Parabuteo unicinctus harrisi
Status: Rare casual fall and winter visitor west and east.
Documentation: Specimen: HMM 2895, 28 Oct 1922 Elkhorn, Douglas Co.
Taxonomy: There are two subspecies, harrisi of southwest United States south to Colombia, Ecuador and Peru, and unicinctus of Colombia and Venezuela south to northern Argentina and Chile (Gill and Donsker 2017). The Nebraska records are presumed to be of harrisi; northward vagrancy of unicinctus is unknown.
Fall and Winter: There are five records:
26 Oct 2012 Lancaster Co; road-killed bird photographed by Mrs Jon C. Barber (Brogie 2013)
28 Oct 1922 Douglas Co (cited above, see Comments)
5-9 Nov 2017 Niobrara River adjacent to Niobrara SP, Knox Co (Brogie, in press)
16 Nov 2017 Swanton RA, Saline Co; possibly same bird as preceding (Brogie, in press)
13 and 27 Jan 1995 Stateline Island, Scotts Bluff Co (Gubanyi 1996; Silcock 1995).
Comments: The photographs of the two records in 2017 did not allow determination of whether the same bird was involved, although the subsequent presence of a Harris’s Hawk in northeastern Kansas 27-29 Nov is strongly suggestive of a single bird making its way south from Knox Co. There were no other northerly sightings on the Great Plains that might have indicated a general northward dispersal movement.
The 1922 specimen cited above was shot by a hunter “while he was shooting ducks in a blind at Elkhorn, Douglas Co. It was mounted in Omaha and secured by Mr. A.M. Brooking for his collection, where it is #2895” (Swenk, Notes Before 1925).
This species regularly occurs from central Texas southward. Of the states surrounding Nebraska, only Kansas has records, seven in the period 17 Nov-7 Jan, plus a spring breeding record in Meade Co (Thompson and Ely 1989). Lending credibility to the Nebraska record in early 1995 was the appearance during winter 1994-95 in Oklahoma, Kansas, and Colorado of several Harris’s Hawks; three in Oklahoma and one in Kansas were observed beginning 26 Oct and were seen through 21 Jan (Grzybowski 1995), and two were in Colorado 17 Dec-4 Feb (Kingery 1995). Another 1995 record was of one in Columbia, Missouri, Feb 1995 that was photographed and the record accepted by the Missouri Records Committee; it may have been there for several months (Mark Robbins, pers. comm.). Harris’s Hawks are commonly kept as falconry birds and occasionally escape. Any Harris’s Hawks observed in Nebraska should be closely scrutinized, especially for the presence of jesses.
