Quck answer
Different bird species can communicate with each other, but the extent and effectiveness of their communication can vary. Some birds use alarm calls to alert others of potential danger, while others use complex songs to attract mates or defend territories. Some species may even mimic the calls of other birds or animals for various purposes. However, not all birds are able to understand or respond to the calls of other species, and some communication may be misinterpreted or ignored altogether. Ultimately, the ability for different bird species to ‘talk’ with each other depends on the specific context and individuals involved.

A skilled bird-watcher can identify local bird species not only by sight, but also by sound. This is known as “birding by ear” and with practice and a good field guide, enthusiasts learn to recognize the unique “tweets,” “cheeps,” and “hoots” of different birds. To master this skill, one must have a basic understanding of how and why birds communicate. Typically, a species will use its own distinct set of sounds, such as mating calls and territorial threats, to convey different messages. For instance, rock pigeons court each other with gentle coos and use harsh grunts to signal distress. To survive and reproduce, an individual rock pigeon must be able to recognize both vocalizations.
But what do a pigeon’s sounds mean to passing crows or cardinals? Can birds comprehend the calls of other species?
We recently spoke with Robert D. Magrath, an ornithologist and behavioral ecologist at the Australian National University, about interspecies communication among birds. Magrath has co-authored numerous studies on the topic, focusing particularly on avian alarm calls—warning cries that birds emit when they spot a predator.
Magrath explains, “Nearly every bird species we have studied locally respond to other species’ alarm calls, and we suspect eavesdropping on other species’ calls is widespread around the globe. This is not surprising given that almost all species are vulnerable to predators and should use any available cues to detect their presence.”

One example of interspecies communication can be seen in the relationship between black-capped chickadees and red-breasted nuthatches. These two songbirds have much in common; they are indigenous to North America, are similar in size, and are wary of raptors. When chickadees spot a goshawk, owl, or other predator, they issue an alarm call. These warnings recognize different threat levels with high-pitched “seat” calls used to alert other birds of a raptor flying far overhead, and a “chick-a-dee-dee” cry for a perched raptor nearby. Extra “dees” are added if the predator looks particularly dangerous.
Studies have shown that red-breasted nuthatches understand the chickadee’s warnings and can decode the exact level of danger being signaled. Clearly, eavesdropping has its advantages.
Alarm calls can even elicit a response from non-avian listeners. For example, the tufted titmouse is a songbird whose anti-raptor warning cries cause squirrels and chipmunks to flee. These mammals are known to spread the distress signal by mimicking it with their own voices. Sparrows, cardinals, and jays also mimic the titmouse’s signature alarm call, creating an interspecies chorus to alert others of an oncoming threat.
So, do birds innately understand other species’ alarm calls, or do they learn to identify them over time?
Magrath explains that, in some cases, certain birds actively learn to recognize the cries. Superb fairy wrens are a common sight on the Australian National University campus in Canberra, which is also frequented by a grey bird called the noisy miner.
Magrath discovered that superb-fairy wrens fled when they heard miner alarm calls in one of his studies, but those at the botanical garden across the street did not react to the same recording. This suggests that call recognition between species must be learned rather than innate. Magrath even trained fairy-wrens to recognize new sounds as alarm calls by pairing them with the presentation of hawk models, which proves that learning is possible. Birds can also recognize the sounds of other species if there is a benefit to recognition, such as defending territories or finding food. Baby cuckoos imitate the begging cries of their host species to trick them into raising their young. Kookaburras are known for their distinctive cackle, which has been featured in popular films.
FAQ
1. Can different bird species communicate with each other?
Yes, birds of different species can communicate with each other. However, the extent of their communication may vary depending on the species. Some bird species have similar vocalizations, which allows them to understand each other’s calls. Others may not understand the calls of different species but can still communicate through body language and behavior.
2. How do birds communicate with each other?
Birds communicate with each other in various ways, including vocalizations, body language, and behavior. Vocalizations are the most common way of communication, with birds using different calls and songs to convey different messages. Body language, such as head bobs and wing flaps, can also be used to communicate. Behavior, such as displaying aggression or submission, can also convey a message.
3. Do birds learn to communicate from other species?
Yes, some bird species can learn to communicate from other species. This is particularly true for birds that are raised in captivity or live in urban environments where they are exposed to different bird species. Learning from other species can also occur in the wild when birds live in close proximity to each other and are exposed to each other’s vocalizations.
4. Can birds use the same call for different meanings?
Yes, birds can use the same call for different meanings. For example, a bird’s call may vary depending on the context in which it is used. A call that is used to signal danger may sound different from a call used to attract a mate. Birds can also use the same call to convey different emotions, such as fear or aggression.
5. How do birds of different species benefit from communication?
Birds of different species can benefit from communication in various ways. For example, communication can help birds to locate food sources, warn each other of danger, and locate potential mates. Communication can also help birds to form social bonds and establish dominance hierarchies within their social groups.
6. Can humans understand bird communication?
Humans can understand some aspects of bird communication, such as recognizing different calls and songs. However, the complexity of bird communication is not fully understood, and there may be aspects of bird communication that are beyond human comprehension. Scientists are continually studying bird communication to gain a better understanding of how birds communicate with each other and the role that communication plays in their behavior and social interactions.
