Summer Field Seminar Calendar

Summer Field Seminars. This page features our traditional week-long, in-person field seminars we have been offering since 1987. All are intensive training opportunities that are taught by expert instructors. All involve field trips that are focused on learning about the ecology of species in their natural outdoor environment. The indoor classroom part of these seminars includes lectures, discussions, and lab identifications and studies of specimens that have been collected in the field. They begin with a Sunday late afternoon arrival and dinner at 7 PM, followed by an introductory program. Mondays through Fridays are full teaching days, with meal times as relaxed settings for informal discussions. Evenings are set aside for discussions by the fireplace in the dining hall's comfortable lounge or for follow-up classroom activities. They conclude after breakfast on Saturday.

Other Eagle Hill Natural History Programs:

Fall Weekend Workshops. These 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. These fully interactive seminars are taught online by expert instructors outside of normal work-week hours, i.e., during evenings (Eastern Time) and on weekends. They are offered by way of Zoom and are interactive without the use of recorded presentations.

Nature Retreats. The Eagle Hill Institute is open for Nature Retreats year-round, for guests who would like to escape to the coast of eastern Maine to immerse themselves in nature.

Early Registration Discounts. Save on tuition costs by registering for seminars early—6% if you register at least 8 weeks before the start-date of a seminar, or 3% if at least 4 weeks before. To qualify, your registration must be accompanied by a deposit or purchase order. Early registration discounts apply only to tuition, but are calculated before, and cumulate with, other general discounts you qualify for.
