    Studies using artificial nests or remote cameras have documented avian predation by red squirrels (Tamiasciurus hudsonicus). Although several direct observations of avian predation events are known in the northern range of the red squirrel distribution, no accounts have been reported in the southern portion. We observed predation upon a hermit thrush (Catharus guttatus) nestling by the Mount Graham red squirrel (T. h. grahamensis), an endangered subspecies living at the southern terminus of the distribution of the red squirrel.
