World Migratory Bird Day is officially celebrated on the second Saturday in May (May 11th in 2024) as migratory birds journey to nesting sites and on the second Saturday in October (October 12th in 2024) as they return to wintering areas.

• Birds that are in the process of migrating can travel long distances — some of them up to 15,000 miles or more! 
• The highest flying migratory bird is the bar-headed goose, which reaches altitudes of around 5.5 miles above sea level. 
• The theme of World Migratory Bird Day 2024 is 'Protect Insects, Protect Birds.'
