California Bat Removal
The California Bat Conservation Fund is a non-profit California organization dedicated to the preservation of California bats. The California fund's major activities include:
• dispelling widespread misconceptions about California bats through informative presentations and live-bat displays at schools, libraries, museums, and community centers
• restoring injured and orphaned California bats to health and returning them to the wild
• working alongside major California conservation efforts to replenish shrinking bat populations
California silver haired bat has fur that is uniformly black, and many of the bat hairs are distinctly silver-tipped, especially on dorsal (back) surface
California bats have a tail extending conspicuously (more than 30 mm) beyond edge of interfemoral membrane, a California membrane stretching between tail and hind legs.
California bats have no extension of tail beyond edge of interfemora membrane.
California bats have a forearm more than 70 mm
California bats have ears more than 20 mm in height from notch to crown
California bats have ears widely separated; hair yellow next to skin, forearm (radius) more than 46 mm
California bats have ears close together at anterior base while hair plumbeous (blackish gray) is next to their skin.
California bats have forearms more than 45 mm with silver-tips on some hairs and are sometimes known as the Hoary Bat.
California bats first visible tooth is behind the upper canine about 1/2 as high as the canine and in contact with it at the base.
The best way to introduce the California bats is probably by showing you a picture or two for each and then giving you a bit of information on the California natural history of the bats. I will present the bats in California alphabetical order, using their scientific names. The California photos are mostly from a California great book ("Bats of America" by Roger Barbour and W. H. Davis. 1969 Univ. of Kentucky Press). This California book has a good key to the bats of North America. A significant key to California bats will allow you to figure out which California bat you have in your hand. California photos should not be used elsewhere without permission. Amy Fesnock of Pinnacles National Monument straddling San Benito and Monterey Counties, made the bat voice recordings. Bat vocalizations are recorded with special microphones that can hear sounds that are 10x higher in frequency than humans can hear. To let us hear the sounds, they were translated by dividing the frequency by 10; thus a 20,000 Hz sound is beyond most of our hearing and is presented here as 2,000 Hz. Jeff Froke, Santa Lucia Preserve, on the southwestern flanks of Carmel Valley provided information on bat distribution there. Other information is derived from the files at Hastings.
