What is a Hawks Cry Called? Exploring Avian Vocalizations
The primary sound a hawk makes is called a scream, although hawks also utilize a variety of other vocalizations for communication. It’s a piercing and distinctive sound often associated with wild landscapes.
Understanding Hawk Vocalizations
Hawks, magnificent birds of prey, communicate through a range of vocalizations. While the term “cry” is often used generically, understanding the specific sounds hawks make and the purposes behind them provides deeper insight into their behavior and ecology. What is a hawks cry called? Beyond the scream, hawks employ a repertoire of calls, whistles, and other sounds.
The Hawk Scream: The Signature Sound
The most recognizable sound produced by a hawk is undoubtedly its scream. This piercing, high-pitched call serves multiple functions:
- Territorial Defense: Hawks use their screams to announce their presence and defend their hunting grounds from rivals.
- Mate Attraction: During breeding season, the scream plays a crucial role in attracting potential mates and solidifying pair bonds.
- Communication with Young: Parent hawks utilize the scream to communicate with their chicks, signaling danger or calling them to food.
The intensity and frequency of the scream often vary depending on the situation. A hawk defending its nest might emit a series of rapid, urgent screams, while a hawk soaring overhead might produce a single, drawn-out scream.
Beyond the Scream: A Diverse Vocal Repertoire
While the scream is the most well-known hawk vocalization, hawks are capable of producing a variety of other sounds. These sounds, often more subtle than the scream, play important roles in their communication.
- Chirps: These soft, high-pitched sounds are often used by parent hawks to communicate with their young chicks, providing reassurance and encouragement.
- Whistles: Some hawk species, such as the Northern Goshawk, produce a series of whistles, often used during courtship displays.
- Calls: Hawks emit various calls for different purposes. The keer-keer-keer call of the Red-tailed Hawk is one such example, often heard when the hawk is disturbed.
- Begging calls: Young hawks will use distinct begging calls when attempting to solicit food from their parents.
Factors Influencing Hawk Vocalizations
Several factors influence the vocalizations of hawks, including species, age, sex, and social context.
- Species-Specific Sounds: Different hawk species possess unique vocal repertoires. The scream of a Red-tailed Hawk sounds distinctly different from the scream of a Cooper’s Hawk.
- Age-Related Changes: Young hawks often have higher-pitched voices than adults, and their vocalizations may be less refined.
- Sex Differences: In some hawk species, males and females produce slightly different vocalizations, particularly during courtship displays.
- Social Context: The type of vocalization a hawk emits depends heavily on the situation. A hawk defending its territory will use different vocalizations than a hawk hunting prey.
The Evolutionary Significance of Hawk Vocalizations
Hawk vocalizations have evolved over millennia to serve specific purposes. Effective communication is crucial for survival, allowing hawks to defend their territories, attract mates, raise their young, and hunt effectively. The high-pitched scream, for example, is well-suited for traveling long distances and penetrating dense foliage, ensuring that the message reaches its intended recipient.
Using Vocalizations to Identify Hawks
While visual identification is often the primary method for identifying hawk species, their vocalizations can provide valuable clues. Learning to recognize the distinctive screams and calls of different hawk species can greatly enhance your birdwatching skills. Many online resources provide audio recordings of hawk vocalizations, allowing you to familiarize yourself with their sounds.

Frequently Asked Questions (FAQs)
What is a hawks cry called when it is defending its territory?
When defending its territory, a hawk’s cry, particularly the scream, becomes more frequent and intense. The scream serves as a warning to intruders, signaling that the territory is occupied and should not be encroached upon. It’s a powerful display of avian ownership.
What other sounds, besides the scream, do hawks make?
Besides the signature scream, hawks also produce chirps, whistles, and various calls depending on the context. These can be softer sounds used for communication with offspring or more complex vocalizations employed during courtship rituals. Knowing what is a hawks cry called beyond the scream helps you identify different species.
Do all hawk species have the same cry?
No, different hawk species have distinct vocalizations. While many use the scream, its specific characteristics, such as pitch, duration, and frequency, vary considerably between species. Learning to differentiate these variations can assist in identifying hawks by sound alone.
Why do hawks scream?
Hawks scream for a variety of reasons, including territorial defense, mate attraction, and communication with their young. The scream is a versatile signal that serves multiple purposes in the hawk’s daily life, vital for survival and propagation. What is a hawks cry called often depends on why it is used.
Are hawk cries different between males and females?
In some hawk species, there are subtle differences between the vocalizations of males and females. These differences are often more pronounced during courtship displays, with males using specific calls to attract potential mates.
How does the age of a hawk affect its vocalizations?
Young hawks often have higher-pitched voices than adults, and their vocalizations may be less refined. As they mature, their vocal cords develop, resulting in deeper, more resonant sounds.
Can I identify a hawk by its cry alone?
While challenging, it is possible to identify some hawk species by their cry alone, especially if you are familiar with the specific vocalizations of common local species. However, visual confirmation is always recommended.
What time of year are hawk cries most frequently heard?
Hawk cries are most frequently heard during the breeding season, when hawks are actively defending their territories and attracting mates. Spring and early summer are typically the peak periods for hawk vocal activity.
Do hawks cry when they are in pain?
While difficult to interpret, it is plausible that hawks may emit distress calls when in pain or injured. However, these calls are not well-documented and are likely to be distinct from their typical vocalizations.
What can I do to learn to identify hawk cries?
Listen to audio recordings of hawk vocalizations online, practice identifying them in the field, and consult with experienced birdwatchers or ornithologists. Familiarizing yourself with the sounds of different hawk species takes time and practice.
Are there any other birds that sound like hawks?
Some birds, such as Blue Jays, are known to mimic the screams of hawks. This mimicry may serve to deter other birds from the area, giving the Blue Jay an advantage.
What is a good resource for learning more about hawk identification, including by sound?
The Cornell Lab of Ornithology’s website and Merlin ID app are excellent resources for learning more about hawk identification, including by sound. These resources provide detailed information, audio recordings, and visual aids to help you improve your birdwatching skills. Knowing what is a hawks cry called is made easier by using such resources.
