The Canadian field-naturalist. 1999 Notes 287 Albino Leach's Storm-petrel, Oceanodroma leucorhoa, in Nova Scotia Jonathan Russell Oxley Biology Department, Acadia University, Wolfviile, Nova Scotia BOP iXO, Canada; E-mail: 007845o@acadiau.ca Oxley, Jonathan Russell Oxley. 1999. Albino Leach's Storm-petrel, Oceanodroma leucorhoa, in Nova Scotia. Canadian Field-Naturalist 113(2): 287-288. A complete albino Leach's Storm-petrel, Oceanodroma leucorhoa, chick was discovered on Bon Portage Island, Nova Scotia. It appears to be the only known record of albinism in this species. Key Words: Leach's Storm-petrel, Oceanodroma leucorhoa, albinism, Bon Portage Island. On 21 August 1997 a 33 day-old (± 3 days) com- pletely albino Leach's Storm-petrel, Oceanodroma leucorhoa, chick was discovered on Bon Portage Island, Nova Scotia. (43°28'N, 65°45'W). Leach's Storm-petrels are small burrow-nesting Procellari- formes that rear a single chick each breeding season. (82.5% fledging success on Bon Portage Island dur- ing the 1997 breeding season, unpublished data, author) Normal chicks are hatched with dark blue- gray natal down which is eventually replaced with black juvenile plumage except for a white rump patch. This latter plumage is also found in the adult birds. The albino chick was 1 of 146 petrel chicks stud- ied in a colony estimated at 45 000 breeding pairs (unpublished data, author). All existing natal down was pure white and the legs, feet, and bill were flesh colored. The iris was deep red. These albinistic char- acteristics remained as juvenile plumage replaced original down. Color photographs were taken at 34 and 64 days of age (see Figures 1 and 2). I could find no literature regarding albino petrels and presume this to be the first record of its kind (C. E. Huntington, Bowdoin College Biology Department, Brunswick, Maine 04011 USA, personal communi- cation). On 23 August, the wing chord of the albino chick measured 76 mm and the tarsus length 23.9 mm.
