Information gathering updating information
Contrary to this, if the IGS hypothesis is true, fast explorers are more active and strategically choose to look for information in novel areas more than slow explorers, who instead prefer to return to already visited patches to sample. We also wanted to see if any of the behaviors in the information experiment were influenced by the current state of individuals, and therefore also tested all behavioral responses against body condition ( Peig and Green 2009 ).Consequently, for the IGS hypothesis, we also predict that information gathering and BF are related in an opposite way from the BF hypothesis, with fast explorers moving to new profitable patches sooner than slow explorers. With this, we hoped to capture possible differences in energetic state between individuals as body condition could potentially influence foraging behavior, independently of personality traits ( David et al. Following Dall and Johnstone (2002) , we predicted a positive correlation between body condition and sampling as individuals in a good condition can afford to sample uncertain resources more.However, it will also decrease the possibility of encountering better resources and gaining knowledge of resources, which can be used as buffers if known resources are failing. Individuals can thus adapt their IGSs to try to optimize energy input according to state.
We also examined if these relationships can be explained by an alternative hypothesis where individuals are expected to express variation in behavioral flexibility (BF).A study of blue tits ( ) also found a positive correlation between feeder discovery in the wild and a similar measure of exploration behavior in captivity ( Herborn et al.2010 ), reinforcing the idea that gathering information may be personality related.A different trait, problem-solving ability, has also been linked with foraging home-range sizes ( Cole et al.2012 ), suggesting that this trait is predictive of information-gathering style, where problem solvers are able to find more detailed information on resources in a specific area than nonproblem solvers, who have to move over a larger area to gather the same amount of information.Individuals that gather less detailed information about their proximate environment may cover larger areas to seek information in response to environmental challenges, compared with individuals that gather more detailed information ( Kramer and Mc Laughlin 2001 ; Sih and Del Giudice 2012 ).
