Thomas Jefferson: Birder in Chief


Program Description:



Thomas Jefferson published a tally of 125 bird species in his Notes on the State of Virginia (1784), now considered to be the first American bird “checklist.” A trove of unpublished documents from Jefferson’s preparation of this work shed new light on the extent of his ornithological knowledge and astute observation skills. Matthew Halley will lead us through the timeline of Jefferson's career, with a special focus on his contributions to ornithology, his love of mockingbirds, and interactions with early American ornithologists including William Bartram and Alexander Wilson. .
