Two Songbirds And A Mouse
Two different kinds of signs — droppings and incisor marks – reveal the inhabitants of a woodshed during a very cold spell. The partially-eaten, shelled acorns have tiny grooves in them (difficult to see well in photo, my apologies), made by the incisors of a very small rodent, likely a White-footed Mouse or a Deer Mouse (the animals, much less their signs, are extremely difficult to tell apart, even if both species are sitting in front of you).
The two remaining signs are droppings from birds that sought shelter overnight inside the shed. Mourning Doves have very distinctive scat — individual round droppings, each about 1/4″ in diameter, consisting of coils of dark, solid waste which sometimes have a dollop of white uric acid on top.
The third and last sign is also bird droppings, but unlike the Mourning Dove’s, these are white and log-like. If you’ve been inundated with Dark-eyed Juncos this winter, you should be able to find these on the ground where they congregate.
