Seasonal Diets of Newfoundland Martens, <em>Martes americana atrata</em>

We analyzed scats (n = 679) and stomach contents (n = 25) collected from 1980-2003 to assess the relative frequencies of food types utilized by Newfoundland Marten ( Martes americana atrata ) during summer and winter. Meadow Voles ( Microtus pennsylvanicus ) were the most prevalent food item occurring in 80% and 47.5% of samples from summer and winter, respectively. Apart from Snowshoe Hares ( Lepus americana ), which occurred in 28% of winter samples, all other food types occurred in <16% of samples during each season. Diet breadth was widest during winter and may be related to a lower availability of Meadow Voles during this time of year. Erratum included.
