Abstract
Unobstructed visibility is an important component of whooping crane (Grus americana) roosting habitat. Recent habitat modeling efforts suggest that unobstructed horizontal visibility is suitable at a minimum of 335 m. Unobstructed upstream and downstream visibility is also an important part of whooping crane roosting habitat, but quantification of that parameter has not been reported previously, or incorporated into species models. Data from the Platte River suggest that a minimum of 732 m of unobstructed upstream and downstream visibility is needed at whooping crane roost sites.
