| Bill | Yellow during breeding season in adults; darker when not breeding. |

European starlings (Sturnus vulgaris) are invasive in North America. In Greater Vancouver they exploit roof vents, soffit gaps, and signage letters for nesting. Large winter roosts create noise and droppings in downtown edges and industrial blocks.
Behaviour & Habits
They nest in cavities—natural and human-made. Dryer and kitchen exhaust vents without flaps are classic spring blockages. Flocking behaviour concentrates birds at roosts where heat islands help overnight survival. They feed on lawns, berries, and human food waste.
Health & Property Risks
⚠ Health risk — professional removal recommended. Nest material in vents can trap heat and moisture; droppings accumulate at roosts; mites may affect workers during heavy cleanups.
Native birds can lose cavity access where starlings dominate suitable holes.
Prevention
- Install proper vent caps and screens sized to code.
- Close unused louvres after inspection.
- Reduce open food near buildings at dusk when flocks form.
- Prune dense hedges against buildings that mimic cliff roosts when landscaping allows.
How We Treat European Starlings
We time vent work outside active protected nesting windows when law requires, clear blockages, and install exclusion that still allows appliance exhaust. Roost management may combine netting or structural changes where permitted. Follow-up checks for re-entry at new gaps.

Frequently Asked Questions Q: Are starlings protected?
A: Rules depend on method, season, and jurisdiction—professionals verify before work.
Q: Noisy roost?
A: Large flocks are hard to break without integrated exclusion and food reduction.
Q: Dryer slow?
A: Nest in vent may be the cause—do not run long cycles without airflow check.
Q: Native birds?
A: Cavity nesters like swallows need different protections—ID before closing holes.
Q: Farms?
A: Crop damage programs differ from urban vent work; scope separately.
Q: Acoustic tools?
A: Some are restricted; structural fixes last longer.
Professional Bird Control
European Starling problems in Greater Vancouver require a systematic approach — inspection of the full property, elimination of the root cause, and documented follow-up. Our bird control service covers all of this.
