For his graduate degrees, Kyle spent a decade studying cliff-nesting thick-billed murres in northern Hudson Bay as part of a long-term monitoring program. Diet and the growth rates of chicks (as held by Kyle in this photo) are monitored annually. Since the 1980s, murres have switched from feeding on ice-associated prey (Arctic cod) to fish more typical of warm water (capelin). When neither cod nor capelin are abundant, chicks are fed primarily benthic prey and grow poorly.
