Unintentional food resources in urban areas(street litter,food leftovers,overflowing trash bins)are dietary components of some urban-exploiter bird *** this study,we report on 13 bird species in six southern Finnish cities using urban trash bins and describe differences in their activity when provided with food resources(i.e.,bait)in different bin *** used generalized linear models(GLM)and classification and regression trees(CART)to test for associations between environmental variables and bird activity at the *** activity at the binscapes significantly differed among all cities and among types of bins and was significantly higher after placing bait in all *** with the largest opening had more activity as opposed to those with smaller openings or *** and gulls had the highest activity,with corvids usually being present before the bait was placed and gulls increasing their activity *** differences show that trash bin foraging is highly malleable and thus susceptible to management preventing its *** waste management measures could aid in reducing the number of species close to bins and their surroundings,benefiting both bird and human health.
