A silent call is a telephone call in which the calling party does not speak when the call is answered. Most such calls are generated by a cold call telemarketing operation's dialer software, which makes many calls automatically and sometimes does not have an agent immediately available to handle an answered call.
Alarm calls have been studied in many species, such as Belding's ground squirrels. Characteristic 'ticking' alarm call of a European robin, Erithacus rubecula. In animal communication, an alarm signal is an antipredator adaptation in the form of signals emitted by social animals in response to danger.
Freezing occurs early during a predator-prey interaction when the prey detects and identifies the threat, but the predator has not yet seen the prey. [1] Because freezing occurs before detection and is used to better camouflage the prey and prevent the predator from attacking, it is considered a primary defense mechanism.
The team split up, and the half that first saw Conradt at the end of a hallway variously described his last words as some variation of "I am not gonna hurt anybody." He then shot himself in the temple with a Browning.380 pistol, [9] and died within 60 minutes. [11]
Spirama helicina resembling the face of a snake in a deimatic or bluffing display. Deimatic behaviour or startle display [1] means any pattern of bluffing behaviour in an animal that lacks strong defences, such as suddenly displaying conspicuous eyespots, to scare off or momentarily distract a predator, thus giving the prey animal an opportunity to escape.
When the nest was approached, the female attempted to lead the researcher away through the trees using a ventriloquistic call that resembled the cries of the young. [12] An additional study documented distraction display in Mentawai langurs , whereby a male will call loudly and bounce on branches while the female and young are able to quietly hide.

Individuals living in large groups may be safer from attack because the predator may be confused by the large group size. As the group moves, the predator has greater difficulty targeting an individual prey animal. The zebra has been suggested by the zoologist Martin Stevens and his colleagues as an example of this. When stationary, a single ...
