Comprehensive Database of Delaware Bird Sightings from Multiple Sources
Gene Hess created a database of bird sightings to use when he was writing the Birds of Delaware (Hess et al, Univ. of Pittsburg Press, 2000) and he has kept the database continuously updated. It contains almost 300,000 records of 468 species, 8 subspecies, and 4 species pairs dating back as far as 1794.
He is now making this database available for you to search. If you are doing research or are just curious about bird sightings in Delaware, submit your query below and Gene will respond with the results.
This database combines data from multiple sources and contains sightings not available anywhere else including older sightings not well represented on sources like eBird. See the list of sources below.
