I believe these are three calls from Northern Harrier that I inadvertently picked up while recording Swamp Sparrow. The coloration frequency response for the harrier calls is probably not the best since they were probably off-axis of where I was pointing the shotgun mic, but I would note in the recording about 30s later that I was watching two harriers float by passing over the road so they would have been out over the sedge meadow where the swamp sparrow was and probably not too far off-axis. Looking at Birds of the World, this call seems to be a call that is often given by by female harriers ```in an effort to induce food transfers, hunting by the male, or to “solicit” copulation```.
