Dr. Milton Marcilio is an amateur ornithologist who has more than 50 years of experience as a psychiatrist in and around Toronto, Canada. Dr. Marcilio has managed his own private practice since 1982. For amateur ornithologists and bird enthusiasts of all kinds, there is no greater journey to embark on than a Big Year. Simply put, a Big Year challenges each participant to see and catalogue as many different species of bird as possible between the first and last days of the calendar year. For individual birders, a Big Year can include world travel or be limited to the forests of one’s hometown. The competition is run primarily on the honor system, although serious birders are encouraged to take pictures and travel in large birding groups if they plan on pursuing a Big Year record. Without documentation, rare or otherwise unlikely sightings may be rejected by birding authorities. Sandy Komito set the current Big Year record in 1998, when he recorded seeing 745 unique species. Amateur ornithologists can alternatively take part in a Big Day or Big Month competition.
