Trevor Cuthill took these photos of a field mouse that had been caught in a Ketch-All trap, that then got its nose stuck in one of the ventilation holes. This was highly unusual. The mouse apparently poked its nose too hard through a hole, and got it stuck. Trevor pried one of the vent holes open to free the mouse, as its nose was swollen. He then released it, but it was very weak and injured, and he doesn’t think it survived. In any case, here are the images.

These photos show where bats were roosting in a house in Forest Meadows.
- They found ample living space under the roof tiles, along the roof edge of this very high roof line.
- Bats were also abundant under the corner trim, used to seal rather poorly formed corners.

This home in Sugar Pine had a water leak. A company came out and did a repair, cutting a large hole through the sub-floor, to allow drainage. They removed the insulation to allow it to dry out. But they never bothered to repair the hole they made.
A raccoon found the hole and moved in. That is when we were called.
Jason also found a raccoon latrine under the house.

The autumn of 2018 was a mast year for acorns in the Sierra Nevada foothills. The valley oaks, Quecus lobata, on my property, in Columbia California, produced prodigious quantities of acorns. I had noticed some size variation between the valley oaks located in different parts of the property, and did not think much of it. When I was at the massive house fly invasion job, I noticed that the acorns there were gigantic, far bigger than those at my house.
These giant acorns were coming off large valley oaks that grew along a year-round stream. The stream, on a cattle ranch near Chinese Camp, was fed by a spring, and it even had minnows in it, California roach, a fish that can survive in intermittent streams. A couple of the valley oaks on my property grow along a season creek, which had not had water since spring.
It appears that acorn size may be related, at least in part, to the water available to the tree when the acorns are growing.
These photos show the remarkable size variation in valley oak acorns.
Valley Oak A is from the Chinese Camp trees, fed by a year-round creek.
Valley Oak B is from across the street from property, from a huge and old valley oak growing alongside a season creek. The creek had water in the winter and dried up mid-spring.
Valley Oak C is from my property, from a somewhat smaller valley oak, and has larger acorns than the largest of my oaks. It is more downhill from “B”.
Valley Oak D is from across the street from my house, nowhere near a creek, uphill from the other oaks. IT appears to be the most water starved of the four oaks compared.
Jason Price caught two roof rats in one snap trap. 7 November 2018. These rats really liked the bait. This is a rare occurrence, as I could not find a similar image online.
