In 2019, a report in Science made headlines worldwide, stating that North America’s bird population had decreased by 3 billion birds since the 1970s. Researchers deciphered this staggering number using advanced statistical methods integrating wide-ranging data sources, including multiple annual bird censuses, historical data and even weather radar data that can quantify migratory birds.
Now, researchers at the University of Florida want to take a similar approach with wild turkeys, painting a clearer picture of wild turkey abundance across the country. “Currently, there are few methods to reliably estimate wild turkey abundance, meaning that managers and practitioners often rely on indices, such as poults per hen and hunter harvest, to track trends in populations,” said Corey Callaghan, Ph.D., assistant professor of global ecology at the University of Florida. “Our approach will utilize these indices as well as multiple large-scale datasets to develop a method to estimate wild turkey abundance at multiple spatial scales, which will benefit state agencies in decision-making processes.”
