The Migratory Bird Count for Occoquan Bay Natural Wildlife Refuge is held each year in May. This year the count will be held on May 9.

This is the longest running annual spring bird count in this area. Held at the height of spring migration, these counts have averaged 130 species (with highs of 140 or more). Teams of volunteers conduct an area search, counting species and individuals.

Data is submitted for inclusion in a hemispheric database used by Partners in Flight  to chart the status and population trends of resident and neotropical migratory species.
