The decals are UV-reflective and can be applied to glass windows and sliding doors. Each pack contains five leaf designs that blend with home décor while serving as a deterrent. No adhesive is required for installation, and the material is described as frosted or etched to humans, preserving window aesthetics.
48 Pieces Birds Static Window Clings

These 48 pieces offer a variety of bird-strike deterrent clings designed to reduce collisions on windows and glass doors. The set uses translucent prismatic vinyl to catch sunlight and create rainbows, providing visual cues for birds. Installation is static-based, with no adhesive, enabling easy removal and reuse. The decals are suitable for both indoor and outdoor placement, and users can spray a light mist of water to help the cling settle. Residue-free removal is highlighted as a benefit.
Anti-Collision Window Bird Stickers (Clear)

These clear anti-collision decals are designed to be minimally visible from afar while providing a protective barrier for birds. Made of PVC, they are intended to be mounted on the outside of windows or doors, though installation inside is possible if needed. The decals help reduce bird strikes by creating a noticeable pattern or obstruction that birds recognize as a barrier.

This 26-piece set features leaf-shaped clings with a transparent matte finish to maintain clear views while providing a visual barrier for birds. The decals are made from high-quality PVC designed for durability and fade resistance. Application is easy: spray water, peel from the backing, and stick to smooth glass surfaces with no tools required. They are non-residue and reusable, making repositioning straightforward.
36 Pieces Window Decals for Bird Strikes

Includes a mix of bird-oriented motifs (bird, butterfly, leaf, etc.) in 36 pieces. The rainbow prism effect helps deter birds by breaking up reflections on glass surfaces. The decals are non-adhesive and reusable, relying on static cling for application. The varied sizes (from small to larger leaves) allow diverse window coverage and creative displays, while remaining gentle on glass and easy to remove.
81 Pieces Circle Window Decals for Bird Strikes

This set offers 81 circular, non-adhesive vinyl decals designed to create a rainbow-sprinkled barrier. The bright colors are intended to be visible from both sides of the glass, helping to deter birds while preserving visibility for people. The static cling design enables easy removal and repositioning without leaving residue, and the stickers come in a variety of sizes to fit large and small panes alike.
Buying Guide
Key purchase considerations include visibility and placement, ease of installation, and whether you prefer adhesive-free solutions. Non-adhesive static clings are gentle on windows and can be reused, which suits renters or seasonal use. For high-traffic sunlit areas, UV-reflective designs may provide stronger deterrence by catching light and appearing as a warning to birds. Consider the window size and the degree of visibility you need from both inside and outside. If you want a decorative touch, prism colors and rainbow effects can still offer bird protection without looking cluttered. Durability, ease of removal, and potential impact on glass clarity are also important to weigh. For broader coverage, multi-pack sets with varied shapes and sizes provide flexible arrangement options for larger windows or patio doors.
Another perspective to consider is whether you want outside, inside, or dual-location installation. Outside mounting tends to be more immediately visible to birds approaching from outdoors, while inside mounting can be less conspicuous to people. Non-residue, reusable decals reduce long-term maintenance and window abrasion. For households with multiple windows or patio doors, selecting a kit that includes a mix of shapes and sizes can maximize deterrence without sacrificing window aesthetics. Finally, verify that materials are safe for indoor use and compatible with your climate to ensure longevity and color retention over time.
