Status: Rare casual fall visitor east.
Documentation: Photograph: 19 Nov 2016 Omaha, Douglas Co (Brogie 2017).
Taxonomy: No subspecies are recognized.
Records: There are two records:
19 Nov- 9 Dec 2016 sub-adult female Omaha, Nebraska feeder (Brogie 2017).
3- 9 Oct 2018 adult male Fremont (in Saunders Co)
This first record was of one that appeared at the Robert Manning feeder in Omaha 19 Nov, when it was videotaped. Photographs and the video were examined by Sheri Williamson, who noted that ageing females at this time of year is tricky due to ongoing molt; however, she thought it to be a “subadult female”. The second was a brightly-colored male that was first seen 3 Oct 2018 at the Hill residence feeder across the Platte River from Fremont in extreme northern Saunders Co. It was seen by several observers through 9 Oct.
Comments: This species is generally resident along and near the California coast, but there are numerous records east of the Rocky Mountains scattered eastward to the Atlantic Coast (Williamson 2001, eBird.org, accessed November 2017). Adult males, such as the 2018 record above, are uncommon east of the west coast breeding range; of 29 records east of the Rockies and south to Kansas and Missouri, five were adult males, 15 were females or immature males, and 9 were unspecified (eBird.org, accessed 9 Oct 2018).
There are six records for South Dakota, five in the narrow window 12-26 Nov, and the other 28 Aug-30 Sep (Tallman et al 2002). In Kansas there are 12+ records in the period Aug through Jan (Thompson et al 2011). However, there are only two Iowa records, 31 Oct-25 Nov 2010 and 16 Nov 2015, both from Polk Co (Iowa Ornithologists’ Union 2017).
