I am a Scientist at the National Radio Astronomy Observatory. I have been stationed at NRAO's headquarters in Charlottesville, Virginia since 1972. This job put me in a lovely location for birding with mountains only 30-minutes away and the ocean only 3 hours down Interstate 64. It also required me to travel a good bit to Socorro, New Mexico and has now transferred me there on a permanent basis (see new house). My job has also required me to travel occasionally to Tucson, Arizona (see TAC for example). I was a member of the Charlottesville, VA Monticello Bird Club and am a member of the New Mexico Ornithological Society, the American Birding Association, and the Friends of the Bosque del Apache National Wildlife Refuge.

My main hobby is the photography of birds. I am not a patient, professional sort of photographer. Instead I used to haul along my Celestion C-90, 1000-mm focal length, f11 lens on a shoulder stock and shoot pictures when birds allow me the opportunity. On Central American and pelagic trips I have used a light-weight, hand-held 400mm lens instead. Nonetheless, I now have at least vaguely recognizable photos of over 2439 spieces of birds which is 71.6 per cent of my total world list.

I have scanned in my recent (year 2000 and later) photos into the computer and I attach a selection below. Click on the small picture to see a larger collection of small pictures. You may click on these small pictures to see the full, more detailed versions.

In October 2006, I acquired a digital camera (Canon 350D) with a 70-300 mm IS lens. For details and early, more personal pictures click here. Nature photographs with this camera appear for all photos from that time until July 2009. I have now purchased a more advanced camera (Canon T1i and now T3i) with a 100-400 mm IS lens. These promise 3.3 times as many pixels on the bird, the possibility of movies, and more. Watch for pictures from this outfit beginning with Namibia (September 2009).
