What we do

We run field trips throughout  the year to Delaware's birding hotspots.

We hold monthly meetings with wide ranging topics from professional presenters.  

We work to conserve critical bird habitats in partnership with other organizations and the state.  

Our youth birding group and co-sponsorship of the Frontiers in Ornithology Symposium provide activities for school age birders.  

From Hawk Watches to Christmas Bird Counts, we run a number of projects studying Delaware's birds.

Our signature fundraising event has raised money to purchase over 2000 acres of critical bird habitat.
