Diana Humple

Senior Avian Ecologist & Banding Coordinator

I am a Senior Avian Ecologist with Point Blue Conservation Science’s Pacific Coast and Central Valley Group. I serve as program lead for the Palomarin Field Station, where I coordinate the science, training, and outreach that our team of staff and interns conducts at our organization’s longest-running study site (née 1966) and keystone dataset. My other primary roles include: managing various landbird monitoring projects throughout the Bay Area; banding and permit coordinator; and coordinator of Point Blue’s oil spill response and preparedness efforts for the state of California and the Oiled Wildlife Care Network. Thankfully I still get out into the field with intermittent regularity.

I received an undergraduate degree in environmental science (ecology) and psychology from the University of Virginia in 1995, and subsequently came to Point Blue as an intern in 1996 studying birds in the shrubsteppe of Oregon and banding at Palomarin. In 2009 I completed a Master’s Degree in Biology at Sonoma State University studying genetics and oil spill demographics of Western and Clark’s Grebes. My primary interests include: intern training and public outreach to instill an appreciation of birds, natural history, and conservation science; bird banding and monitoring techniques; migratory ecology; phenology (the study of seasonal cycles); oil spill science, preparedness, and response; and long-term monitoring of landbird populations to identify trends and the mechanisms and consequences of change.

I am fortunate to be based out of the Palomarin Field Station in the south end of Point Reyes National Seashore.
