Native to sub-Saharan Africa and Iraq, the sacred ibis has established large invasive populations across Western Europe, particularly France, Italy and Spain, following escapes from zoos and wildlife parks. Populations in Taiwan have also become established. A colonial nesting waterbird that forms dense breeding colonies.
Displaces native waterbirds including herons, egrets and spoonbills through aggressive nest predation, destroying eggs and chicks of competing species. Presents a significant aviation bird-strike hazard at coastal and inland airports due to large body mass and flock behaviour. Contaminates water bodies and wetlands with heavy faecal deposits.

A congregation of ibises
Has religious undertones, linking back to Ancient Egypt where the bird was revered and worshipped as a symbol of the god Thoth.
A stand of ibises
Visual — describes their statuesque, upright posture while wading motionless in shallow water waiting for prey.
A colony of ibises
Biological — refers to their large shared nesting and foraging grounds in wetlands or landfills.
At approximately 750 mm, the sacred ibis fits a T4 — Extra Large tunnel (160 × 900 × 1050 mm). The tunnel is the physical entry point — sized precisely to admit the target species while excluding larger non-target birds. Species-specific attractant bait draws the sacred ibis into the detection zone inside the tunnel, where AI computer vision confirms species identity at 99.7% accuracy. Once confirmed, CO₂ is introduced gradually into the chamber; the bird becomes drowsy and loses consciousness without pain or distress. Euthanasia follows only after explicit authorisation from a licensed operator, and the specimen is stored in the integrated freezing chamber with a full compliance audit trail.
The T4 — Extra Large tunnel is available on the APC-N1 and APC-N4 — both units carry this tunnel size as a standard configuration.

Tunnel size is set by the species' standing height — sized to admit the target bird while excluding larger non-target species.
