Various alarm calls from one of a pair, presumably near a nest. The higher pitched calls were given while the bird was both perched and in flight a little distance from me. The lower pitched calls were mostly given in flight, including in close proximity. Several wing whooshes can be heard as it dived at me. The other member of the pair tended to keep much more distant, and was mostly not vocalizing.
