It’s May 4th Bird day, also celebrated in the United States on January 5 of each year, International Migratory Bird Day is celebrated on the second Saturday in May. Oil City, Pennsylvania Superintendent of Schools, Charles Almanzo Babcock, established the first such holiday in 1894.
The health of the global bird population is a reflection of and early warning system for our wider ecological health, and current research indicates that up to 12% of all species of birds may be at risk of becoming extinct in the next century.
Though human activities have allowed the expansion of a few species, such as the Barn Swallow and European Starling, they have caused population decreases or extinction in many other species. Over a hundred bird species have gone extinct in historical times.
