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.

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
