The bird sound most often described as "snoring" comes from Hummingbirds in torpor, a deep sleep state to conserve energy, but Barn Owl chicks also make a similar rasping, snoring-like begging call, and sometimes Nightjars have a rattling/snoring call. Hummingbird snores are high-pitched and tiny, while barn owl chick sounds are louder and more rasping.
The weak call of the male Pickerel Frog sounds like someone snoring in the distance. The males usually call in May, and eggs are laid and attached to submerged vegetation. The adult pickerel frog is most often seen along the edges of streams or flooded ditches.
Rhonchi. Rhonchi (plural of the word rhonchus) are continuous, low-pitched sounds that are best heard when you're breathing out (also called “expiration”). The sound might move around to different parts of your chest when you cough, moving mucus around. The sound is sometimes described as snoring or gurgling.
Then there are also birds like the Bush Stone-curlew and the ever elusive Night Parrot that are nocturnal as well and a range of day-time birds like Willie Wagtails, Eastern Koels and Masked Lapwings that will also call a lot at night, particularly during their breeding season.
Science Behind the Adorable Sleeping Hummingbird. The fascinating hummingbird in this video that appears to be snoring is actually in a state of torpor. Torpor is a state of decreased physiological activity (like a short-term hibernation), which allows an animal to conserve energy.

The most commonly heard call of the Large-tailed Nightjar is a monotonous series of hollow “chonk, chonk, chonk…” notes which sound a bit like a distant chopping or knocking on wood. These sounds are most frequently given just after dusk or just before dawn.
Common Brushtail Possum (Trichosurus vulpecula) – This is the rufous form common in Tasmania. Another of the more disconcerting sounds of the Australian bush at night, the throaty coughs and growls of a Common Brushtail Possum (Trichosurus vulpecula) sounds more monster than fluffy marsupial!
These medium-sized nocturnal or crepuscular birds are noted for their long wings, short legs, and stout bills. The tawny frogmouth is active at night; by day it perches in trees perfectly camouflaged. They are native to Australia and also found on Tasmania.
The deep, slow 'woo-hoo' call is diagnostic of Powerful Owl and is generally lower-pitched and more drawn out than the typical calls of the Southern Boobook (Ninox boobook). Powerful Owls also make a few other sounds including soft bleating calls, growls and young birds make high-pitched trills.
People commonly mistake sleep apnea and snoring as synonyms, but they are far from it. Even though loud snoring can be a visible symptom of this disorder, some other symptoms accompany sleep apnea, the main one being pausing in one's breath.
Rhonchi. Sounds that resemble snoring. They occur when air is blocked or air flow becomes rough through the large airways. Stridor.
The AASM continues to recommend scoring hypopneas in adults when there is a ≥ 3% oxygen desaturation from pre-event baseline and/or the event is associated with an arousal.
Any mammal with soft tissue surrounding its airways has the ability to snore.
Snoring isn't normal behavior for most birds, although it's reported that some large birds sometimes make audible sounds of breathing when they're asleep. In general, birds are silent when they're sleeping.
Male limpkins are well known for producing a repetitive, high-pitched wail or scream that sounds remarkably human-like when it wakes you up in the dead of night.
Spiritually, hearing an owl hoot is a sign of needing to set energetic boundaries. Owls carry with them very protective energy and could be warning you of harmful people in your life.
Tawny Frogmouths are not rare at all, being common and widespread across Australia, even in urban areas, but they are hard to spot due to their incredible camouflage and nocturnal habits, often mistaken for a broken branch. While populations are generally stable, they face threats like habitat loss (especially old trees for nesting), roadkill, and pesticide poisoning, but are listed as a species of "Least Concern".
There are many birds that are active nocturnally. Some, like owls and nighthawks, are predominantly nocturnal whereas others do specific tasks, like migrating, nocturnally.
The “Snoring” of Barn Owl Chicks
All nestlings produce begging calls to signal that they're hungry. But while most begging calls are high-pitched chirps and peeps, the begging call of barn owl chicks is a rasping sound that can be compared to human snoring [1].
Australian Owlet-nightjar – Variations of Typical Calls
Although most-commonly heard at night, Australian Owlet-nightjars can sometimes be heard calling from their roosting hollows during the day. The bell-like notes in this sample are from a Crimson Rosella.
Most possum activity begins after dusk and continues through the night, with peak noise occurring between 10:00 PM and 4:00 AM. Their sounds can range from soft chattering to full-blown screaming, depending on the situation and species.
The bird that makes a "woop woop" sound in Australia is most commonly the Pheasant Coucal (Centropus phasianinus), a large cuckoo known for its deep, bubbling, whooping calls that sound like "oop-oop-oop" and are often heard in marshy areas, cane fields, or thickets, often in duet with a mate, especially during spring and summer.
The Australian bird that screams at night, often sounding like a woman or baby wailing, is the Bush Stone-curlew (also called Bush Thick-knee), known for its eerie, high-pitched contact calls used at night in woodlands and grasslands, sometimes in a chorus, and is famous for its haunting, mournful sounds.
