To generate counts of migrating birds for use in long-term population monitoring, especially landbird species not monitored by current breeding or winter surveys; To carry out cooperative research projects on the ecology of migrating birds.
Méthodologie
Plan d’échantillonnage

Méthodes de terrain
Combination of standardized daily captures, census, visible migration counts and other observations resulting in a daily estimated total for each species.
Méthodes d'analyse
