The effect of social connections on the discovery of multiple hidden food patches in a bird species

Abstract Social foraging is thought to provide the possibility of information transmission between individuals, but this advantage has been proved only in a handful of species and contexts. We investigated how social connections in captive flocks of house sparrows (Passer domesticus) affected the di...
