Native to western North America, the house finch was introduced to Hawaiʻi in the mid-1800s and are now common on all main islands. They are most common on the leeward or dry sides of the islands. A medium sized finch (about 5 ½ inches), house finches are mostly gray-brown with a boldly streaked breast and males have a red/orange head and breast. House Finches sing a long, jumbled warbling song composed of short notes that often ends with an upward or downward slur.
