A study using stable isotope analysis to determine the wintering locations and diets of individual Ipswich sparrows, and to relate those data to breeding success, was started in 2006. Feather samples were collected from over 100 adults, and the fates of their 70 nests were followed. In spring and summer 2007, the sample size was increased and data on the arrival and pairing dates of returning birds was collected.
