The polar bear Ursus maritimus feeding in a seabird colony in Frans Josef Land
Open accessAbstract
During the second half of August 1992 polar bears were observed feeding intensively in the little auk Alle alle colony on Rubini Rock, Hooker Island, Frans Josef Land. They dug out nests eating eggs, chicks and adult birds. Their activity results in both worsening the breeding conditions and decreasing the breeding success of the little auks. The polar bear has not earlier been known as a little auk predator.

Arctic foxes and polar bears often overlap in habitat use with nesting seabirds at islands and mainland sites throughout the Arctic, where they will occasionally forage on eggs, chicks, and adult seabirds.
“For example, arctic foxes ( Vulpes lagopus ) (e.g., Larson 1960; Eide et al. 2005) and polar bears ( Ursus maritimus ) (e.g., Stempniewicz 1993; Dey et al. 2020) often overlap in habitat use with nesting seabirds at islands and mainland sites throughout the Arctic, where they will occasionally forage on eggs, chicks, and adult seabirds.”

The opening passage (p. 1) says polar bears often visit Arctic islands with seabird colonies. The paper’s summary (p. 1) and Observations (p. 2) document bears eating little auk eggs, chicks, and adults at one island colony. It does not establish the polar-bear claim for mainland sites throughout the Arctic. (LLM, conf=0.84)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
