The most cost-effective way to ensure that buildings are bird-friendly is to build them that way in the first place, and to integrate bird-safe measures from the start of the planning process. However, there are also various products and strategies available to retrofit existing buildings.

See the links below for detailed information on bird-friendly design, and for a summary of products suitable for commercial/institutional application.

Following the most recent guidelines and best practices will help ensure that bird-friendly measures are as effective as possible. Don’t waste your money or efforts on techniques that do not meet current standards.

Architectural products

The following products have been tested by the American Bird Conservancy and/or the Fatal Light Awareness Program Canada. Most are not available for retail purchase. Contact an architect, glass supplier or contractor if interested.

Bird-friendly buildings need not cost more than other buildings if you consider bird-friendly design from the outset. Products listed here have Material Threat Factor Scores below 30 and are suitable for meeting the USGBC LEED™ Pilot Credit 55: Bird Collision Deterrence, and for meeting requirements of local ordinances in San Francisco, Toronto, Highland Park, Oakland, and others, as well as the State of Minnesota’s B3 guidelines.

CollidEscape

CollidEscape

Perforated window film, a.k.a. bus wrap, can be applied as a solid sheet, printed with a design, tinted, or laser-cut into stripes or other shapes for a customized pattern. It appears opaque from the outside in daylight, and like a screen from inside. The standard product is equivalent to a 50% window tint, and blocks heat and UV light while preventing collisions. However, the product will appear transparent at night from outside if the interior is lit, rendering it ineffective against nighttime collisions. CollidEscape is marketed specifically for bird-collision deterrence, but any perforated film will be effective. If cutting perforated film into stripes or shapes, please choose a high-contrast colour. We do not recommend CollidEscape Clear except for full coverage. Stripes or shapes of clear film do not produce enough contrast for most applications.

Goldray Industries Bird Friendly Glass

Goldray’s Bird Friendly Glass features pigmented glass enamel permanently fused to the first surface to reduce glare and provide visual noise. This first-surface ceramic frit is much more effective than a frit pattern applied to an interior surface, and is available in solid colors and patterns.

Goldray claims it has exceptional chemical, UV and weather resistant properties, which enable it to withstand the elements in exterior applications.

Arnold-Glass_Ornilux

Ornilux Low-e Neutral Adv. N33 & Low-e Neutral Uno N10 by Arnold Glas

Ornilux’s Mikado bird protection glass, according to their literature, prevents up to 71% of bird/window collisions. However, UV patterns are applied on the interior surface of the first layer of glass, and one study (Klem and Saenger 2013) concluded that the UV signal from Mikado is ineffective in alerting birds to the window hazard, and may even increase collisions.
