WindowAlert Snowflake Anti-Collision Decal 12 Pack - UV-Reflective

Our review of the WindowAlert Snowflake Anti-Collision Decal 12 Pack finds it best for homeowners and renters who want a low-visibility, wildlife-friendly way to reduce bird strikes on glass. The bottom line: these semi-transparent, static-cling snowflake decals use a UV-reflective material that birds see as a warning while remaining subtle to people, making them a practical choice for sliding doors, larger windows and multi-pane facades where minimizing visual clutter is important.

Key Features

• 12-pack with 4 decals per pack: Provides a ready supply of small decals so you can cover multiple windows or replace a few after repositioning.
• Semi-transparent, static-cling material: Applies without adhesive and appears as frosted or etched glass to humans while clinging to exterior glass.
• UV-reflective design: Reflects ultraviolet sunlight to create a visible warning for birds while staying subtle to human sight.
• Approximately 3.5 in across: Small, discreet size that works well on panes, patio doors, and narrow sections of glass without obstructing views.
• Made in the USA: Manufactured domestically by a brand that pioneered UV window decals, supporting product consistency and quality.

Who It's For

This product suits homeowners, birders and conservation-minded renters who want a non-permanent, low-profile deterrent for bird collisions on windows and sliding doors. It is especially fitting where aesthetic concerns matter, since the snowflake designs blend with decor and do not heavily obscure views.

Those who need reusable stickers for interior glass, large-format patterned films for full window coverage, or products compatible with heavily coated or tinted glass should look elsewhere; WindowAlert decals are designed for one-time exterior application to clean, untreated glass surfaces.
