Eagle Hill Masthead

Online Seminars ... Calendar

Eagle Hill natural history training programs have the following three formats.

Summer Week-long Seminars ... These are the traditional week-long, in-person, and in-residence field seminars we have been offering since 1987.

Fall Weekend Workshops... Our in-person and in-residence workshops offer shorter intensive learning opportunites over weekends with expert instructors. We have been offering them since 2014.

Online Seminars ... This page features our fully interactive Online Seminars. They are being offered througout the year as a direct result of and as a creative response to the coronavirus. They are intensive training opportunities with expert instructors who teach by way of a Zoom link. The are interactive without the use of recorded presentations. They have broad geographic applicability. Each includes suggestions for readings and references as well as helpful websites to efficiently augment what is covered during online presentations. The sharing of photographs is encouraged. Almost all are taught outside of normal work-week hour, i.e., during evenings (Eastern Time) and on weekends. A free Zoom account is needed. Classes are recorded so partipants can review them or make up missed ones. Recording are only available to participants.

Online Seminars Paired with a Study Group ... Some online seminars focus on taxa that are species-rich in the vicinity of Eagle Hill. These seminars pair well with informal self-study or group-study at Eagle Hill. Participants who choose to come to Eagle Hill for a nature retreat can spend the daytime collecting and studying specimens that are the focus of their online seminar, with the goal of preparing to participate in their online classes in the evening. They will join other participants from other locations. Seminar descriptions clearly state if a self- or group-study option is a good idea.

Nature Retreats ... Opportunities for nature retreats overlap with the above programs.

Online seminar participants are welcome for nature retreats at Eagle Hill.

They can participate in evening classes, explore the coast of Maine during the day, use microscopes, high speed internet, and a 10,000 volume library.
