RFI – California Bats / Small Mammals
I am planning a trip to California most of the large mammal info is on Mammalwatching.
I am after contacts for small mammal trapping and bat emergence, roosts etc.
General route San Francisco to LA, to Death valley, Yosemite to approx Redding, and back to SF.
Any info appreciated
You look for droppings underneath, and wait for them to emerge. Usually canyon bats emerge first, then the yellow bats. Sometimes you see them crawling out, but sometimes they just drop down and take flight.

There’s a Yuma myotis roost in a bat house at Clear Lake State Park office, a colony of Mexican freetails under one of the highway bridges along the northern access road to Yosemite, and some Townsend’s big-eared bats in the boulder cave in Pinnacles NM. Check out the abandoned mines in and around Death Valley – they have fringed myotis and other bats sometimes. Red Rock Canyon near Salton Sea has lots of bats, including spotted bats. Canyon and Western yellow bats roost in palms in canyons near the southern entrance to Joshua Tree.
For rodents, Carrizo Plain is an absolute must. Check the tide chart for Palo Alto Wetlands – you can sometimes see saltmarsh harvest mice and ornate shrews during very high tides. Muir Woods have fog shrews (rarely seen) and jumping mice. Mono Lake area has all sagebrush species, plus a few surprises such as mountain beavers.
