One of the most striking features of bird-life is surely its restless activity. This is always apparent, but it attains to a state of almost feverish excitement as the spring advances, and the parental instincts re-awaken. As they gather strength, so they manifest themselves, in outbursts of song—often of exquisite beauty—strange antics, or wonderful evolutions in mid-air.
It is with these last that we are chiefly concerned here. As might be supposed, they present a wide variety in the matter of their form and duration. Black-game furnish an example of a very simple form of courtship flight, but it is associated with curious antics on the ground. And these, it is to be noted, are only to be witnessed soon after sunrise. Two blackcocks will approach one another and stand as if prepared to ward off a very vigorous onslaught; reminding one of two barn-door cockerels. With lowered head and neck they face one another, the beautiful lyrate tail spread fan-wise, and arched so that the curled, outer, feathers touch the ground, while the wings are trailed like those of the turkey-cock. Then one will at last rush forward, and seizing his adversary by the scruff of the neck, will administer a sound beating with his wings. The victor celebrates his triumph by a loud, and most unmusical screech, which has been likened, by that accomplished observer and sportsman-artist, Mr. J. G. Millais, to the call of cats on the house-tops at midnight. But presently a greyhen makes her appearance. Hostilities cease at once, on all sides; and intense excitement prevails amongst the whole assembly—for a large number of cocks will gather together at these sparring matches. Her approach has been observed by a single bird, who, unintentionally, gives the signal by suddenly drawing himself up to a rigid position of attention, till he is sure she is really coming, then he throws himself into the air and flutters up a few feet, uttering at the same time, a peculiar hoarse note of exultation. Immediately all the others follow suit; each seeming to strive to outdo his neighbour in a series of absurd pirouettings. Here we have a “Love-flight,” of exceedingly brief duration, associated with terrestrial combats and frantic prancings.
