Trying to find movie name

Could this be the Shadow of Chikara (1977) - https://www.imdb.com/title/tt0078240/ It did have alternate titles as well - https://www.imdb.com/title/tt0078240/releaseinfo/?ref_=tt_dt_dt#akas Two former Confederate captains set out to recover diamonds hidden in the mountains of Arkansas but a native spirit named Chikara is said to protect the sacred mountains against intruders. This starred Sondra Locke (who is blonde but does not particularly look like Sissy Spacek) I found a forum post on the internet via a search of "supernatural western eagle" that seemed to match up.
