Bottom Line: Use of novel food sources was faster in urban habitats and the presence of other feeders reduced the time until a new feeder was located.Urbanization may be associated with behavioural skills, technical innovations and neophilia resulting in faster discovery of new food sources.This process is accelerated by the experience of feeder use in the vicinity, with a strong modifying effect of the number of domestic cats.

ABSTRACT
Adapting to exploit new food sources may be essential, particularly in winter, when the impact of food limitation on survival of individuals is critical. One of the most important additional sources of food for birds in human settlements is birdfeeders. At a large spatial scale, we experimentally provided birdfeeders with four different kinds of food to analyze exploitation and use of a novel food supply provided by humans. Nine species started foraging at the new birdfeeders. The species that exploited the new feeders the fastest was the great tit. Use of novel food sources was faster in urban habitats and the presence of other feeders reduced the time until a new feeder was located. Urbanization may be associated with behavioural skills, technical innovations and neophilia resulting in faster discovery of new food sources. This process is accelerated by the experience of feeder use in the vicinity, with a strong modifying effect of the number of domestic cats.

f2: Differences in average time taken for birds to use a novel source of food (expressed in minutes) on y-axis, related to the presence and number of cats (x-axis) in the study area.

Mentions: For all species in GAMM models, the urban environment was correlated with a decrease in time spent using the new source of food. The number of bird feeding stations and species richness of other birds that were seedeaters was positively correlated with the speed of use of the new food source, while the presence of cats was a cause of slower use of feeders (Table 1, Fig. 2).
