The Leach's Storm-Petrel is listed as a Species of Special Concern in Maine, and much of its ecology remains a mystery. The bulk of the North Atlantic population breeds in Newfoundland, where nest attendance has plummeted in recent years. The most recent population estimates for the Gulf of Maine are over 20 years old, and we have no information on the population trend. A repeat census will provide critical information on the conservation status of this shy little seabird.
