SP Myers 1973 Journal Rio Grande to Ushuaia, Tierra del Fuego, Argentina 2 November cont. e.g. Lago Fagnano, the Beagle Channel, etc., and smaller valleys running N.S. which, appear due to the glacial formation of the E-W-, are largely hanging valleys above the major E-W series. The weather changes while passing from one of the E-W axis another, and within 15 min-30 min it can become quite stormy within a given E-W valley. Weather came from the W. Arrived in Ushuaia in mid afternoon. Steamer ducks, Macronectes, [illegible] brown at [illegible], cormorants (white necked species), kelp gull, skun, a Magellanic penguin, kelp geese, and more in Bay. We went on toward Lapataia to camp for night. At La Esmeralda another white [illegible] duck was perched in the trees by the road. Not at all spooky. At mussels from Channel for dinner. Lapataia, Tierra del Fuego, Argentina 3 November We camped on a side road off the main road between Parque Nacional del Tierra del Fuego (Lapataia), by a river (Rio Pipo (?)) which the road had been paralleling after leaving Ushuaia. Dense Wet foliage, except where logged to along lower stretch of river. However, the density is not so great as to be impassable. We walked upstream for ~1 Km from camp in order to fish (no luck). Pair of ashy-headed gase flew past us on the river. No torrent ducks. Many house wrens Watched 3 Dark Faced Ground tyrants: at first five were only two birds foraging on ground a third flew in. One of the original pair then began displaying—approached intruder, raised one or both wings to a point (above body) at 45° from horizontal, the original pair followed" the intruder upstream until out of sight (30 yds), repeating the display. It was impossible to keep the bride straight, so one or both of the pair may have been displaying, although I had the definite impression that only one was. Also buff-necked ibis, chermango, chestnut swallows, Zonotrichia. [illegible] Lapataia: After breaking camp we went to Lapataia and out to Bahia Lapataia; Literally the end of the road. 3 species of cormorant (found a nest with eggs), kelp, and ashy-headed. Both species of steamer duck. Rufous backed negritos, or cinclodes sp., great gull, a large flock of buff-necked ibis. House wrens. Back toward the Hosteria watched an immature Nectornyx nycticorax fishing. Overhead flew was almost always a Black cheeked Buzzard eagle. 2 Bare-chested Sandpipers!! on river bank at Hosteria.
