Cogswell 1949 Nuttallornis borealis Aug. 10 of Big Lagoon, Humboldt Co. Calif. about 1:30 p.m. collected one from its perch in top of 35 ft. Sutha spruce above t[illegible] & elder thicket up, tangle on lower hillside about 1½ mi. from SE end of lagoon. There are scattered Douglas fir & some spruce nearby which are much taller; also a few tall alders. The brush is the dense deciduous thicket which extends part of the hill W. of maple creek. I watched the bird dive from its perch once & the pick up an insect from near the brush canopy. Aug. 11 [Upon skinning this bird next day it was found to have 2 black & yellow-banded wasps & many other miscellaneous insect fragments in its stomach]. Aug. 8-19 This species was fairly common in Spruce-alder forest and in the 3 year old burn; I was also noted in wet Alder-maple forest & 1 in Red wood forest. Aug. 14-26 French Camp, 3100 ft., Humboldt Co. Calif. Common open Douglas fir - Tan oak forest near camp, in the burned over area & at borders (only) of more moist coniferous forests. A nest, placed about 60 ft. up & next to the trunk of a 75 ft. Douglas fir on the edge of the burned area, held large young being fed by both parents on Aug. 21. The "song" ("what pees you") was given only occasionally during this period; but the "pip-pip-pip" note was incessant.
