I do not teach any courses at Cornell University as part of my work. From time to time I taught, or helped to teach short courses or workshops on different topics.
On 15 August 2016, I was co-teaching a workshop on the use of eBird data at the North American Ornithological Congress. Information and materials for this workshop are available here. Note that the contents of these pages have not been updated or otherwise altered since the date of the workshop. However, there is still useful information on these pages, including a link from which you can download the course materials (sample data, sample scripts to process the data, PowerPoint presentations).
