Are some prey groups used more than others?ģ) What is the relationship between weather, prey abundance, prey use by peregrine falcons, and the reproductive performance (i.e. Research questionsġ) How does weather and habitat (terrain ruggedness, fresh water, tundra productivity) influence spatial variations in the abundance of various groups of prey ( Robinson et al. For my PhD research, I am investigating 4 questions regarding the foraging ecology and breeding behaviour of arctic peregrine falcons answers to these questions will help predict how peregrine falcons will respond to a changing climate in the Arctic. To fill these knowledge gaps I am monitoring a population of peregrine falcons breeding among the Coxe Islands at the Northern tip of the Melville Peninsula, Nunavut. However, little is known about the prey preferences or breeding behaviour of arctic peregrines in relation to prey abundance, so the implications of reductions in certain prey groups are hard to predict. Cold weather during precipitation events can reduce chick growth rates and survival of insectivorous birds, a major prey group of arctic peregrines ( 3), by limiting the amount of arthropods available to forage on ( 4). Temperatures in the Arctic are rising at almost twice the rate of the rest of the world ( 1) and summer precipitation has increased significantly over the last century ( 2). The arctic peregrine falcon ( Falco peregrinus tundrius) is a top predator with a prey base that may be affected by the impacts of climate change, which are more pronounced in arctic ecosystems than others. ![]()
