Migration is the regular seasonal movement, often north and south, undertaken by many species of birds. Migration is marked by its annual seasonality and movement between breeding and non-breeding areas. [16] Nonmigratory bird movements include those made in response to environmental changes including in food availability, habitat, or weather.

- Species Conservation Statistics
The Species Migration Maps can be used to understand the movements of individual birds and the entire population as they migrate between seasonal ranges.
The Species Migration maps are made possible by the generous contribution of data and expertise from the research community and our partners. Tracking data that show individual pathways were contributed by hundreds of researchers.
Global Population Estimate
The global population size is an estimate of the number of breeding age individuals that occur across the entire range of a species. Learn more about the Avian Conservation Assessment Database here.
Continental Conservation Status
Based on quantitative criteria, the continental (US/Canada) conservation status is assigned to species that are designated as: Highly Vulnerable and in Urgent Need of Special Attention (Red List), Range Restricted and Small Populations in Need of Constant Care (Yellow Watch List R), Steep Declines and Major Threats (Yellow Watch List D), or Common Birds in Steep Decline.

Global IUCN Red List Category
Based on quantitative criteria, the global extinction risk of each species has been assigned to one of the following levels: Critically Endangered, Endangered, Vulnerable, Near Threatened, or Least Concern. Learn more about the IUCN Red List here.
