Common Blackbird

About the Common Blackbird

Native to Europe, North Africa and western Asia, the common blackbird has become a severe agricultural pest in Australia and New Zealand following introduction in the 19th century. Highly adaptable, it thrives in urban gardens, orchards and forest margins.

Why it's a pest

Causes severe damage to viticulture and stone fruit orchards by pecking fruit directly on the vine or tree. A prolific disperser of noxious weeds including blackberry and olives through seed-bearing droppings, accelerating invasive plant spread across managed land.

A group is called

A cloud of blackbirds

Visual — describes the swirling, dark mass formed when hundreds of birds descend on fields or roosts simultaneously.

A grind of blackbirds

Comes from the continuous, low, grating noise a large group makes while rustling through dry leaves and soil for food.

How the APC-N1 and APC-N8 manages Common Blackbird

At approximately 250 mm, the common blackbird fits a T1 — Small tunnel (100 × 260 × 360 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 common blackbird 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 T1 — Small tunnel is available on the APC-N1 and APC-N8both units carry this tunnel size as a standard configuration.
