Benjamin E. Leese
Microbiologist by trade.
Ornithologist by passion.
I run a microbiology lab in a paper mill to test specialized filtration media for water purifcation. When I am not doing that, I am probably in my garden, at a baseball game, or trying to track down historical records of extinct birds.
Research Interests
My most recent manuscript describes more than 100 previously unreported records of the the Carolina Parakeet.
I have also written a series of manuscripts outlining historical records of the Ivory-billed Woodpecker north of its assumed southern range. I have uncovered records in Virginia, Kentucky, Indiana, and Ohio. The species appears on the list for Indiana because of my research.
I also updataed the list of specimens of the Imperial Woodpecker, alongside a variety of wonderful colleagues. I'm using those records to examine the species' unusual (for woodpeckers) habit of living in groups.
