The slowest flying bird is an anseriform bird called the walking duck (scientific name: Dendrocygna autumnalis). This bird is mainly distributed in South and Central America, with a wingspan of about 60 centimeters.
The flying speed of walking ducks is about 16 kilometers per hour. This is due to their bulkier bodies and short wings that are not suitable for fast flight. Walking ducks usually swim or float on water and can run quickly on land while also gliding through the air with ease, but they do not fly at high speeds for long periods of time.
It should be noted that different species of birds have different flight speeds, and their flight speeds are also affected by factors such as environment, climate, and season.
