Ranthodon (cont.) Nov.30-Dec.1. arriving Estancia San Ramon at 9:30 p.m., Warm, no wind, moon came up about midnight. Heard barn owl a several times during night, saw one at 9:49. 6 horses near our observing area. They partly hazy all night. We had the NVGs on we spotted 4 Ranthodon during the night. #1 We picked up at 9:53 out in the turf, which was as early as you could get them to locate. Followed him until 12:25 when he went down a hole. Then we went to bed and got up at 3:45 (3/4 hour) and spotted 3 more Ranthodon (see below), the last one of which stayed out until 5:54, which was light enough to follow him until 11:00. Saw one other R while following it. Hence a total of 5 sightings in the 100 x 140 yd² area covered in our observations. Probably 4 or 5 individuals. See map next page. #1. Spotted soon after dark at 9:53, as early as we could be effectively and kept him in sight until he went down a hole in the turf at 12:25 = 2 hrs 32 min. The hole where he disappeared was 30 yards from where we first saw him. Another R passed within 2 m of him at 11:04 at a place 50 yards from the hole into which he disappeared. During the 2 1/2 hour, he spent most of it eating or "searching", presumably for food items. Occasionally he would settle in one spot for 5 minutes or more, poking into the grass for food, and chewing. He scratched his fur 3 or 4 times, worked his face 2 or 3 times, but no grooming sessions lasting more than a few
