4 Types of Corvids Found in Delaware (Crows, jays)
What kinds of corvids can you find in Delaware?
Corvids, which include crows and jays, are a family of birds known to be some of the SMARTEST birds that have ever been studied. For example, certain corvid species have demonstrated self-awareness in mirror tests and the ability to use tools while foraging for food. Both of these skills are INCREDIBLY rare in the wild kingdom.
And believe it or not, their brain-to-body mass ratio is about the same as great apes and whales and is only slightly lower than humans!
Today, you will learn about the types of corvids found in Delaware!
- If you’re interested, you may be able to see some of the species listed below at my bird-feeding station right now! I have a LIVE high-definition camera watching my feeders 24/7. 🙂
#1. American Crow
- Corvus brachyrhynchos
- A large bird that is entirely black with an iridescent sheen.
- Long black bill, black legs, and black feet.
American Crows are adaptable birds and are common in Delaware in almost every habitat. The places they can be found include woodlands, fields, rivers, marshes, farms, parks, landfills, golf courses, cemeteries, and neighborhoods.

While they don’t come to feeders as often as other birds, a few foods attract them consistently. The crows in my backyard LOVE peanuts, whether in the shell or out. Whole-kernel corn and suet also seem to be consumed readily.
These corvids are one of the smartest birds in Delaware.
For example, they can use tools, solve problems, and recognize human faces. It seems that crows even do things just for fun! Seriously, if you search the internet, it’s easy to find videos of them using round objects to sled down roofs.
American Crows have a large vocabulary. Listen for any number of caws, rattles, cackles, and clicks. The most common sound is a “caw-caw.” (Listen below)
#2. Blue Jay
- Cyanocitta cristata
- Backs are covered in beautiful blue feathers with black bars throughout. The underparts are white.
- Their head is surrounded by a black necklace and has a blue crest on top.
- Males and females look the same.
Some people dislike Blue Jays, but I love their bold personalities. Their high intelligence makes these corvids interesting to observe, not to mention their plumage is stunning.

Blue Jays typically visit bird feeders noisily, fitting as much food as possible in their throat sacks, then leaving quickly to eat or store their bounty. My favorite foods to use are whole peanuts, as Blue Jays are one of the only birds that can crack open the shells to access the inside! You can also use sunflower seeds and corn to attract them.
Jays are one of the noisier birds you will hear in Delaware.
The most common vocalization that I hear is their alarm call, which sounds like it’s saying “jeer.”
These corvids are also excellent mimics and frequently imitate hawks. They are so good it’s hard to tell the difference between which bird is present. It’s thought that jays do this to deceive other birds into believing a hawk is present. Not a bad plan if you want to get a bird feeder all to yourself!
#3. Common Raven
- Corvus corax
- Large bird that is completely black, including its eyes and bill.
- The bill is hefty and thick.
- In flight, look for their wedge-shaped tail.
Ravens are one of the SMARTEST birds in Delaware!
For example, one study has shown that these corvids are drawn to gunshots during hunting season to investigate the carcass but ignore other loud noises that don’t lead to food, such as air horns or car alarms.
Their intelligence makes them efficient predators, and it’s common for ravens to team up to get food, such as stealing eggs from nests or attacking larger prey like newly born lambs.

Since they are so smart and adaptable, Common Ravens are found in many habitats in Delaware. Look for them living near the edges of towns, especially in landfills that supply an endless amount of food. But ravens also have no problem living far away from civilization.
Common Ravens are impressive vocalists that make many different types of calls, from harsh grating calls to shrill alarm sounds. But the most common sound you will hear in the wild is a gurgling croak that rises in pitch.
Interestingly, they can mimic the sounds of many other bird species and even humans if raised in captivity.
#4. Fish Crow
- Corvus ossifragus
- Completely black, including legs, bill, and eyes.
- Slightly smaller than American Crow.
It can be hard to tell Fish Crows apart from American Crows in Delaware.
These two corvids look almost identical! And to make things even more confusing, these two species sometimes spend time together in mixed flocks. 🙂

But luckily, once you learn how to identify the calls that Fish Crows make, it can be easy to make a proper identification. Fish Crows make a short, nasally sound that sounds like someone is saying “cah” or “uh.” This noise is quite different from an American Crow’s “caw-caw.” LISTEN BELOW!
Like other corvids, Fish Crows are social, intelligent, and adapt well to life around people. The best places to find them are near bodies of water.
Despite their name, they eat almost anything they can find, including eggs, nestlings, fruit, grains, carrion, marine invertebrates, trash, and human food.
