Why Do Hawks Screech? The Surprising Truth

Hawks screech for a variety of reasons. They often do so to defend their territory from other hawks or intruders, and it can also be a means of communication with mates during the breeding season.

Additionally, hawks screech to warn their young of potential dangers or to express distress when they are injured or trapped. In some cases, they may also screech in response to being mobbed by smaller birds.

These vocalizations play crucial roles in hawk survival, reproduction, and social interactions. While some hawk species are quieter, most use screeches as an important part of their daily lives and behaviors.

Why Do Hawks Screech?

Hawks are amazing birds that catch our eye with their graceful flight and sharp eyes. But it’s their loud, piercing screech that often grabs our attention first. Why do these powerful birds make such noisy calls? 

Let’s dive into the world of hawk vocalizations and uncover the surprising reasons behind their screeches.

1.Territory Calls:

One of the main reasons hawks screech is to protect their territory. A territory is an area a hawk claims as its own for hunting, nesting, and raising young. When a hawk screeches in its territory, it’s usually saying:

• “This is my space!” “
• Stay away, other hawks!” 
• “I’m strong and ready to defend my area!”

Hawks are very serious about their territories.

A study in the Journal of Raptor Research found that Red-tailed Hawks can have territories as large as 690 acres (that’s about 522 football fields)!

Here’s how territory defense usually works:

• A hawk spots another hawk or potential threat
• It flies to a high perch in its territory
• The hawk lets out a loud screech
• It may fly around the area, screeching more
• If the intruder doesn’t leave, the hawk might attack

This behavior is especially common during breeding season when hawks are extra protective of their nesting sites.

2.Hawk’s Communication:

Hawks don’t just screech to scare others away. They also use calls to talk to each other, especially during mating season. Here are some ways hawks use their voices to communicate:

Finding a Mate

During breeding season, hawks use special calls to attract partners. These calls might sound gentler than their usual screeches. 

For example:

• Male Red-tailed Hawks make a “chirp” sound to call females
• Cooper’s Hawks use a “kik-kik-kik” call during courtship

Keeping the Family Together

Once hawks have babies (called nestlings), they use different calls:

• Food calls: Parents make special sounds when bringing food to the nest
• Begging calls: Baby hawks make high-pitched sounds when they’re hungry
• Warning calls: Parents screech to warn their babies about danger

A study in The Auk (a bird science journal) found that Ferruginous Hawk parents made different calls based on the threat level to their nest. The more dangerous the threat, the more intense the calls!

3.Hawk’s Distress Calls:

Sometimes, a hawk’s screech is a cry for help. Distress calls are different from normal screeches. They’re often:

• Louder
• More frequent
• Higher-pitched

Hawks might make distress calls when:

• They’re caught by a predator
• They’re injured
• They’re trapped or tangled in something

Other animals, including other hawks, often respond to these calls. They might come to help or to see what’s happening.

“Distress calls in birds are a universal language of danger,” says Dr. Ellen Ketterson, an ornithologist at Indiana University. “They can alert other species, not just their own kind, to potential threats.”

4.Hawk’s Screech When Mobbed :

Hawks aren’t always the top predator in the sky. Sometimes, smaller birds gang up on hawks in a behavior called “mobbing.” When this happens, hawks often screech loudly. Here’s what mobbing looks like:

• A group of small birds (like crows or jays) spot a hawk
• They fly around the hawk, diving at it and making loud noises
• The hawk screeches and tries to fly away
• The smaller birds chase the hawk out of their area

Hawks screech during mobbing to:

• Scare off the attackers
• Call for help from other hawks
• Express their frustration

Why do smaller birds do this? They’re trying to:

• Protect their nests and young
• Drive the hawk away from their territory
• Warn other birds about the predator

A study in the journal Behaviour found that mobbing can be very stressful for hawks and may even make them avoid certain areas.

Why a Hawk Might Screech All Day

Sometimes, people notice a hawk screeching for hours or even all day. It means that there could be something wrong with them. And another scenario could be that the young hawks (nestlings) are calling, and the parents are responding to their young.

Here are some reasons a hawk might screech non-stop:

1. Stuck or injured: The hawk might be trapped or hurt and calling for help
2. Very hungry: A starving hawk might call out constantly
3. Lost baby: Parent hawks may screech for a long time if they can’t find their young
4. Inexperienced juvenile: Young hawks learning to hunt might get frustrated and noisy
5. Extreme stress: Something in the environment (like construction) might be really upsetting the hawk

Hawk screeching can be startling:

Nestling communication: 

Young hawks are quite vocal, constantly calling to their parents for food and attention. This “feeding frenzy” can result in frequent screeching throughout the day.

