5 P. PEARSON 1952 Mothopasta (cont) minutes he walked off rather determinedly (I thought perhaps he had seen me) and disappeared in a tall grass patch about 40 yards away. A half-minute later a perdix flew out of this patch, landed 20 yards away, walked quickly uphill and out of sight. Perhaps 10 seconds after this one flew, a second flew out of the patch and landed not far from where the original bird had been chirking. Perhaps a ? chasing off another ??
