They have also fierce combats now and then with an invading hawk, and will drive him off from their territories by a posse comitatus.  They are also extremely tenacious of their domains, and will suffer no other bird to inhabit the grove or its vicinity.  There was a very ancient and respectable old bachelor owl that had long had his lodgings in a corner of the grove, but has been fairly ejected by the rooks, and has retired, disgusted with the world, to a neighbouring wood, where he leads the life of a hermit, and makes nightly complaints of his ill-treatment.

The hootings of this unhappy gentleman may generally be heard in the still evenings, when the rooks are all at rest; and I have often listened to them of a moonlight night with a kind of mysterious gratification.  This gray-bearded misanthrope of course is highly respected by the squire, but the servants have superstitious notions about him; and it would be difficult to get the dairymaid to venture after dark near to the wood which he inhabits.

Besides the private quarrels of the rooks, there are other misfortunes to which they are liable, and which often bring distress into the most respectable families of the rookery.  Having the true baronial spirit of the good old feudal times, they are apt now and then to issue forth from their castles on a foray, and to lay the plebeian fields of the neighbouring country under contribution; in the course of which chivalrous expeditions they now and then get a shot from the rusty artillery of some refractory farmer.  Occasionally, too, while they are quietly taking the air beyond the park boundaries, they have the incaution to come within the reach of the truant bowmen of Slingsby’s school, and receive a flight shot from some unlucky urchin’s arrow.  In such case the wounded adventurer will sometimes have just strength enough to bring himself home, and giving up the ghost at the rookery, will hang dangling “all abroad” on a bough like a thief on a gibbet; an awful warning to his friends, and an object of great commiseration to the squire.  But, maugre all these untoward incidents, the rooks have, upon the whole, a happy holiday life of it.  When their young are reared, and fairly launched upon their native element, the air, the cares of the old folks seem over, and they resume all their aristocratical dignity and idleness.  I have envied them the enjoyment which they appear to have in their ethereal heights, sporting with clamorous exultation about their lofty bowers; sometimes hovering over them, sometimes partially alighting upon the topmost branches, and there balancing with outstretched wings, and swinging in the breeze.  Sometimes they seem to take a fashionable drive to the church, and amuse themselves by circling in airy rings about its spire:  at other times a mere garrison is left at home to mount guard in their stronghold at the grove, while the rest roam abroad to enjoy the fine
