JP Myers 1993 Journal 60 24 October cntd Punta Norte to Caleta Valdez, Peninsula Valdez, Provincia Chubut, Argentina plus one young) passed by as headed north less than 50 yd offshore (just on the other side of the breakers - it was very unimpressive). I do not know how deep the water is at that point, Fick was high. As I was photographing near camp a flock of 30 or so White rumps landed at the on the pebbles at the top of the tidal edge. A solitary white-rump was also seen with a solitary (Chandriiform) within a few feet of a bull elephant seal. Also heard one Band's flyover, also solitary. Driving south toward Caleta Valdez we saw oceidnipes (Thinorius ruminiciorum) along the road, beginning less than 500 yd from where we camped. They fly like sandpipers, which was how I recognized them, but their ground movements, are very different. We also saw a minimum of 8 flocks of (valky lesser rhea, all accompanied by a solitary adult, plus 20-30 adult rhea occurring singly or in small groups of up to five individuals. The largest group of chicks had 20+ individuals - they are very hard to count as they run through the scrub; the smallest ~5. Each flock was com- posed of individuals of fairly uniform size, but there was variation between flocks, with the smallest chicks being less than 1.5' (the adult had to wait for them while fleeing from us) and the largest being perhaps 3' (running well). 10-15 Guanaco spread thinly along the road, especially toward Caleta Valdez. A flock of ~35 Golden Plovers at the head of the calata. At this point we suffered a flat tire, and persisting only one spare, we opted to head quickly to Puerto Piramide. Golfo San Jose, 16 Km N by road from the intersection of PicĂșn Pito #2 and #3, Peninsula Valdez, Provincia Chubut, Argentina After another flat tire, we decided to remain at the site where we had camped the night of Oct. 22. We arrived at 1900 hrs, and found that the flock of 400+ LAR were again roosting near the campsite. I disturbed them in order to greet nets. But that evening, just as twilight was fading to night levels, I walked along the beach and found that the birds were spread out along the interface between Salicorns and beach. Nothing was therefore unsuccessful. The question remains as to whether or not they were there because I had disturbed them earlier, or whether movement to this area after dusk was typical. Recall that
