I am a retired ecologist living in Austin, Texas. I studied the impacts of urbanization on birdlife for my graduate work (Ph.D., Univ. of Texas, 1987), and worked in the private and public sectors in the environmental field for the past 40+ years. My last gig was as the Wildlife Biologist at Balcones Canyonlands NWR here in Central Texas. I am interested in all things under the sun (and moon), but particularly energy flow in ecosystems, as well as the biogeography of birds and leps with an emphasis on endangered species.
