| Many vocalisations may have either a positive or a negative meaning, depending on the type, length and pitch of the sound produced. |
| But these vocalisations should not be elevated to the status of human communications. |
| These vocalisations are not unique to the house sparrow, but are shared, with small variations, by all sparrows. |
| They thus learn to socialise and, frequently through vocalisations, discover what may be dangerous or beneficial for them. |
| Studies have shown these vocalisations to sometimes communicate information that is functionally important for feeding, breeding, parental care, predator avoidance, or maintenance of social groupings. |
| Your horse learns words, phrases, body language and vocalisations so that it can understand you and guess what you're going to do next. |
