Motherwatch (cont.) This bird after a few minutes closed it until it flew squealing downhill. While it was flying she ran after it for 15 or 20 yds (have seen others do this also). Then she walked slowly down its ridge, still calling loudly, perhaps 80 or 90 yds from nest. At 4:45 the red P left the nest stealthily and made his way across and downhill along his usual route (but also in this case toward the calling Q). In 5 to 10 minutes after he had disappeared fully, his crossing again, he joined the Q who no longer called. Intense courting followed: when she approached him, he would fluff his feathers and stand his ground either facing her or look toward her. She would respond by darting a few feet or yards away. Then he would stop posturing and fed away, whereupon she would follow and approach, he would posture etc. Her dartings were conspicuous. During one prolonged posturing there was fluttering + squeaking as I thought that the other did also. Both paired for about 1 minute after a few minutes both disappeared into tall grass behind rock out I saw him no more. After about 5 minutes, however, a bird (presumably the P) emerged from the grass and walked fairly rapidly without calling toward the nest ridge. Just her in gully but a few minutes later he deep-voiced bird (probably same one) appeared on the ridge opposite (close) to nest, calling occasionally. Shortly after calling came from down terms where she had come.
