as before. It is a constant little run of hops, a pause, and then another little run of hops, each bird following the other about in turn, the distance between them being, as a rule, from two or three feet to five or six paces.
"3.10. — Another little fly up into the air, followed by the frenzied dance on descending. Then the two come together in the mouth of a rabbit-burrow, fly at each other as before, separate again almost immediately, and continue their hopping over the warren, the one still dogging the other.
"3.30. — The two fly at each other as though to fight ; but, again, just as they seem about to meet, they avoid, and quicker than the eye can follow they are a yard or so apart. One of them then dances violently from one depression of the soil to another, arching the space between the two ; at the end of it he fans out the tail and stands looking defiantly at his rival, who fans his and returns the glance, then makes a little run towards him, sweeping the ground with it. Instead of fighting, however, which both the champions seem to be chary of, one of them again runs into a hollow — this time a very shallow one — and begins to dance, but in a manner slightly different. He now hardly rises from the ground, over which he seems more to spin in a strange sort of way than to fly — to buzz, as it were — in a confined area, and with a tendency to go round and round. Having done this a little, he runs quickly from the hollow, plucks a few little bits of grass, returns with them into it, drops them there, comes out again,
- Very like the action of the nightjar when disturbed with the young chicks.
