The slate-colored dark-eyed junco is the only variation commonly found in the east, ranging from the East Coast to, but not including, the Rocky Mountain region. Slate-colored juncos can also be found throughout Canada and Alaska. This bird is easily recognized by its solid gray head, neck, back, and wings contrasting with a boldly white lower chest and abdomen. The bill is pale but may show a dark tip, and lighter gray females may show a faint brown wash over their back and wings. The range for the white-winged junco extends from the western Black Hills region of South Dakota through western Nebraska and eastern Colorado and Wyoming. Males may spend all winter in the northern part of the range, while females and younger males migrate south during the coldest months. This type of dark-eyed junco can be found from the Rocky Mountains to the Pacific Coast and as far north as the southern edge of Alaska. Populations may extend as far east as the western portions of Texas, Oklahoma, Kansas, and Nebraska. The pink-sided junco can be found in the western mountainous regions, with nesting areas in Montana, Idaho, and Wyoming. Its wintering grounds are further south, including Colorado, New Mexico, Arizona, and western Texas. At any time of year, however, pink-sided juncos may be found between those two extremes of their range. This type of dark-eyed junco has the most restricted range of any of the variations, and it is only found in southern and central Arizona and New Mexico, as well as western Texas. Gray-headed juncos can be found during the summer in Nevada, Utah, and Colorado, and during the winter in Arizona, New Mexico, and northern Mexico. Small populations may also extend as far as California and western Texas. Yellow-eyed juncos are found primarily in central Mexico, though they can stray as far north as the southernmost parts of New Mexico and Arizona.
