Should vigilance always decrease with group size?

Summary
Results indicate that increased allocation of time to scrounging during search can add to the overall level of vigilance and even counteract the expected decrease in vigilance with group size, but the addition of scrouging was found to have little impact on vigilance while in the food patch.
