8 Types of Blackbirds in Delaware! (ID Guide)
What kinds of blackbirds can you find in Delaware?
Blackbirds are incredibly abundant in Delaware. But while they are common, some of these species get a bad reputation because of their aggressive personalities and tendency to “bully” smaller songbirds at bird feeders (cough… European Starlings… cough).
The term “blackbird” is a bit wide-ranging. For the sake of this article, I only included species in the Icteridae family (except for #2), which consists of all New World Blackbirds, grackles, cowbirds, and even orioles! I think you will find that the more you learn about the below birds, the more you can appreciate them and their natural behavior.
Below you will learn about 8 types of blackbirds in Delaware!
If you’re lucky, you may be able to see blackbirds at my bird feeding station right now! I have a LIVE high-definition camera watching my feeders 24/7. 🙂
For each species, I provide some fun facts along with how to identify them by sight OR sound. Make sure to pay attention to the range maps to see which blackbirds live near you!

The 8 Species of Blackbirds That Live in Delaware:
#1. Red-winged Blackbird
- Agelaius phoeniceus
- Males are all black, except for a bright red and yellow patch on their shoulders.
- Females are brown and heavily streaked. There is a bit of yellow around their bill.
- Both sexes have a conical bill and are commonly seen sitting on cattails or perched high in a tree overlooking their territory.

During the breeding season, these blackbirds are almost exclusively found in marshes and other wet areas. Females build nests in between dense grass-like vegetation, such as cattails, sedges, and bulrushes. Males aggressively defend the nest against intruders, and I have even been attacked by Red-winged Blackbirds while walking near the swamp in my backyard!

When it’s the nonbreeding season, Red-winged Blackbirds spend much of their time in grasslands, farm fields, and pastures looking for weedy seeds to eat. It’s common for them to be found in large flocks that feature various other blackbird species, such as grackles, cowbirds, and starlings.
It’s possible to see these blackbirds in Delaware at your feeders!

To attract them, try offering a combination of grains, such as millet and cracked corn, along with sunflower seeds.
Red-winged Blackbirds are easy to identify by their sounds!
Listen to their common songs and calls by pressing PLAY above!
If you visit a wetland or marsh in spring, you are almost guaranteed to hear males singing and displaying, trying to attract a mate. Listen for a rich, musical song, which lasts about one second and sounds like “conk-la-ree!”
And at any time of year, you can hear males or females make a “check” call. This sound is used for many purposes, such as when flying, feeding, or defending their territory.
#2. European Starling
- Sturnus vulgaris – This is the only species on this list that isn’t in the Icteridae family.
- A common blackbird in Delaware, they are about the size of an American Robin. Their plumage is black and appears to be shiny.
- Short tail with a long slender beak.
- Breeding adults are darker black and have a green-purple tint. In winter, starlings lose their glossiness, their beaks become darker, and they develop white spots over their bodies.
European Starlings are incredibly common in Delaware!

But, did you know these birds are an invasive species and aren’t even supposed to be here?
Back in 1890, one hundred starlings were brought over from Europe and released in New York City’s Central Park. The man responsible (Eugene Schieffelin) had a mission to introduce all of the birds mentioned in Shakespeare’s plays in North America.
The rest is history as starlings easily conquered the continent, along the way out-competing many of our beautiful native birds. Their ability to adapt to human development and eat almost anything is uncanny to almost no other species.
When starlings visit in small numbers, they are fun to watch and have beautiful plumage. Unfortunately, these aggressive birds can ruin a party quickly when they visit in massive flocks, chasing away all of the other birds while eating your expensive bird food. To keep these blackbirds away from your bird feeders, you will need to take extreme action and implement some proven strategies.
Starlings are impressive vocalists!

Listen for a mix of musical, squeaky, rasping notes. These blackbirds are also known to imitate other birds.
Here’s something amazing about European Starlings:
It’s the magical way they travel in flocks, called murmurations.

#3. Brown-headed Cowbird
- Molothrus after
- Look for a stocky, chunky blackbird with a thick, conical bill.
- Males have completely black bodies with a brown head (hence the name). In poor light, it can be hard to tell that the head is actually brown.
- Females are a plain brown color. There is slight streaking on the belly and a black eye.

Brown-headed Cowbirds are considered “brood parasites.”
Lastly, here is a question for you to ponder:
How does a Brown-headed Cowbird know it’s one? It’s interesting to think about since they aren’t raised by one of their own species. But after they leave the nest, they never spend time again with whatever type of bird their host mother was!
#4. Common Grackle
- Quiscalus quiscula
- Lanky, large blackbirds that have a long tail and long bill that curves slightly downward. Loud birds that gather in big flocks high in trees.
- Males are black overall but have an iridescent blue head and bronze body when seen in the right light.
- Females look similar, except they are slightly less glossy than males.

