Thud 1952 Pt. Barrow, Alaska September 13 Banking on grid. Traps attacked by Snowy Owl. 2 Bunting killed 1 banded +1 unbanded - traps bent up as badly as when dogs bother them. A similar instance occurred on afternoon of September 12th at about 6:00 pm. One owl smaller than the Snowy Owl was noted in company with the Snowy Owl - its identity in question owing to darkness but did not appear to be a young Snowy Owl. I have broken up the grid trap arrangement owing largely to the concentration of Bunting about the 1st row of traps (#6+7 in particular) and have concentrated the 3 funnel traps (G5,6,7) all four clover leaves and I moved to funnel trap. Visited Johnny Bottum's magnetic station and also the Bureau of Standards atmosphere set up, continuing to run soil samples from Butlin's Mana. Day overcast light powder snow early this morning ponds with light ice shut in them. Chironomid larvae, especially large red one easily demonstrable in mud in bottoms without vegetation. One of the soil samples from Butlin Mana (ice from high polygon - mainly grass area) yielded large number of Staphylinid and Oribatid adults plus usual collembola.
