50 Birds Of Delaware
The heart of the Mid-Atlantic region of the United States is a state rich in natural beauty and biodiversity. From its pristine coastal habitats to its lush inland forests, Delaware provides a haven for many bird species.
Here are 50 Birds Of Delaware.
1. American Robin
The American robin is a migratory bird belonging to the valid thrush genus and Turdidae family.
It was named after its European counterpart due to the similar reddish-orange breast they possess; however, they are not closely related.
This species can be seen through most of North America during winter months and in parts of Mexico and Central America, where it also breeds.
They have plump bodies with gray upperparts and white underparts that vary from yellow on their throats down to orange toward their bellies.
Robins feed on fruits such as berries or insects like worms, making them an essential part of ecosystems by helping disperse seeds naturally throughout these areas.

It’s also known as an “American Rosefinch” due to its resemblance in color and size to some European rosefinches.
Their plumage ranges from pinkish-purple on their heads and wings with a light brown underside.
Small birds measure about 5-6 inches long with short, thin beaks for eating seeds and insects.
In addition, they have thick, round bodies, which help them stay warm during cold winters in the northern parts of their range.
The Purple Finch has adapted well over time, making it easier for them to survive despite increasing threats posed by humans, such as deforestation or habitat destruction caused by development projects near their habitats.

It has an extensive range, from the Pacific and Atlantic coasts of the US to Canada and Central America, with a concentration in northern areas during the breeding season.
These birds migrate southwards for wintering grounds, where they find plentiful food sources such as insects and berries.
They are easily identified by their yellow patches on either side of their tails, white underparts, gray back feathers, and two distinct crown stripes.
One black or greyish-brown above the eyes extends towards its neck and is banded in yellow or light brown.
Furthermore, these singers have strong legs, which allow them to cling to branches while hunting for prey, making them adept at maneuvering through tree cover quickly.
Altogether, this makes the Yellow-rumped Warbler an attractive backyard visitor year-round.

This species belongs to the Buteo genus, making it one of Earth’s most common raptorsarth.
These hawks mainly hunt small mammals such as rabbits or squirrels but also feed on reptiles and birds during migration season.
Unlike other predator birds, they prefer open areas for hunting, like fields or grasslands, rather than dense forests.

The birds are grey above with white underparts, have a rufous cap with black stripes, and large eyes surrounded by light brown feathers.
They feed mainly on seeds but can also be seen eating insects during breeding season when raising their young chicks.
These brave little birds live in open grasslands such as prairies or meadows, building cup-shaped nests in trees or shrubs to raise their young family.

For many years, it was considered part of the same species as the Striated Heron (Butorides striata), commonly referred to as “green-backed herons.”
The nominate subspecies inhabits wetlands across much of this range, where they can be spotted stalking about in shallow water, looking for fish or frogs on which to feed.
They are fascinating wading birds that have even been known to use tools such as sticks or baited lines when fishing.

It has black upperparts contrasted by long white wings with a glossy sheen. Its striking red eyes are set against its white facial mask, while its legs are bright pinkish.
The Haematopus mexicanus species inhabits marshy wetlands and brackish lagoons where it feeds on insects, crustaceans, small amphibians, and fish, which they catch using their slender bill or chase after them as they run across the surface of water or mudflats.
This bird typically nests near shallow waters but will use any habitat type if food resources are available nearby. It is a highly adaptable species for human-altered habitats such as rice fields and sewage ponds.

It was described by German naturalist Johann Friedrich Gmelin in 1789 and placed into the genus Scolopax.
This species has buff upperparts, white underparts, yellow legs and feet, olive green wings with white edges on its secondaries and tertials, and a thin black bill that curves downward towards its tip.
The male lesser yellowlegs are slightly larger than females and can be distinguished from other waders due to their unique call; they will often make loud “chew” or “churr” noises when alarmed during the breeding season.
They typically feed on small aquatic insects such as beetles, flies, moths, etc., but may also eat crustaceans such as shrimp or water snails if available.

46. Great Skua
The Great Skua is a large sea bird belonging to the family Stercorariidae, found in areas such as the Faroe Islands and Iceland.
It has a size similar to that of herring gulls, with its diet consisting mainly of fish caught at the surface or taken from other birds.
This species was first described by Danish zoologist Morten Thrane Brünnich in 1764 under the name Cath.
They are potent predators who sometimes use mobbing tactics against larger prey like gannets and eiders until they give up their catch.
These birds mate for life but may build nests near colonies if there aren’t enough suitable territories on their island range.
Although these skuas might seem intimidating due to their fierce nature when protecting young, they can be pretty timid around humans, so they should not be approached too closely.

47. Greater Yellowlegs
The Greater Yellowlegs is a large shorebird found in the family Scolopacidae. It nests mainly in central Canada and south Alaska while wintering in southern North America, Central America, West Indies, and South America.
German naturalist Johann Friedrich Gmelin formally described the bird as part of his revision to Carl Linnaeus’s Systema Naturae.
It has long yellow legs, which sets it apart from other birds; when disturbed or alarmed, they will flash these bright-colored limbs about wildly.
Its diet consists mainly of insects like flies, beetles, grasshoppers, and dragonflies, although aquatic invertebrates are occasionally eaten.
These birds have adapted well to human habitation near shallow marshes or mudflats with plenty of food sources to feed upon, making them an easier species for people who love bird watching.

The Red Knot is a medium-sized shorebird that inhabits tundra and Arctic Cordillera in the far north of Canada, Europe, and Russia.
It belongs to the Calidris sandpipers family, one of its most prominent members, second only to the Great Knot.
This species has six subspecies recognized worldwide. During the breeding season, their diet consists mainly of arthropods and larvae; however, they may also feed on other items, such as mollusks or crustaceans, according to availability during migration periods.
They are known for their long migratory journeys, which can last up to 20,000 kilometers per year – from wintering grounds in South America through North American coasts until reaching summer nesting sites across Northern Eurasia.

50. Sharp-Shinned Hawk
The Sharp-shinned Hawk is a small hawk found throughout the United States and Canada. It is one of the smallest hawks in North America but more significant than some Neotropical species, such as the tiny hawks.
The taxonomy of this bird remains uncertain, with some authorities suggesting that southern taxa may represent three distinct species: white-breasted Hawk (A. chionogaster), plain-breasted hawk (A. ventralis), and rufous morph sharp-shinned hawk (A. rufiventris).
These birds feed primarily on small birds like finches, sparrows, woodpeckers, and warblers while hunting from perches or flying through dense vegetation to surprise unsuspecting prey.
They are agile flyers that rely heavily on surprise to capture food items before they can fly away quickly.
