Grouped by each record’s archive date. Approximate dates keep their original labels in the records below.

  1. Acadia National Park Maine
    Unidentified https://www.inaturalist.org/observations/33101842

    Direct original iNaturalist page and photograph reviewed. A group of live harbor seals is hauled out on seaweed-covered rocks; overlapping bodies make exact count unreliable. Harbour seal

  2. Winter Harbor Maine
    Unidentified https://www.inaturalist.org/observations/61434712

    Direct original iNaturalist page and photographs reviewed. A large mixed haulout is visible on rocks. Source comments indicate both harbor and grey seals; exact count is unreliable because bodies overlap, and the page header is not applied to all animals.
