The dark-eyed junco (Junco hyemalis) is a species of junco, a group of small, grayish New World sparrows. The species is common across much of temperate North America and in summer it ranges far into the Arctic. It is a variable species, much like the related fox sparrow (Passerella iliaca), and its systematics are still not completely resolved.

By 1889, this bird was very rare, though it could still be found in small flocks in the higher forests.
This list of bird species introduced to the Hawaiian Islands includes only those species known to have established self-sustaining breeding populations as a direct or indirect result of human intervention. A complete list of all non-native species ever imported to the islands, including those that never became established, would be much longer.
