Atlas note: With spring upon us, several local species have already started their breeding behaviour. Migrants are arriving daily and staking out territory before nesting. Observing and reporting this activity to the Ontario Breeding Bird Atlas provides essential information for Canadian researchers, scientists, government officials and conservation professionals that will help guide environmental policies and conservation strategies across Ontario for years to come. The Atlas is conducted every 20 years and is five years in duration. Participation in this once in a generation community science opportunity is straight-forward and as easy as simply noting the presence of a bird.
