Dec.19 Sears Point Road, 6 mi NW Vallejo,
coved mounds rising 2-3 feet above the general level of
the marsh and other traps along the edge of the marsh,
total of 70 traps. Rudd set out about the same number
on the mounds and each of us set out four traps in
a small marsh inward for a Baccharis-covered bank.
Noted western gull (1) Marsh Wren, Song Sparrow,
and a flock of +20 House Finches in Bacchasis. At sunset
(5:00 PM) flock of 16 White Pelicans in marsh across road.
Flocks of Pintail & Shoveller + one Canvasback.
Dec 20. Rudd picked up the traps; I did not go with him. The catch in
his traps was microtus 1
Sorex 8
Reithrodontomy 17
mus 6 while mine on the mounds was
Reithrodontomys 8
mus 9
Sorex 2
microtus 1 and on the edge of the marsh,
Reithrodontomys 1 }
mus + { 33 traps
Total 57 (my total for 74 traps was 25)
Rudd set his traps more carefully, specifically seeking
Sorex runways or placing the traps deep in the Salicornia
whereas I placed many of mine on open ground. There
was ice on some of the brackish pools according to Rudd.
The mounds were an estimated 30 feet from the edge of the
marsh perhaps closer to 30 feet in some places.
