Cogswell 1949 59 Journal Big Lagoon, Humboldt C., Calif. Aug. 13. Caught the following in my traps in the Redwood forest on slope N. of camp at an altitude of about 350 ft: 1 - young Peromyscus maniculatus 2 - Zapus trinotatus (I kept alive) (see species) account) 1 - Sorex pacificus " .." About 8:45 A.M. I walked along Maple Creek to its mouth at the SE end of Big Lagoon (see map p. 72A). The marsh vegetation is of tall Scirpus sp. on the muddy banks and over flats which are wet but not under more than 6 miles of water at present. There is americana? + cleodanes. a border of a smaller Scirpus along the * steepers stream banks (mud); and there are extensive patches of a definitely triangular- Scirpus robustus Pursh. -stemmed sedge (= S. campestria B102) occurring on the tall similar ground as, Scirpus, but each separate stands. The shallower channels (to 3 1/2-4 ft.) are mostly filled with Potamogeton sp.? ex- cept where the bottom is of sand or gravel. Birds noted in this area were: Podilymbus podiceps - 1 Anas platyrhynchos - 6+ Anas acuta - 30+ Anas cyanoptera - 29 (or? design) Cathartes aura - 2 (flushed from gravel bar) * Porzana carolina - 5 (I collected flies board) Jutela americana - 2 Charadrius vociferus - 2 Squatarola squatarola - 10 (flying over, with ducks) Actitis macularia - 5 Erolia minutilla - 20+ Cremetes mourii - few *Chaetura vauri - many Hummingbird sp? - 1 Dribopatreine bicolor - many Hirundo rustica - 5+ Progne subis - 2 *Telmatogetes palustris - many agelaius phoeniceus - 2+ Charpodacus mexicanus - 14? melodica melodica - many (* = see species account)
