I'm an experienced birder, beginner with odes, herps and butterflies, and a rank novice at just about everything else. I live in California and enjoy traveling to see nature in other parts of the world, especially Latin America. I have 3 kids who I enjoy spending time with in nature.

I create apps for nature enthusiasts and my projects include BirdsEye, eBird Mobile (with the Cornell Laboratory of Ornithology), Merlin (Cornell Lab), Dragonfly ID app (OdonataCentral / DSA), Bumblebee watch (Xerces Society), Milkweed/Monarch project (Xerces), the NARBA the North American Rare Bird Alert (Houston Audubon Society), the Birds of Peru field guide (Princeton University Press), Birds of New Guinea (Princeton), Birds of Ecuador (Cornell University Press), Birds of the Galapagos (Charles Darwin Foundation) and others.
