Question 6

Most bird species that form flocks show a negative relationship between flock size and individual vigilance (i.e. ,the larger the flock,the less often an individual lifts its head to scan the surrounding environment) .However,some bird species have shown a positive relationship between flock size and individual vigilance.The positive relationship is particularly strong when flocks are space-constrained,such as in small ponds or fields.What is the most likely explanation for this?
