Fall detection of cranes is also unreliable because hunters can be reluctant to report whooping crane sighting for fear that their hunting areas will be closed until the birds depart.

Why do whooping cranes die during migration?

Because most deaths of adult whooping cranes occur during migration, mortality may be linked to the quality or quantity of stopover habitats. A significant portion of the whooping crane population stops at the Platte River during migration ( Figure 5-6a,b ).

Do whooping cranes use the same habitats?

For example, Austin and Richert (2001) use sightings of unmarked whooping cranes to measure uses of migration habitats and conclude that high proportions of whooping crane sightings come from wetlands and agricultural fields. Whether the same birds use both habitats or some birds use only wetlands and some only agricultural fields is unknown.

What is canus the whooping crane?

What can we learn from whooping cranes?

And because they are so conspicuous, tracking Whooping Crane migrations can help other bird species by providing clues into how and why migration times are changing.
