Cogswell 1949 Journal 68+ Big Lagoon, Humboldt Co., Calif. Aug. 18 (cont.) In the gravel algae-lined pools in the stream in the burned-over area, tadpoles of Bufo were abundant as well as small fish. Birds noted were as follows: cathartes aura - several Sophortyx californius - heard alttity maculatus - 2 columba fasciata - 15+ cheetua vauxi - many Selasphorus sp.? - several megacycle allegon - 1 (near bridge) toloptis calla - 2 Dryocopus Hyletomus pileatus - 1 * Sphyrapicus varius - 1 im. Dendrotocus villous - 2 " pubescens - 2 * Empidonax troellii - 3+ # Contopus richardini - 10+ Mittallornis forestis . 5 swallow sp? - several Brogne sedes - 30+ Corvus corax - 2 * Cyanocitta stilleri - 2 Parus rufescens - 5+ Chamea fasciata - many Troglodytes aedon - 1 Trindis migratorius - several Hylorilla instulata - 3 Sagulus setrepa - several (in conifers near bridge) Bombayilia cedronum - several varmivors celata - 1 Dendroica aestiva - 1 opsornis tolneij - 2 * Geothlypis trichas - 1 Wilsonia pusilla - many Paranga ludoviciana - 3 # melanocphala thecticus - 3+ * Carpodacus purpurus - 1 Spinus pinus - several " tristis - many Loxia curvirostra - 4 Spizella passerin - 1 im. Tontirichia leucophrys - several melospiza melodia - many. Aug. 19 Since we are moving camp today I will summarize the area around Big Lagoon which I have covered, insofar as its various aspects of topography, climate, and vegetation relate to vertebrate animal distribution probably. The uplands in this region were all originally covered with coniferous forest except certain far seaward slopes with poor soil, as, e.g. the area farther N. on the map inserted at the end of today's journal entry. Logging, both selective and clean cut plus much subsequent burning has altered the vegetation after p. 72.
