    Hoary bat, Lasiurus cinereus

    • Don Roberson 6 years ago

      Hi Mark — I live in Monterey County and thought that this immediately looked like Big Brown Bat (Eptesicus fuscus), based on size/shape, and an apparent large head with largeish rounded ears, and by what I think I see as a very short stub of a ‘free’ tail (much shorter than freetailed bats but pretty much diagnostic, I think). I don’t see anything useful in the pelage; it looks all dark brown to me (not like Hoary Bat, in my opinion; further, Hoary Bat is rare here but Big Brown Bat is very common, and about the only bat you would likely see in January). Cheers, Don Roberson

    That is not a Big Brown. Those wing markings are typical of the genus Lasiurus in North America. You can see a picture of the wings of a Big Brown and Hoary Bat in the Kaufman mammal field guide.

    Thanks for all the help, it was a very hot day and warm evening perfect bat conditions.
