The autumn diet of the edible dormouse Glis glis Linnaeus, 1776 in nor
thwest Spain was investigated on the basis of analysis of the stomach
contents of 32 individuals captured in September and October of 1985 a
nd 1986. Remains of Quercus robur scorns and Corylus avellana hazelnut
s accounted for 86.5% of the total dry weight of the 32 samples, while
blackberry remains accounted for 10.2%. Remains of vegetative plant s
tructures (leaves, etc) accounted for only 3.3% of total dry weight. I
nsect remains were frequently present, but in very small amounts (abou
t 0.01% of total dry weight]. Dormouse hairs and ectoparasites were al
so frequently present, presumably as a result of accidental ingestion
during grooming.
