Urban environments support diverse wildlife populations that face unique welfare challenges from human infrastructure, artificial light, noise, and unpredictable food sources.
Urban wildlife welfare exists in a complex relationship between the resources urban environments provide and the hazards they create. Species that successfully adapt to urban living access food resources, shelter, and warmth that can support population growth, but face different welfare stressors than their rural counterparts. Light pollution disrupts the biological clocks of insects, birds, and mammals whose behavior is entrained to natural photoperiod - disrupted migration timing, altered reproduction, and changed predator-prey dynamics result. Traffic noise impairs the acoustic communication that many species depend on for territory defense and mate attraction, requiring behavioral adaptations that carry welfare costs. The interface between humans and urban wildlife creates conflict situations where welfare is often compromised on both sides.
