Data from: Evaluation of breeding distribution and chronology of North American scoters
Aim : North America's scoter species are poorly monitored relative to other waterfowl. Black ( Melanitta americana ), surf ( M. perspicillata ), and white-winged ( M . deglandi ) scoter abundance and trend estimates are thus uncertain in many parts of these species' ranges. The most extens...

Aim : North America's scoter species are poorly monitored relative to other waterfowl.