These large, aggressive birds can become a bit of a nuisance when they arrive in large flocks as they scare away smaller songbirds. Unfortunately, due to their athletic ability and willingness to eat most foods, they are one of the harder creatures to prevent at backyard feeding stations.
#5. Baltimore Oriole
- Icterus galbula
- Male birds are a stunning combination of orange and black with white wing bars.
- Females are beautiful in their own way, featuring duller colors than the males while lacking a black hood and back.
When you think about blackbirds in Delaware, you probably don’t think about Baltimore Orioles! But it’s true, as these stunning birds are members of the Icteridae family.
Baltimore Oriole Range Map
These blackbirds spend most of their time at the tops of deciduous trees, fluttering around, building beautiful woven nests, and looking for food.
They are most often found in open woodlands, riverbanks, and on the edges of swamps and forests. Even though they enjoy trees, they normally aren’t seen in deep, dark forests.
Baltimore Orioles LOVE eating ripe fruit and nectar!

These two sugary foods provide lots of energy, while insects give them the nutrition they need. Luckily, these birds are relatively easy to attract to your bird feeders, as long as you use the foods they enjoy eating.
Press PLAY above to hear a Baltimore Oriole singing!
Baltimore Orioles are often heard before being seen since they live so high up in trees. Listen for males to make a flutelike whistling noise while defending their breeding territory. Females also sing, but it’s shorter and used to communicate with their mates.
#6. Orchard Oriole
- Icterus spurius
- Male Orchard Orioles are a darker orange than Baltimore Orioles. Their plumage is best described as rust-colored.
- Females are greenish-yellow, with white wing bars on black wings.
These vibrant blackbirds are common in Delaware during summer.

But these shy birds are not often seen because they spend most of their time at the tops of trees. Preferred habitat includes the edges of rivers, swamps, lakeshores, open woodlands, farms, and scrublands. In winter, they migrate south to Central and South America.
While many oriole species regularly visit bird feeders, Orchard Orioles are much harder to attract to them.
You are probably more likely to see these blackbirds in your backyard searching for insects in shrubby vegetation or eating mulberries from a tree. But if you’re lucky, you may see them at your feeders eating sunflower seeds or orange slices, drinking sugar water from a nectar feeder, or sipping a bit of grape jelly.

An Orchard Oriole’s song is similar to an American Robin, except it’s more varied. Listen for a series of loud whistles that lasts 3-4 seconds, which is used to attract mates.
#7. Rusty Blackbird
- Euphagus carolinus
- Medium-sized blackbirds with slightly curved, slender bills.
- Breeding males are entirely glossy black. Non-breeding males are a duller black but with rusty-brown edging on their plumage.
- Females appear rusty colored or brown. Look for a pale eyebrow that contrasts against the black feathers around their eye.
Rusty Blackbirds pose a concerning mystery to scientists.
In Delaware, they have declined dramatically over the past 40 years, and no one knows why!
Rusty Blackbird Range Map
The problem with studying these blackbirds is that they breed in Canada’s far northern boreal forests, where not many people are around to observe their behavior.
Their preferred habitats are wet forests, marshes, pond edges, and swamps. Many of these areas have been drained and converted to agricultural uses, which may play a part in the loss of Rusty Blackbirds.
It’s also thought that the severe hunting of beavers over the past century has eliminated many smaller ponds, which is also another natural home used by these blackbirds.
If you are lucky enough to be around a Rusty Blackbird, listen for a creaky song (“koo-a-lee-eek“) that is a few notes long.
#8. Boat-tailed Grackle
- Quiscalus major
- These grackles are lanky looking and have long legs with a large, pointed bill.
- As the name suggests, adults have a long, V-shaped tail, which resembles the keel of a boat.
- Males are glossy black all over. Females look completely different, as they are smaller with a pale brown breast and dark brown upperparts.
When they are in the vicinity, it’s easy to identify and see these loud blackbirds in Delaware! Naturally, look for them in coastal salt marshes. But the easiest place to see them is around people as Boat-tailed Grackles are not shy!
Boat-tailed Grackle Range Map
They readily take advantage of humans for food and protection from predators. For example, when our family visits Disney World, I see them in large numbers, hanging out around busy food areas looking to scavenge leftover popcorn, pretzels, and french fries.
Boat-tailed Grackles have a unique mating system called “harem defense polygamy,” which is similar to how deer and elk breed. Female birds all cluster their nests close together and then let males compete (through displays and fighting) to see who gets to mate with the entire colony.
To identify them by their song, listen for a loud, abrasive “jeeb, jeeb, jeeb.“ Other noises include a variety of harsh rattles, clicks, screams, and whistles.
Great-tailed Grackles and Boat-tailed grackles were once considered the same birds until genetic analyses differentiated them as separate species.
