Threat Factor

Database Overview

ABC uses Threat Factors (TFs) to indicate the relative ability of materials to reduce collisions. Products with lower TFs are considered more effective at preventing collisions. A TF of 30 should reduce collisions by at least 50 percent and is ABC's upper threshold for categorizing materials as bird friendly. Learn more about Threat Factors.

Product Listing

Bird's Eye View

Artscape Inc.

Threat Factor: Variable. Effectiveness depends on visibility and spacing of visual markers.

intended for application to the inside of windows, non-adhesive, easy to apply, 2x2" spacing recommended. Field tested by Dr. Daniel Klem, on uncoated window glass glass

Marker Type: Decal
Product Line: Bird's Eye View

These decals, intended to be applied to the inside of the glass, have only been tested on ordinary window glass and may be less effective on windows with reflective coatings. 2x2" spacing is recommended.

Pattern: 2x2" spacing is recommended

Paint: Oil-based Pen

Any

Threat Factor: Variable. Effectiveness depends on visibility and spacing of visual markers.

Image drawn on outside of window, using oil-based pen

Marker Type: Paint Pattern

Painted images can be excellent collision deterrents but must follow guidelines for spacing and other pattern elements to be effective. The pattern shown here meets basic spacing criteria and monitoring at the University has shown it to be successful at reducing collisions.

Decals: bird silhouettes

Wandkings

Threat Factor: Variable. Effectiveness depends on visibility and spacing of visual markers.

Place decals using 2"x2" spacing guidelines

Marker Type: Decal
Product Line: Bird and Window Protection Stickers

Decals applied to the outside of the glass can be very effective, if applied with 2x2" spacing. Apply to the exterior side of the glass, first cleaning the surface. Many commercial window cleaners leave a residue that can interfere with adherence. We recommend using a 50% water/50% rubbing alcohol solution. Make sure the glass surface is completely dry before installation.

Color: Black
Pattern: 2x2" spacing is recommended

Paint: Tempera

Any

Threat Factor: Variable. Effectiveness depends on visibility and spacing of visual markers.

Use non-toxic paint to put up pattern or picture using 2x2" spacing guidelines

Marker Type: Paint Pattern

Tempera is a quick, inexpensive solution for collisions. It can be applied casually, or with a stencil , to the outside of the glass. You could create different patterns for every holiday. Patterns last a surprisingly long time, even after rain, but can be removed almost instantly.

Color: Any
Pattern: Multi

WindowAlert Decals (multiple styles)

WindowAlert

Threat Factor: Variable. Effectiveness depends on visibility and spacing of visual markers.

Recommend installation with 2" x 2" spacing

Marker Type: Decal
Product Line: WindowAlert
Color: frosted + UV
Pattern: multiple patterns

Paint: Acrylic

Any

Threat Factor: Variable. Effectiveness depends on visibility and spacing of visual markers.

Use non-toxic paint to put up pattern or picture using 2x2" spacing guidelines

Marker Type: Paint Pattern

Paint of all types can provide inexpensive, long lasting and highly effective solutions for glass collisions. Plan carefully for acrylic or oil paint, as they may be difficult to remove.

Color: Any
Pattern: Multi

Masonry

Threat Factor: 1

Prescriptive; reflection test

Marker Type: No Reflection

Stucco, concrete, brick and stone with a matte finish should be safe for birds in any application.

Color: any
Pattern: patterned or smooth

Insect Screen

Any Insect Screen

Threat Factor: 1

Prescriptive evaluation; reflection test

Marker Type: Physical Screen

Insect screens eliminate problem reflections and reduce impact if a bird does hit a window. If possible, use screens that cover the entire glass area of a window.

Glass: stained

Any Stained Glass

Threat Factor: 1

Prescriptive rating

Marker Type: Low Reflection

Stained glass in general is very bird-friendly, as well as serving purposes of devotion or decoration. There is even photovoltaic stained glass! However, if a stained glass panel is insulated, by mounting an external ‘storm window’, it is important to make sure that reflections from that panel of glass don’t cause collisions.

Pattern: panels entirely comprising pieces of different colored/textured, translucent, non-reflective glass
