Avian introductions refer to the deliberate or accidental introduction of bird species into new environments where they are not native. This can occur through human activities such as the release of captive birds, deliberate introduction for hunting or aesthetic purposes, or unintentional transport of birds via human commerce or migration. Avian introductions can have various ecological and socioeconomic impacts, including competition with native species, predation on local wildlife, spread of diseases, and disruption of ecosystem dynamics. Researchers studying avian introductions aim to understand the mechanisms and consequences of these introductions in order to inform conservation and management efforts.
