1. Bat tattoo from Uzi (@waachip) at American Graffiti Tattoo (@americangraffititattoo). I’m thrilled: I’ve wanted a bat tattoo for years, and @ranewc made it happen for our anniversary.

  2. Metamorphosis — common green darner (Anax junius) adult emerging from its nymph (juvenile) exuvia. The white stringy stuff is tracheal lining.

  3. Great-horned owl (Bubo virginianus) … inadvertently caught and released whilst mist- netting.

  4. A juvenile male western red bat (Lasiurus blossevillii).

  5. Hoary bat (Lasiurus cinereus). A beautiful young mother we radio- tagged.

  6. At play in Belize with a great fruit-eating bat (Artibeus lituratus).

  7. Leaf-cutter ant at work.

  8. Spiny tailed iguana on Mayan ruins.

  9. This was my office on Tuesday night for bat roost surveys. So much better than the gilded-cage of my former law practice! #wildlife-biology-porn

  10. Calochortus tiburonensis. Designated as threatened on both the California and federal endangered species acts. Grows only on one hillside above Corte Madera. Ugly and beautiful.
