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 provides activities and field trips for school age birders and their families.  

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 2800 acres of critical bird habitat.
