Brachyramphus marmoratus -1- Aug 15 Big Lagoon, Humboldt Co., Calif. Probably two birds heard calling while flying in or above the fog at 5:20 a. m. They flew inland south of camp, going in towards the headwaters of Maple Creek - about 5 minutes later 1 or 2 birds were heard flying overhead, out towards the sea, again above the fog. Murrelets have been heard going to and fro every morning about this same time. Aug 18 same locality - At 5:13 a. m. at least 2 birds were heard calling in the fog - one was giving a hoarse call, a little unlike the calls usually heard. Then about 5:45 - 3 were seen heading out to sea under the heavy fog blanket - as they went out and must have been about over the S end of the lagoon, 2 of them went into a steep power dive and were lost to view behind the trees. The fog was ascertained to beat about 1,000 feet elevation.
