FUNCTIONAL SIGNIFICANCE OF DISTRESS CALLS Distress calls are emitted by adult birds which are physically constrained by a predator (Schmidt and Johnson 1984) and are distinctive from alarm calls (Thompson et al.
Alarm calls can be wide-bandwidth, loud and short to attract birds from farther away to come mob a predator. Other calls can be shorter bandwidth, high-pitched “seets”that don't travel as far as individual sounds, but spread quickly from bird to bird to warn of a predator on the move.
Summary: Birds' alarm calls serve both to alert other birds to danger and to warn off predators. And some birds can pull a ventriloquist's trick, singing from the side of their mouths, according to a new study. Birds' alarm calls serve both to alert other birds to danger and to warn off predators.
One of the best sounds to get birds to scatter (and perhaps not to return) are synthetic sounds such as high-frequency, ultrasonic sounds. If you add in a frightening visual object such as an owl statue or scarecrow with shimmering tassels, the strategy becomes all that much more effective.
“Danger!” The Whinny is an alarm call given by males and females. It expresses a higher level of alarm that Peek and Tut. Neighboring robins often fly in when they hear this to help mob a predator. The call sounds like a whinnying horse.
Birds give a lot of “false alarms” or brief low-level alarms. With practice you will become sensitive to the higher intensity of real alarm calls, and when these calls are sustained for several minutes, and directed at one spot, you can be fairly certain a predator is there.

Generally speaking, birds hate strong smells, shiny objects, and predators, both birds of prey or larger animals or humans within their vicinity.
Deterrents for magpies
Half-full plastic bottles or CDs hung up in trees to scare the predators away. Magpies don't like the way light reflects from the surface. GuardnEyes scarecrow balloon, available from Dazer UK. It may be possible to deter them by playing a tape of a crow or rook distress call.
For example, a seet is the universal danger call made by birds and small mammals. Chickadees, it turns out, chirp about predators a lot. In fact, their name comes from the warning call they make when they see a suspicious character lurking around the neighborhood: Chickadee-dee-dee-dee-dee.
Recognising Stress in Your Pet Birds
Look at the bird's feathers for an indication if they suffering stress lines. Aggression – If your bird suddenly has a change in their demeanour and becomes aggressive, this could be a sign of stress. Biting, hissing, lunging, and excessive screaming are all signs to watch out for.
Birds make contact calls to keep in touch with each other, often while they're foraging for food. These sounds are usually short, quick, and quiet, though if birds get separated, they may make louder, more urgent “separation calls.”
Echo the lyrebird appears to have learned how to perfectly replicate the sound of a wailing baby. The bird, who lives in a Sydney zoo, can also mimic a fire alarm and power drill, a zoo official said.
Like many owls, Barred Owls initiate their vocal courtship in winter. And they're among the most vocal. These owls have more than a dozen calls, ranging from a "siren call" to a "wail" to a wonderfully entertaining "monkey call." Barred Owls are among the largest owls in North America.
Alarm calls
In the vocabulary of some birds, there is one alarm call specifically to warn of aerial predators, and another alarm call used in other circumstances, for example, when a ground enemy appears.
Keep Animals Away
The lubricant also works as a pigeon repellent on balconies and roofs, because the birds hate its smell.
The new findings add to the growing evidence that many animals can smell one another's fear, including species not known for their bloodhound powers. Birds and humans in particular were long thought to rely on vision and hearing rather than smell when sizing up the world and its ambient threats.
The Smell of Food.
Birds love the smell of food or at least the smell of stuff that indicates the presence of food.
Yes, extreme stress can cause a bird to die. It's more about stress than fright. She may have already been stressed because of the string, if it had been caught for a while. Birds also need to be able to move their chest up and down to breathe.
Nocturnal birds have a highly developed sense of night vision, enabling them to fly, hunt, mate, and raise young in darkness. Most bird species are adapted for better vision during daylight hours, with only limited eyesight once night falls.
Parrots and some other species of birds are known to be extremely empathetic and tuned into the emotional environment around them. They can sense stress and tension, anger and distress in their owners, before these bubbling feelings break the surface.
Birds tend to get very quiet before a big storm. If you've ever been walking in the woods before a storm, the natural world is eerily silent! Birds also sing if the weather is improving. Birds singing in the rain indicates fair weather approaching.
Birds may leave in advance of an approaching storm
Research has shown that birds can hear infrasound (ref) and are sensitive to barometric pressure (ref and ref), so they know when a storm is on its way -- especially when the storm is as large and as powerful as a hurricane.
Scientists believe it is the birds' ability to hear infrasound — low-frequency sounds inaudible to humans — that allows the birds to sense storms and tsunamis coming.
