About HAWAII AUDUBON SOCIETY

Hawai‘i Audubon Society is a Honolulu-based, member-driven birding and bird-conservation nonprofit founded in 1939 that operates statewide. It sponsors community science projects, leads habitat restoration teams and field trips, publishes the bimonthly peer-reviewed journal ʻElepaio, and produces educational resources including the Hawaiʻi’s Birds field guide. The Society manages and supports island-specific conservation efforts (including stewardship of seabird habitat) and runs recurring citizen-science programs such as the Kōlea Count; it also organizes public events and volunteer opportunities (for example, Kōlea Quest events listed for 2026). The organization maintains a public nonprofit presence with regular journal issues and outreach, ongoing habitat and seabird stewardship work, and active membership and volunteer programs across the state.
