JOURNAL At Kasook, on the Wkade River, North Slope Borough, Alaska 30 August Started T5, 11-14. This am beginning at 0600. Temperature a mild 8°C at 0600, rising to 13°C by 1100. Almost no wind, clear sky. Sunrise was among the most enchanting I have seen at Wkade, with each depression in the terrain filled with a thick morning fog. Very little bird activity: the most abundant numerous species was Calcarius, but even these were not common. As yesterday, all 3 Gavia spp. were conspicuous because of their incessant vocal activity. The warmer temperatures today appear to have set the stage for vocal display in many species: the 3 Gavia, both Lagopus, Calcarius lapponicus, Passerulus sandwichensis, and Boreotrichia leucophrys all sang. After coming in from the transects a cleared camp until the last of 3 flights at 1600. Then off to NML + done with Wkade River for 1978, and perhaps forever. See 1978 Wkade Ornithology accounts for description of spp. status.
