International Migratory Bird Day
Saturday is International Migratory Bird Day, and there are few better days for bird-watchers to look to the skies for feathered friends returning after the winter.
The date --- the second Saturday in May in North America --- is chosen to coincide with the thick of the annual migration, which usually sees tens of millions of birds of varying species making their way back to the north. The idea of a day to celebrate migratory birds originated with the Smithsonian Migratory Bird Centre as a way to promote conservation.
While you may see more bird activity around this time of the year, the majority of the migrations will usually take place at night, with birds stopping during the day to rest and recover their strength before continuing on to breeding and nesting grounds.
