A professor from the University of Wisconsin-Stevens Point traveled with one of his former students to Greenland over the summer to study peregrine falcons and document changes in their lives caused by climate change.
Biology professor Bob Rosenfield traveled with alumna Maddie Hardin to Greenland for two weeks to document the ages of nestling peregrines, based on the development of their feathers, and compared the data to information collected in previous years. Rosenfield said he believes the research will show that peregrines are responding to warmer temperatures by changing their life events such as laying eggs earlier in the year, leading to chicks being older at a given time of year than in the past.
