Journal R.E. Johnson 1968 May 25 Anchitka Island, Alaska (cont.) Black Oystercatcher - one on rocks breaking the surf, located 100 yds out from beach. Least Sandpiper - Charley Yarbrough recognised this small sandpiper by its notes. I only can vouch for its small size (definitely smaller than a Rock Sandpiper). There were two birds 100 yds out from shore on rocks breaking the surf. This is too far for me to identify these birds. 1st sighting this ys. Aleutian Tern? Again Charley was certain of this identity having seen the Arctic Tern with a bright red bill only the day before. However they (6) I'd guess were arctic terns. They were close but had strong back lighting & definitely could not be sure of the bill color, nor could I see the white on the forehead. The gray on the upper wing was darker than in Foresters Tern but having never seen either the Aleutian or Arctic Tern before, I can not judge which of these 2 species this gray shade matched. They were slender graceful birds & had a call resembling Peterson's description of the Arctic Tern, not the Aleutian Tern. Needless to say that I do not know which species this was. The Arctic Tern has been known on Anchitka (Kroq) & is a common breeder
