What exception to typical migratory patterns is observed in the Wood Duck population using the Pacific Flyway?
Answer
Roughly three-quarters of the Wood Ducks remain non-migratory year-round
While it is generally true that northern Wood Duck populations migrate south to escape harsh winter conditions, the Pacific Flyway presents a significant deviation from this rule. Within this specific migratory corridor, a substantial majority of the Wood Ducks—approximately seventy-five percent—do not engage in seasonal migration. These individuals establish residency year-round along the West Coast regions, contrasting with the more migratory tendencies seen in populations further north or those utilizing the Atlantic and Gulf Flyways.
