Aquila chrysaetos canadensis
Status: Uncommon regular spring and fall migrant west and central, rare east. Uncommon regular resident west. Uncommon regular winter visitor west and central, rare casual east.
Documentation: Specimen: UNSM ZM12988, 8 Nov 1912 Comstock, Custer Co.
Taxonomy: There are six subspecies recognized, five in Eurasia and one, canadensis, in North America and far northeast Russia. Nebraska birds are canadensis.
Spring: winter<<<>>>May 15, 15, 18
Dates above are away from the breeding range; there are only a few later reports, most of which represent sub-adults: 20 May 1978 Howard-Hall Cos, 20 May 1994 immature Lakeside, Sheridan Co, and 23 May 1994 Crescent Lake NWR, Garden Co.
Migration begins with adults in early Feb, peaking late Mar-early Apr, and continues with sub-adults through mid-May (Wheeler 2003).
Summer: Bruner et al (1904) stated that “years ago” it bred “quite generally over the state,” but that by 1904 its range was limited to the Pine Ridge area. Ducey (1988) noted breeding reports from Douglas Co in 1884 and possibly in Nemaha Co in the 1880s.
Currently Golden Eagles breed throughout the Panhandle, west of the Sandhills. As late as the 1980s, Golden Eagles nested further east, in Chase, Keith, Garden, Lincoln, and Hayes Cos (Busch 1979; Bennett 1973, 1975, 1986; Rosche 1994; Brown and Brown 2001; NGPC unpublished data). A comparison of the spatial distribution of nesting records from the 1970s and 1980s with the 2000s (NGPC, unpublished data) suggests the breeding range has continued to erode to the west in the Panhandle. However, Molhoff (2016) reported recent confirmed nesting in south-central Garden County and eastern Cheyenne County. Suggestive of a resident pair and possible recent breeding in Keith Co were two adults there 11 Aug 2007 (Stephen J. Dinsmore, personal communication). Similarly, sightings near Nenzel, along the Niobrara River in northern Cherry Co, are suggestive of breeding; there were sightings there 13 Jun and a pair was present 22 Jun 2002, and, earlier, an adult was near Springview, Keya Paha Co 25 Jul 1999 and a single was in Thomas Co 17 Aug 2014. In 2007, 20+ nests were located in the Panhandle.
There are a few reports in summer from the Panhandle in areas where breeding sites are not known; these are likely non-breeding sub-adults: 2 Jun 1996 Box Butte Co, Jul 1973 Sheridan Co, 30 Jun 1967, 17 Jul 1996, 25 Jul 1977 Garden Co, and 13 Aug 1992 Morrill Co. Breeding may not occur until birds are 4-7 years old (Kochert et al 2002).
There only additional summer reports away from known breeding areas are 12 Aug 1983 in McPherson Co and again there 22 Sep 2014.
- Breeding Phenology:

Fledglings: 2 Jun-12 Jul
Fall: Oct 3, 4, 8 <<<>>> winter
Early dates above are away from the breeding range. There are a few earlier reports, the more westerly of which are likely to be sub-adults which may have summered within the breeding range, or hatch-year juveniles, which may begin dispersing in late Aug (Wheeler 2003): 12 Sep 1992 Sheridan Co, 13 Sep 2007 juvenile Lake Ogallala, Keith Co, 16 Sep 1978 Garden Co, 25 Sep 1964 Adams Co, and 25 Sep 1990 Lincoln Co.
Fall sightings in the east occur every year; the Hitchcock Nature Center Hawk Watch in western Pottawattamie Co, Iowa, averages 19 Golden Eagles per year, with a poorly-defined peak from late Oct through Nov. Padelford and Padelford recorded Golden Eagles in the Missouri Valley 28 Sep-9 Nov in three of five years in the early 1990s.
Winter: Breeders are probably resident year-round (Rosche 1982; Palmer 1988; Kochert et al 2002), but individuals, mostly sub-adults, may appear anywhere in the state during the winter months. Numbers are fewest in the east, where there are about 65 reports in the period 6 Oct-30 Apr, fairly evenly spread throughout the winter period. The winter 2012-2013 saw a major move eastward, including a surprising four adults: Dodge Co 11 Dec, Otoe Co 18 Jan, Washington Co 3 Feb, and Butler Co 15 Mar. Even in westerly North Platte, the 3+ reported 2012-2013 constituted an “irruption” (T.J. Walker, personal communication). Two adults reached the east in 2014-2015: Otoe Co 5 Dec and Lancaster Co 30 Jan, and one was in Burt Co 1 Jan 2018.
Midwinter Eagle and Waterfowl Surveys conducted by NGPC 1992-98 yielded statewide totals for Golden Eagles ranging from 15 in Jan 1992 to 35 in 1995 (Cortelyou 1992, 1993; Dinan 1995,1996); methodology of these counts may have allowed for inadvertent inclusion of young Bald Eagles.
