Notes for property owners and feeders.
Birds are not put off by colours in general - they see in the same wavelengths we do plus some ultraviolet. But specific patterns do deter specific species. Bright white flashes deter most songbirds (reads as aggression or alarm). Predator-silhouette black shapes deter window-strikes. Yellow attracts hummingbirds; red attracts hummingbirds AND songbirds. The “what colour do birds hate” question is mostly the wrong question - it’s pattern and movement that matter, not pure colour.
What the research actually shows
Studies on avian colour vision and behavioural response converge on this:
- Bright white can deter approach, especially when it flashes (interpreted as alarm signal or as the white tail-flash of a fleeing bird).
- Predator-shaped silhouettes in any colour deter songbirds approaching windows - the SHAPE matters more than the colour.
- Bright yellow and red attract hummingbirds and some nectar-feeders.
- Blue has slight attractive properties for some songbirds (the blue feeder studies are mixed).
- No colour is universally repellent in itself.
The “colours birds hate” framing is largely folklore. What actually works to deter or attract is contrast, movement, and silhouette.
If you want to deter birds from a specific area
- Reflective strips (silver mylar tape) - the flash interpreted as flock alarm. Effective short-term against most species.
- Predator silhouettes (hawk-shaped stickers on windows) - reduces window strikes.
- Holographic ribbons or old CDs hanging - similar effect to mylar.
- Motion-activated objects (spinners, sprinklers) - the movement is what works.
Pure colour - painting your fence pink, say - does almost nothing.
If you want to attract birds
- Red feeders for hummingbirds - the colour cues that flowers use.
- Yellow flowers to attract goldfinches and some warblers.
- Plain wood or earth tones for nest boxes - the more natural-looking, the better.
- Bright bird baths are fine but the water is what attracts, not the colour.
The window-strike question
A big practical use of “what birds don’t like” is preventing window strikes - the leading cause of bird mortality in many regions. The colour-based answer:
- Black hawk silhouettes on the outside of glass work moderately well.
- External patterned tape or window stickers in any colour work better than transparent glass.
- The pattern density matters more than colour - lines or dots spaced no more than 4 inches apart deter most species.
Cultural folklore vs reality
A few colour beliefs that are NOT supported:
- “Birds hate the colour red.” No - many are attracted to red.
- “Painting your barn purple keeps birds away.” No effect.
- “Black scarecrows are more effective than white ones.” No measured difference; scarecrows in general lose effectiveness within days because birds habituate.

The bottom line
The question “what colours do birds not like” assumes a wrong frame. Birds respond to pattern, movement, and silhouette - not to colour as such. If you need to deter birds, use reflective flash or predator silhouettes; if you want to attract them, focus on feeders and habitat, not paint.
