When we think of hawks, we often picture a solitary predator soaring high in the sky or perched silently in a tree, surveying its domain with laser-sharp focus. But did you know that hawks do sometimes gather in groups—and when they do, they go by some very interesting names?
So, what is a group of hawks called?
The most commonly used term is a “kettle” of hawks when they’re flying in circles during migration. But that’s not the only name. A group of hawks is also called a cast, a boil, or even a spiraling flock depending on the context.
In this article, we’ll break down the terminology, behavior, and symbolism behind hawk groupings. We’ll also answer popular questions about why and when hawks flock together and explore what these gatherings mean both biologically and culturally.
What Is a Group of Hawks Called?
The most well-known term for a group of hawks is a “kettle”—especially when they are seen soaring in thermals together during migration. However, other collective nouns for hawks include:
- A kettle of hawks (in flight)
- A cast of hawks (especially in falconry)
- A boil of hawks (less common, sometimes used when hawks are seen rising en masse)
- A flight or furnace of hawks (used in older or poetic texts)
So if you’re ever standing under a sky filled with circling raptors, you can impress your friends by saying, “Look! A kettle of hawks!”
Different Terms for Groups of Hawks
Let’s break down the different terms used to describe a group of hawks:
Kettle
The term kettle is the most accurate when referring to hawks flying in spirals on rising columns of warm air (thermals). It resembles the motion of boiling water, hence the name.
Cast
Cast is often used in the world of falconry, where a pair or trio of trained hawks are released together. The word reflects the strategic release and coordination of the birds.
Boil
Less common than “kettle,” the word boil may also describe a mass of birds erupting into the sky—creating a swirling, chaotic pattern.
Other poetic or literary terms
Some older texts refer to a furnace, flight, or leash of hawks. These terms are rarely used today but occasionally pop up in falconry or literature.
Why Do Hawks Form Groups?
You might be wondering: aren’t hawks solitary predators? Most of the time, yes. But there are important reasons why hawks may gather:
1. Migration
This is the primary reason hawks form large groups. During migration season, hawks use thermals to gain altitude with minimal effort. Multiple hawks may share the same thermal, creating a kettle.
2. Protection and Navigation
Flying in groups can offer mutual protection against predators like eagles. Younger hawks may also learn migratory routes by following older, more experienced birds.
3. Breeding and Roosting
While hawks are generally solitary during nesting, they may gather near ideal breeding habitats before dispersing. Some species roost communally outside the breeding season.
When Do You See a Kettle of Hawks?
Hawk kettles are most commonly observed during migration season, particularly:
- Fall (August to November)
As birds head south to avoid the cold - Spring (March to May)
When hawks return to breeding grounds
They’re often seen along ridge lines, coastlines, and thermals, where conditions are ideal for soaring.
Hawk Mountain in Pennsylvania and Corpus Christi in Texas are famous spots for witnessing massive kettles, sometimes numbering in the thousands.
What Is a Flock of Hawks Called in Flight?
When hawks are soaring together in the sky, the proper term is a kettle. But calling them a “flock of hawks” isn’t necessarily wrong—it’s just more generic.
Let’s compare:
| Term | Context | Description |
|---|---|---|
| Kettle | Migration | Hawks circling in thermals |
| Flock | General | Generic term for any bird group |
| Boil | Sudden Flight | Rapid, rising group |
| Cast | Falconry | Group of trained hawks released together |
So, next time you wonder what is a flock of hawks called, remember—if they’re circling, “kettle” is the best term!
Do Hawks Hunt in Groups?
Generally, hawks are solitary hunters. They rely on stealth, speed, and precision—skills best used alone. However, there are exceptions.
Cooperative Hunting
Some species, such as the Harris’s Hawk, have developed cooperative hunting behaviors. These hawks work in family groups, using teamwork to flush out prey or take turns chasing it down.
This makes Harris’s Hawks one of the few raptor species where seeing a group of hawks called a cast or pack during hunting is normal.
Hawk Species Most Likely to Form Groups
Not all hawks are equally social. Some are more likely to be seen in groups—especially during migration or hunting.
1. Broad-winged Hawk
- Most famous for huge kettles
- Thousands seen together in migration
- Spectacular to witness!
2. Swainson’s Hawk
- Migrates in large numbers from North to South America
- Common in group flights
3. Harris’s Hawk
- Known for hunting in cooperative groups
- Often seen in family units
4. Red-tailed Hawk
- Mostly solitary but may join small migratory groups
The Symbolism Behind a Group of Hawks
Hawks are often viewed as symbols of vision, focus, and freedom. But what happens when multiple hawks gather?
Spiritual Meaning of a Group of Hawks:
- Increased Awareness: A kettle may symbolize rising consciousness or spiritual awakening.
- Power in Unity: Multiple hawks represent combined strength and coordination.
- Transition: Seen during migration, a group of hawks may symbolize life transitions or personal growth.
In Native American traditions, hawks are messengers from the spirit world. A group sighting may be interpreted as a powerful omen.

Final Thoughts
So, what is a group of hawks called? The most accurate and evocative answer is a kettle—a swirling mass of birds riding invisible thermals high into the sky. But depending on the context, you might also hear terms like cast, boil, or simply flock.
While hawks may be solitary hunters most of the time, their brief but powerful gatherings during migration offer a stunning glimpse into the communal side of these fierce raptors.
