World Migratory Bird Day is observed twice a year during the second Saturday in May and again on the second Saturday in October. The goal is to raise awareness of issues affecting migratory birds and to inspire action around the world to take measures for their conservation.
Migrating birds may fly from 15 to 600 miles or more per day
during migration, depending on when they are migrating, how far they have to
go, and the conditions they face along the route. While most migrating birds
fly at heights lower than 2,000 feet, birds have been recorded migrating at up
to 30,000 feet high, a record held by the bar-headed goose. Hawks, swifts,
swallows, and waterfowl migrate primarily during the day, while many songbirds
migrate at night, in part to avoid the attention of migrating predators.
