Trying to capture you

I have these 3 very large birds that circle my field starting around dusk. I thought perhaps to capture them in silhouette. I’m still not sure if they are turkey buzzards or eagles. They soar like Eagles and nest in the tall trees in my field. They fascinate me because sometimes when I let Angel dog out in the back yard she seems to attract them. When they get close enough they see she’s well fed. ツ They fly by. ツ
