The Eastern Screech Owl is known for its distinctive calls, which include an even-pitched trill or bounce song, a shrill descending whinny, and, true to its name, screeches. These owls have two main types of calls: a descending, whinnying tremolo, and a soft, purring trill, both lasting 3 to 5 seconds. Interestingly, they are also known to sing antiphonally, with males and their incubating-brooding mates singing day and night, while neighbouring males sing synchronously at night.

Screech owls make two distinct sounds: a descending whinny and a soft trill
Screech owls are fascinating birds, and their calls are quite distinctive. They make two primary sounds: a descending whinny and a soft trill. These owls are not as loud or scary-sounding as their name suggests. Instead, their calls are quiet and mysterious, even a little eerie.
The first of these two calls is a descending, quavering whistle, described as a whinnying tremolo. This sound is used to defend territories and typically lasts only 0.5 to 2 seconds. It is interesting to note that this sound is quite similar to a horse's whinny, giving it its name.
The second sound is a soft, purring trill, sometimes referred to as a "bounce song." This call is used by pairs or families of screech owls to keep in touch with each other and typically lasts 3 to 6 seconds. It is a gentle, soothing sound. Young owls practice this call days before leaving the nest, and it is fascinating to hear the descending trill of the young birds as they prepare to fledge.
Both male and female screech owls sing, and they often sing together, either antiphonally (alternating singing) or synchronously (singing together). They may use these two distinct calls one after the other, creating a unique and captivating auditory experience.
Learning to imitate the call of a screech owl can be an enjoyable and rewarding experience. It involves listening to recordings and practicing until you can produce a similar sound. This process can enhance your connection with these mysterious birds and increase your appreciation of their unique place in the natural world.

The descending whinny is used to defend territories
The Eastern Screech Owl is known for its distinctive calls, which include a descending whinny and a soft, purring trill. These calls are quite short, lasting only three to five seconds. The descending whinny, in particular, serves a specific purpose for these owls: defending their territories.
The Eastern Screech Owl's descending whinny is a shrill, downward-sloping sound, resembling a horse's whinny in tone and pitch. This call is notably different from the soft, gentle trill that is also part of the owl's repertoire. The whinny is a territorial call, used to mark and defend the owl's home range. By producing this distinct and attention-grabbing sound, the owl asserts its presence and ownership of the area.
The Eastern Screech Owl is a nocturnal hunter, and its territorial behaviour is often most active at night. While both male and female owls are capable of singing, they may sing antiphonally, taking turns to produce the descending whinny call throughout the night. This duetting behaviour strengthens their territorial claims and helps them maintain control of their hunting grounds.
The descending whinny is a powerful tool for Eastern Screech Owls, allowing them to establish and protect their home territories effectively. It is just one of the many fascinating vocalizations used by these owls to communicate and navigate their world.

The soft trill is used by pairs or families to keep in touch
The Eastern Screech Owl is known for its distinctive calls, which include both a descending, whinnying tremolo and a soft, purring trill. These calls are typically used by pairs or families of owls to communicate and maintain contact with each other. The soft trill, in particular, serves as a means for owls to keep in touch and connect with their mates or offspring.
The soft trill of the Eastern Screech Owl is a gentle and subtle sound, often described as a purr. It is one of the two primary calls of this owl species, the other being the more energetic and dynamic descending tremolo. The soft trill is characterised by its low volume and tranquil quality, making it an ideal form of communication for owls to stay connected without drawing too much attention.
This particular call is often utilised by mated pairs, who sing antiphonally to each other throughout the day and night. The soft trill serves as a way for pairs to locate each other, reinforce their bond, and maintain a sense of closeness. It is also used by parents to communicate with their young, offering reassurance and a sense of security to their offspring.
In addition to its role in pair bonding and family communication, the soft trill may also be employed by incubating or brooding mates during the nesting period. This theory is supported by observations of nesting behaviour, where adult owls have been heard using the soft trill with their young, possibly as a form of training or encouragement to prepare them for leaving the nest.
The soft trill of the Eastern Screech Owl is a versatile and essential aspect of their vocal repertoire. By utilising this quiet and gentle call, owls are able to strengthen their familial bonds and effectively communicate within their social units. This behaviour showcases the complex social dynamics and strong family ties that exist within the world of Eastern Screech Owls.

Mated pairs sing to each other day and night
The Eastern screech owl has two distinct calls. One is a descending, whinnying tremolo, and the other is a soft, purring trill. Both calls last between three and five seconds and are rather quiet, mysterious, and eerie.
Mated pairs of screech owls sing to each other day and night, responding to one another's calls. These calls are an important part of their communication and bonding process. During the day, the owls may use softer, more subtle calls to maintain contact with one another as they hunt or go about their daily activities. As night falls, their vocalizations can become more frequent and varied as they establish their territory, seek out their mate, or exchange information about potential threats or food sources.
The male owl typically initiates the nighttime vocalizations, perching atop a tree or other tall object to emit his descending whistle, often described as a "whinnying tremolo." This call serves to announce his presence and claim his territory. The female owl, upon hearing her mate's call, responds with her own distinctive trill, a soft, purring sound that differs from the male's call in tone and pitch.
These nighttime duets can be quite captivating, with the male and female owls taking turns to vocalize and create a harmonious melody in the darkness. The intervals between their calls are usually brief, creating a back-and-forth conversation that strengthens their bond and reinforces their pair bond.
The owls' ability to distinguish each other's calls is quite remarkable. Even in the darkness, where vision is limited, they can identify their mate's unique vocalizations, ensuring they are communicating with the right partner. This specificity in their calls helps maintain the integrity of their pair bond and contributes to the overall harmony of their relationship.

Screech owls also make low hoots, loud barks, screeches, and clacking sounds
The Eastern Screech Owl is a vocal bird with a varied repertoire of calls and songs. While the name "screech owl" implies a loud and frightening sound, the truth is that their calls are quiet and mysterious, even eerie. The two most common sounds made by these owls are an even-pitched trill, often called a "bounce song" or tremolo, and a shrill, descending whinny. The tremolo is used by pairs or families to keep in touch and can last between 3 and 6 seconds. The whinny, on the other hand, is much shorter at 0.5 to 2 seconds and is used to defend territories. These two songs are often given one after the other.
Mated pairs of screech owls sing antiphonally to each other, both day and night. They also sing synchronously with neighbouring males at night. In addition to their trills and whinnies, screech owls also make soft, low hoots. They also have loud, sharp barking calls that indicate alarm or agitation. True to their name, they also screech, typically when adults are defending nests or fledglings.
When annoyed or agitated, screech owls make a clacking sound by snapping their bill mandibles together. This clacking sound is often heard when the owl is being mobbed or harassed. Additionally, captured screech owls may hiss as a threat display. While the owls typically call at night, they have been known to call during the daytime, especially when young owls are nearing the time to leave the nest.
Overall, the Eastern Screech Owl has a diverse range of vocalizations that serve various purposes, from communication and territorial defence to expressing alarm and annoyance. Their calls may be quiet and mysterious, but they are an integral part of the owl's behaviour and social interactions.
