Objective(s): To study the energy budgets, physiological changes and importance of body reserves in long-distance shorebird migrants in relation to migration, climate, survival and breeding and to investigate the migration routes used by shorebirds between their breeding grounds in the eastern Canadian High Arctic and wintering grounds on the European seaboard.

Project Description: Work by Dr. Morrison at Alert in the mid 1970's established the Knots and Turnstones breeding on northern Ellesmere Island migrate to wintering grounds on the European seaboard. Most migrate via staging areas in Iceland, though some of the population reaches Ellesmere via Norway. The internationally coordinated research program carried out over the last six years to study the migration, ecophysiology and energy budgets of Ellesmere migrants will continue.
