in morning. Total catch 9 Meristus, 10 Joreh, 4 Kethro, and 1 Mna. Heard gust-bored and saw many 2 red-wings apparently with territories. Wood rat in house where we slept (on porch). at 10 p.m. found a Seeloborne between boards in a pile of lumber. Although outside temperature was not cold he seemed torpid. Brent put some nest boxes around the good Meristua marsh NE of San Rafael. I lifted a piece of draft paper in the marsh and found a Joreh and scat of straw and coarse stone—much coursier than mouse nest. The Joreh escaped. The Solvornia is becoming more prevalent, but still rather dead-looking. april 1 Left 3 p.m. with Louis Focho for Merostua in Marin Co. Set about 130 Heronous in the San Chester Marsh and 70 in the first marsh east of Marin co. Airport (NE of San Rafael). at 10 p.m. had 6 Meristua and a few Kuthro. Saw 1 bat in brick piles (looked like M. yunnansuui) and caught a couple of Hyla. York—lighted for brush substitutes but saw none. april 2 Total trip score 12 Meristua (not counting 2 that escaped when bucket upset), 7 Kethro, 1 Mna, 1 Joreh. Looked at Brent's nest boxes 3 1/2 mi. NE San Rafael: (Seeloborne in 1, water in 4, nothing in others.
