Abstract
Whooping cranes (Grus americana), the largest North American bird species, have been listed as endangered for over 50 years. Though the population has grown significantly from near-extinction levels, these cranes remain vulnerable to habitat loss, particularly wetland degradation. Using ZCTA-level data, this study investigates how changes in United States wetland area affect whooping crane observations over time. We found that wetlands, specifically herbaceous wetlands, are associated with higher levels of whooping crane observations and should be targeted in habitat protection efforts. Our findings also help inform conservation efforts as the species continues to recover and recently reintroduced populations attempt to expand. Additionally, the use of ZCTAs to investigate the connection between wetland area and whooping crane sightings allows conservation groups to designate critical habitat areas more directly.
