Site description The Quill is the highest point on St. Eustatius (601 m) and forms the southeast part of the island. There is no human settlement above 250 meters elevation, which is designated as the Quill National Park. The park includes the vegetated caldera within this volcanic mountain. Goats are sometimes found grazing in the area, despite regulations against such activity.
Key Biodiversity Limited-range species which occur at the Quill include Bridled Quail Dove Geotrygon mystacea, Purple-throated Carib Eulampis jugularis, Green-throated Carib Eulampis holosericeus, Antillean Crested Hummingbird Orthorhyncus cristatus, BrownTrembler Cinclocerthia ruficauda pavida, Scaly-breasted Thrasher Margarops fuscus, Pearly-eyed Thrasher Margarops fuscatus, and Lesser Atillean Bullfinch Loxigilla noctis. One Scaly-breasted Thrasher was observed at the Quill in 2003, the last recorded sighting being in 1927. Breeding needs to be confirmed for this species. There is little data on migrant birds which use the Quill, but it would not be expected to be a significant overwintering or stopover area due to its small area.
Non-bird biodiversity: The restricted-range species Antillean Iguana Iguana delicatissima and Red-bellied Racer Alsophis rufiventris and the endemic Statia Morning Glory Ipomoea sphenophylla are present within the Quill Park
