These staging areas can be heavily used and are potentially critical to the survival of the migrants. This paper presents a method for estimating the number of individuals using such an area and their average residence time. The estimator is based on daily population estimates and records of repeat sightings of identifiable individuals. Its application is illustrated with observations on a population of migrating birds, some of which could be identified from bands that were readable from a distance.

We also document Canada Goose introductions and consider the status of these exotic, ‘resident’ birds, their dispersal, and population growth. We conclude that before the introductions, the Canada Goose was only a rare breeding bird on the northern half of Vancouver Island.
