註釋This report describes a model used to estimate the energy requirements of seabirds in eastern and Arctic Canada. The model integrates data from intensive studies at breeding colonies with extensive observations at sea, using bioenergetics equations as a bridge. It is run independently for small geographic cells, then aggregated into oceanographic zones. The basic data used in the model include the PIROP shipboard counts of birds at sea used for the Canadian Wildlife Service's atlas of seabird distribution; breeding season counts at major colonies; life table estimates of nonbreeding populations; and body mass measurements, from geographically appropriate sources where possible.
