When Rooks Build
In February, the rooks pay visits to their home-trees, wheeling and squawking round about, and demolishing old nests. On fine February evenings they linger after sunset before setting off to their winter roosting-place. A few, who have begun work on new nests, turn back to the trees undecided, then turn again after their companions. Not until the beginning of March do the rooks seriously set about their building, in mid-March deserting the great roosting-places of winter and mounting guard over their rough nests of sticks.
