Welcome to the Partners in Flight databases, managed by Rocky Mountain Bird Observatory. Please use the links below to visit the Species Assessment and Population Estimates databases. These databases were developed from the voluntary collaboration of more than one hundred ornithological experts to provide a standardized and transparent system that allows the comparison of conservation status and population estimates at multiple geographic scales for North American landbirds.
