This list of birds of Delaware includes species credibly documented in the U.S. state of Delaware and accepted by the Delaware Bird Records Committee (DBRC). As of August 2021 there were 427 species on the official list. Of them, 100 are classed as accidental and six were introduced to North America. One species whose record is under review by the DBRC is not included.
Only birds that have occurred as wild individuals in Delaware are listed; this includes introduced species which have established self-sustaining populations in the wild. Birds thought to have occurred only as escapes from captivity are not included.
This list is presented in the taxonomic sequence of the Check-list of North and Middle American Birds, 7th edition through the 62nd Supplement, published by the American Ornithological Society (AOS). Common and scientific names are also those of the Check-list, except that the common names of families are from the Clements taxonomy because the AOS list does not include them.
The following tags have been used to annotate some species:
(A) Accidental - occur seldom and unpredictably and require documentation for reports to be accepted by the DBRC to enter the official record (I) Introduced - a species established by direct or indirect human intervention
Ducks, geese, and waterfowl Order: AnseriformesFamily: Anatidae
The family Anatidae includes the ducks and most duck-like waterfowl, such as geese and swans. These birds are adapted to an aquatic existence with webbed feet, bills which are flattened to a greater or lesser extent, and feathers that are excellent at shedding water due to special oils.

Chimney swift, Chaetura pelagica
Hummingbirds
Order: ApodiformesFamily: Trochilidae

Rails, gallinules, and coots
Order: GruiformesFamily: Rallidae
Rallidae is a large family of small to medium-sized birds which includes the rails, crakes, coots, and gallinules. The most typical family members occupy dense vegetation in damp environments near lakes, swamps, or rivers. In general they are shy and secretive birds, making them difficult to observe. Most species have strong legs and long toes which are well adapted to soft uneven surfaces. They tend to have short, rounded wings and to be weak fliers.

Most species eat small invertebrates picked out of the mud or soil. Different lengths of legs and bills enable multiple species to feed in the same habitat, particularly on the coast, without direct competition for food.
