Very soon there was a chase, and they both flew away, the normal kind in pursuit of the allino. About 45 min. later the allino was back, perched in a maple tree. Don shot, it flew away. We walked a short ways into the nearby field, + saw this allino being chased by another bird in a sweepy circle, rather high. While writing, I have seen 2 ?, probably 2 ?
