Main Foods Taken
Based on limited data, appears to feed on squid and shrimp (5).
Food Capture and Consumption
Presumably feeds by seizing prey at or just beneath the surface, as do other species of gadfly petrels, though direct observation of foraging Bermuda Petrels has not been reported. Birds are not attracted to ships as are other seabirds.
Major Food Items
Very little published information. Green excreta at nest sites suggest that small squid make up part of the diet during the chick-rearing period, and pink excreta indicate that pelagic shrimp are also commonly taken (5; D. B. Wingate, in litt.). Stomach contents of a fledgling female Bermuda Petrel received by William Beebe 8 June 1935 were examined by Robert Cushman Murphy, who noted "17 beaks of cephalopods as well as several crystalline lenses of the same organisms" (5).
