First ever recorded sighting in Yellowstone by Terry McEneaney on August 9, 2002.; Data Source: NatureBib Bibkey ID: 590284, Nature Notes: Recent Additions to the Yellowstone Bird Checklist, and Raven Predation of Grebes in Yellowstone Science, Summer, 2004.

Although this species is native to North America, it is not endemic or indiginous to YNP. Its occurrence in the park is essentially accidental and well outside its accepted range (McEneaney 2004, NatureServe 2006, Sibley 2003). This suggests that it does not, and probably never did, regularly occur in the park. Thus, its nativity in the park is uncertain and could be classified as unknown or non-native.; Data Source: Doug Keinath-Lead Zoologist-Wyoming Natural Diversity Database
