WINDOWALERT Classic Square Anti-Collision Decal – 4-Sheet UV-Reflective Bird Deterrent – Made in USA

Protect Birds, Preserve Your View with WINDOWALERT

The WINDOWALERT Classic Square Anti-Collision Decal comes as a four-sheet bundle of semi-transparent, static-cling decals designed for exterior glass surfaces. Each sheet holds four reflective decals, and the decals measure about 3.5 inches across. The set provides sixteen decals in total, a versatile option for various window sizes and configurations. The UV-reflective material glows under sunlight, creating a visible warning sign for birds while appearing frosted or etched to human observers. This bundle is proudly made in the USA and reflects the brand’s long-standing commitment to wildlife-friendly design that began with ultraviolet window decals in Bend, Oregon in 2003.

What’s in the 4-Sheet Bundle

• Four sheets total, each with four decals (16 decals overall)
• Semi-transparent, classic square designs that complement modern home décor
• Each decal is approximately 3.5 inches across for versatile window coverage
• Designed for exterior glass surfaces and easy to reposition on a clean, dry surface

How It Works

The reflective material catches UV sunlight and glows as a warning signal for wild birds, potentially helping them recognize glass as an obstacle. To people, the decals read as frosted or etched glass, preserving visibility while adding a discreet wildlife deterrent.

Installation Tips and Best Practices

• Prepare a clean exterior glass surface free of overlays, tinting, film, or coatings
• Apply decals to the outside of the window for best visibility; static cling allows easy repositioning
• Consider planning placement across multiple panes to create a cohesive, bird-safe pattern
• If repositioning is needed, simply lift and re-stick while the surface remains free of debris
