow down which cranes were sighted.
Finally, when reporting bands of cranes, please report one leg at a time and start by identifying the leg (right or left) and read off the bands from top to bottom. For example, the Whooping Crane pictured here would be reported as right: white red and left: white green red.
Reporting your sightings of banded birds is a great way to get involved in conservation in Wisconsin. The International Crane Foundation depends on sightings from citizen scientists like you to monitor Whooping Cranes and Sandhill Cranes and learn more about the health of these populations and the success of the Whooping Crane reintroduction.
