Unfortunately have no visual or recorded evidence. Would describe the call as keeeit, one syllable, loud, gruff, bass (I'm a baritone, for me to imitate must go to bottom of my range), touch of rolling, repeated every few seconds in flight. Impressions were medium to large bird, circling at tree height, relatively fast flyer. Bit of a hawk/corvids mix to call. Thoughts?
