This species is often reported in the central and eastern US where it is generally considered escaped or released, as in Nebraska (eBird.org, accessed Mar 2024). Wild birds occur in small numbers in winter on the Aleutian Islands and Pribilof Islands (Carboneras and Kirwin 2020), and there are at least 10 records of presumed wild birds (as well as non-wild birds) for Pacific Coast states from British Columbia south to California, as well as single records of presumed wild birds for Idaho and Wyoming (eBird.org, accessed Mar 2024).
