Falco scarverius columbarius Lake Umbagog, Maine. Chases a Sandpiper. 1896. Sept.5. Keeping on down the river to-day, I heard a Sandpiper peeping shrilly and turning saw a single bird coming directly towards me with a Pigeon Hawk in close pursuit. The Sand- piper was evidently doing his best but the Hawk overtook him with the utmost ease just as the two were within about 50 yds. of me. The Sandpiper doubled sharply, however, at the last moment and the Hawk overshooting his mark by some ten yards turned and quickly closed again. Again the quarry doubled and this time the Hawk abandoned the chase in evident disgust and flew straight away over Leonard's Pond while the Sandpiper alighted with his companions who had not risen at all during the episode.
