Make the lines visible. Day and night.

Bird strike kills far more birds than electrocution. Large species like eagles, swans, and brolgas are most at risk near waterways and migration corridors.

Identimark's bird diverter range makes overhead lines visible around the clock.Built on infrastructure marking, independently tested.

Birdmark Firefly bird diverter

Our bird diverter range.

Visual warning devices that make overhead lines visible to birds. Motion, reflective surfaces, and glow-in-the-dark materials alert birds during day and night. Installed directly onto lines at regular intervals along high-risk spans.

Firefly Spinning Diverter — Free-spinning with reflective surfaces for strong daytime visibility. Fits a wide range of line sizes.

tick-small

Birdmark Afterglow — Glows for hours after sunset. Critical night-time protection for nocturnal migration corridors.

tick-small

Universal Clamp System — Fits 6–16mm and 10–70mm conductors. One clamp range covers the full network, from distribution to transmission.

tick-small

UV-Stable Construction — Built from UV-stable, high-impact plastic. Engineered for long-term outdoor exposure without material degradation.

tick-small

Live-Line Installation — No outage required for retrofit on energised lines. Installed with hot stick tools.

tick-small

Flexible Spacing — Intervals tailored to terrain, species risk, and line layout. Closer spacing for high-risk zones.

Where bird diverters are specified.

Utilities, network operators, and environmental consultants across Australia and New Zealand rely on Identimark diverters for both new construction and retrofit.

Talk to us about your project

Transmission Lines
High-voltage corridors through wetlands, river crossings, and known flyways. Long-span installations where large-bodied species, eagles, swans, and pelicans, are most at risk.

Distribution Networks
Lower-height lines near urban waterways, agricultural land, and coastal environments. Retrofit programmes where live-line installation avoids costly outages.

Renewable Energy Infrastructure
Wind farm connection lines and solar farm corridors where environmental assessments require bird strike protection as a condition of approval.

FAQs.

What are bird diverters and how do they work?

Bird diverters are visual warning devices that make overhead lines visible to birds. They combine motion, reflective surfaces, and glow-in-the-dark materials to alert birds during both day and night. Devices are installed directly onto lines at regular intervals.

Can bird diverters be installed on live power lines?

Yes. Live-line installation with hot stick tools is the standard method. No outage required. Clamp fittings suit a wide range of line sizes for both new builds and retrofit.

How far apart should bird diverters be spaced?

Spacing depends on terrain, species risk, and line layout. High-risk zones like river crossings, wetlands, and known flyways need closer spacing. Contact us to determine the right coverage for your corridor.

Do bird diverters work at night?

Yes. The Birdmark Afterglow glows for hours after sunset. This matters because most migratory birds fly at night, making dusk to dawn the highest-risk window for collision.

When are bird diverters required?

Environmental assessments for new lines frequently require bird strike protection. Wildlife protection rules at both federal and state level create obligations for network operators in sensitive areas. Proactive installation is far more cost-effective than responding after incidents.
