Lehner P. 1965 Jan. 15 got up to start guywire census at 7:30 A.M.; set out 5 sets (2 each) of the moisture blocks, one on surface (denoted by red tape) and one at the 6" depth (denoted by blue tape) - the blocks are gypsum, designed to soak up moisture and therefore change resistance - a known current is fed into one side of the block and a meter reads the resistance in ohms or the % humidity; at 9:30 A.M. a Christmas Island Shearwater was sitting in some Portulaca near the concrete slab on the east shore; Norm and Binion took 3 Berlese samples; there were 2 new Grey-back eggs on the pier (total of 10) and a total of 2 on the islet; there is also a new Frigate bird egg on the islet; a Golden plover repeat # 642-01170 was caught in the mist net; we ran a shorebird count on Sand getting the following figures: 83 Golden Plover, 44 Ruddy Turnstones and 4 Wandering Tattlers; there appears to be 5 Blue-faced Boobies using the guywire bases.
