Walter D. Koenig, Visiting Fellow, Cornell Lab of Ornithology and Graduate School Professor, Department of Neurobiology and Behavior, Cornell University; and Research Zoologist Emeritus, University of California, Berkeley

A Graduate School Professor in the Field of

Neurobiology and Behavior

My particular interests are in animal social behavior and in the behavioral ecology of oaks. If you're a potential Ph.D student, I am in the graduate field of Neurobiology and Behavior; however, be advised that I have retired from teaching and am no longer recruiting graduate students. See my "prospective graduate students" page for more details.

A brief presonal history

I came to Cornell in summer 2008 after many years as a Research Zoologist at UC Berkeley. For most of this time, I lived and worked at Hastings Natural History Reservation in upper Carmel Valley, California, where I still conduct long term research on the social behavior and ecology of acorn woodpeckers and patterns of acorn production in California oaks, and have returned as of late June 2016. In the past, I have also studied the population ecology of tiger salamanders and dragonflies and had students who have studied yellow-billed magpies, phainopeplas, wild turkeys, and African mongooses. At Cornell I taught Advanced Behavioral Ecology (BIONB4340) and in the introduction to Animal Behavior course (BIONB 2210), as well as a graduate seminar (Topics in Behavioral Ecology) in conjunction with Dr. Janis Dickinson. I'm now retired, but still active running the California Acorn Survey and involved, at least peripherally, in the Acorn Woodpecker project.

Dale & Phoebe

Phoebe and Dale Koenig studying birds at Hastings Reservation in 1994. Dale completed his Ph.D. in Geometric Topology at UC Davis in 2017. He then moved to Japan for a postdoc at the Okinawa Institute for Science and Technology and is now working for a startup in Tokyo. Phoebe graduated from Cornell where she is currently working on an MS in Entomology. Neither has changed a bit.
