Dabbling duck movements to and from North Carolina and South Carolina, USA, to and from other states or provinces in study of highly pathogenic avian influenza A(H5N1) 2.3.4.4 virus, United States, 2021. Data are based on North American Bird Banding Program data collected during 1960–2021. Color intensities represent number of movements detected between a given state or province and North Carolina or South Carolina. Lines are positioned at the centroid of a given state or province. Bold border lines indicate administrative migratory bird flyways (from west to east: Pacific Flyway, Central Flyway, Mississippi Flyway, and Atlantic Flyway).
