You can spot dark-eyed juncos (Junco hyemalis) wintering at Red Rock Canyon in shrubs and thickets. These small birds belong in the sparrow family (Emberizidae) and differ in coloration depending on which subspecies you see. However, they all share white outer tail feathers and pink bills. In Red Rock Canyon, you are most likely to see the Oregon subspecies; they can be identified by having a dark head and a red-brown back & flanks. During the winter dark-eyed juncos often feed on seeds and grasses and then switch to an insect-heavy diet in the summers.