Parental responses: 

Adult hawks respond to their nestlings with their own calls, creating a back-and-forth “conversation” that can seem endless to human ears.

Sibling rivalry:

 In nests with multiple chicks, competitive screeching for food and attention is common, adding to the overall noise.

Hunting lessons: 

As nestlings grow, parents may use vocalizations to teach hunting techniques, adding an educational component to the screeching.

Fledgling period: 

When young hawks start to leave the nest, their screeching often intensifies. They may call out in excitement, fear, or frustration as they learn to navigate their new world.

Mating rituals: 

Even with nestlings present, hawks may engage in mating calls to strengthen their pair bond, contributing to the day-long chorus.

Hawks That Don’t Screech Much : 

Not all hawks are noisy. Some species are known for being pretty quiet most of the time. These include:

• Northern Goshawk: This forest hawk is usually silent except during mating season
• Broad-winged Hawk: They have a high-pitched whistle but use it sparingly
• Rough-legged Hawk: These Arctic hawks are generally quiet

Why are some hawks quieter? It often has to do with their hunting style:

• Quiet hawks can sneak up on prey more easily
• They might live in areas where sound doesn’t travel well
• Some hawks hunt by watching from a perch, so they don’t need to call as much

Even these quiet hawks will screech if they need to defend their territory or are in distress.

Do Hawks Really Screech After Dark?

You might hear screeching at night and wonder if it’s a hawk. But here’s a surprise: most hawks are quiet at night! They’re usually screech in daytime, which means they’re active during the day and sleep at night.

So what’s making those night noises?

Here are some common nocturnal birds that people often mistake for hawks:

Owls:

Owls are night-active birds of prey. Their calls can sound a lot like hawk screeches. Some common owl calls:

• Great Horned Owl: A deep “hoo-hoo-hoo”
• Barn Owl: A loud, raspy shriek
• Screech Owl: A trilling whistle or whinny

Nightjars:

These are birds that catch insects at night. They make some weird sounds:

• Common Nighthawk: A nasal “peent” call
• Whip-poor-will: A repeating “whip-poor-will” whistle

Herons:

These long-legged water birds can make loud squawks at night:

• Great Blue Heron: A harsh “frhank” sound
• Black-crowned Night Heron: A loud “quock”

If you’re hearing screeches at night, it’s probably one of these birds, not a hawk.

What Does hawk’s screech Sound Like?

If you’ve ever heard a hawk screech, you know it’s hard to forget. But how would you describe it? 

Here are some ways people often explain the sound:

• A loud, high-pitched “kee-eeeee-arr“
• A sharp, piercing cry
• A screaming whistle
• A raspy shriek

Different hawks make different sounds. For example:

• Red-tailed Hawks have a hoarse, screaming “kee-eeeee-arr” that lasts 2-3 seconds
• Cooper’s Hawks make a repeated “cak-cak-cak” sound
• Sharp-shinned Hawks have a high-pitched “kik-kik-kik” call

Fact : Hawks make these sounds using a special organ called the syrinx. It’s like our voice box, but for birds. The syrinx is at the bottom of their windpipe, where it splits into two tubes going to the lungs. This lets hawks (and other birds) make complex sounds and even two different notes at once!

What to Do About the Noise When Living with Hawks:

Hawks are protected by law in many countries, including the United States. This means we need to learn to live with them, even if they’re noisy. 

Here are some tips:

1. Understand the reasons: Remember, hawks screech for important reasons like defending territory or communicating with family.
2. Enjoy the wildlife: Try to appreciate having these amazing birds nearby. Watch them soar and hunt – it’s nature in action!
3. Protect your pets: Keep small pets indoors or supervised outdoors. Hawks might see them as prey.
4. Don’t feed hawks: This can make them too comfortable around humans and lead to conflicts.
5. Call experts: If a hawk seems to be in trouble or is causing serious issues, contact local wildlife authorities for help.

“Learning to coexist with wildlife, including hawks, enriches our lives and helps maintain healthy ecosystems,” says John Marzluff, Professor of Wildlife Science at the University of Washington.

Conclusion: 

Hawk screeches aren’t just random noise. They’re complex communications that play important roles in hawk life. Hawks’ screeches are more than just noise, they are a vital part of these birds’ lives.

Understanding these calls helps us appreciate hawks more and live better alongside them. Next time you hear a hawk screech, you’ll know there’s a lot more to that sound than meets the ear!
