Check-out check traps on WR. It's clear, upper 40's - the moon
(<1/8 full is overhead). Good results this am - some traps closed
by Neotoma (<10%). Finished checking all traps by 0910h.
Summary of results on WR - P. californicus: 5 captures
P. tuwi : 14 " (new)
N. fuscipes : 9 " (new)
P. coyii : 1 "
Perognathus: 10 "
TOTAL 35 captures (2 new)
Went into town this am to get bait. Since the cost of rolled
oats has recently doubled (.80 c/lb, supposedly due to the drought),
I purchased unrefined rolled oats (stilled husk) at a
Food store. They run at 19 c/lb. The only difference is that
each oat grain is still in its husk. There should still be plenty
for the mice to eat inside the traps.
In the afternoon (1330-1530h) I set both BC and MC
drift fence traps. Additionally I put out min/max thermometers
in their wooden box shelters at the locations previously used
for weather monitoring. Each shelter is 0.5m above ground
level and placed facing north (maximum shade) on MC
& BC. On grid WR, the shelter faces southwest but should
still remain in the shade. I also set up and began
running the hygrothermograph on Grid WR below the maximum
thermometer. I'm doing this to compare against the min/max
and get some humidity readings.
While checking traps on BC drift fences I noticed traps
closed at 9:17. I must have overlooked there and 2 P. coyii
(# 04241 & 03408) were dead in the traps - shit!
