\nPeregrine falcon (Falco peregrinus)\u00a0populations around the world experienced massive declines during the 1960s and\u00a070s due to organochlorine pesticides moving up the\u00a0food chain, causing egg shell thinning. The deleterious effects of these\u00a0pesticides on the Arctic peregrine falcon (F.\u00a0p. tundrius) \u2013 a subspecies that breeds in\u00a0the Arctic regions of Canada, the USA, and Greenland \u2013 received less\u00a0documentation than other subspecies. However, tissues taken from Arctic\u00a0peregrine falcons breeding around Rankin Inlet, Nunavut, in the early 1980s\u00a0indicated that organochlorines were present in\u00a0Canadian Arctic ecosystems. Yearly monitoring of the Rankin Inlet population\u00a0has been ongoing since 1982, and data show that pesticides loads have been\u00a0declining and are now below toxic threshold levels. Nevertheless, the number of\u00a0chicks produced by this population is declining each year and the specific\u00a0cause is unknown. Our research group (www.arcticraptors.ca<\/a>) is currently examining a series of hypotheses\u00a0to determine the cause of the decline in productivity.\u00a0For my PhD research, I am working with Government of Nunavut\u00a0biologists to establish a study complimentary to that in Rankin Inlet, 800 kms further north near the community of Igloolik.\u00a0Our overarching goal is to determine the influence of variations in prey\u00a0abundance on the breeding behaviour and foraging ecology of Arctic peregrines\u00a0falcons. Arctic peregrines feed on a variety of prey including song, shore and\u00a0marine birds, and small mammals, but little is known about how peregrines\u00a0select from this assortment of prey as the availability of each prey population\u00a0fluctuates and how these fluctuations influence breeding performance.\u00a0 My PhD dissertation will include 4 main
\nresearch questions:<\/p>\n

1.\u00a0\u00a0\u00a0\u00a0 Which\u00a0landscape features do peregrines use to select foraging sites and how do they select from a variety of prey types?<\/p>\n

2.\u00a0\u00a0\u00a0\u00a0 How do\u00a0variations in different prey assemblages influence breeding behaviour and\u00a0performance?<\/p>\n

3.\u00a0\u00a0\u00a0\u00a0 Does\u00a0stress induced on the wintering grounds and during spring migration north to\u00a0the breeding grounds influence breeding behaviour and performance<\/p>\n

4.\u00a0\u00a0\u00a0\u00a0 Do\u00a0back-pack style GPS transmitters influence breeding behaviour and
\nperformance?<\/p>\n
