Abstract
Aberrant colouration in birds is relatively common but melanism occurs infrequently. We report an observation of a melanistic Razorbill Alca torda attending the nesting colony at Machias Seal Island, Bay of Fundy in 2022 and 2023. This is the third reported occurrence of a melanistic Razorbill and the first in over 100 years.
