“Twice already I have mentioned that strayed chicks fall a prey to "hooligan" cocks. These hang about the rookery often in little bands. At the beginning of the season there are very few of them, but later they increase greatly, do much damage, and cause a great deal of annoyance to the peaceful inhabitants. The few to be found at first probably are cocks who have not succeeded in finding mates, and consequently are "at a loose end." Later on, as their numbers are so greatly increased, they must be widowers, whose mates have lost their lives in one way or another.
Many of the colonies, especially those nearer the water, are plagued by little knots of
"hooligans," who hang about their outskirts, and should a chick go astray it stands a good chance of losing its life at their hands. The crimes which they commit are such as to find no place in this book, but it is interesting indeed to note that, when nature intends them to find employment, these birds, like men degenerate in idleness.”
