Rio Grande to Ushuaia, Tierra del Fuego, Argentina
1 November
cont'd
1700 left Rio Grande and headed south along the main road to Ushuaia. Stopped at Punta
Maria, ~28km S of Rio Grande key road we found a Zonibryzoides nest (+ photographed
it and the bird). Several other nests seen in the vicinity. M.R. on Jell had told us there
were several nesting birds by the road here. 11 preps seem flying between R.G. and P. Maria.
Preps also landing or turning-like vegetation while the Zonibryzoides are nesting. Between R.G.
and Viamonte the road runs along the coast except for a long initial detour inland in order to
cross the Rio Grande. Upland Geese were everywhere. S of Diamante we entered into deciduous
Nothofagus and headed SW inland toward Lago Fagnano. 2 Gallinago gallinago, the 2nd in
a meandering stream meadow in the midst of Nothofagus. There also were Tucelo felixlandii
and a Fiery-eyed dicton (an incredible rideye). We camped on a side road heading west
toward the N side of Lago Fagnano. 3 dominant birds around camp - Chilean swallows, behaving
as if they were resting in the Nothofagus, upland geese (unavoidable), and Buff-necked ibis-
which flew over calling frequently. In the morning of the 2nd we drove on South toward
Ushuaia, stopping briefly at L. Fagnano because I saw 30-40 shrews on the water. Sp.
unidentified - they were dark bellied, with no visible white, either underclim or on bill.
Secondary parts appeared somewhat lighter brown than the rest of the body. Very slender and long
wings. Tail looked like that of a sooty shearwater, perhaps a bit trigger. At the lake there was a very
strong wind blowing out of the west toward us. The hide were at the E end, visible from a cliff
over the lake ~10 km W by road from the ACA Hootenia. At 6: Further along the road, but still
alongside the lake we got an excellent view of a white-throated caracara; it was with a Caracara
in the forested area at the sides of the road. At Lago Sancudni we stopped to photograph a
major pent bag by the road - an amazing number of house crows in the surrounding forest and
the dead trees in the bag. The road goes over a pass to the SE of this lake, reaching ~1500'. At
this elevation the Nothofagus becomes sparse and gravelly; just above the road here is timber low.
In a few places the road reaches meadows which are continuous with the alpine vegetation.
The weather has been temporarily cold + spatially extraordinarily variable over a very small scale,
the inland mountains have two dominant features - very long and deep E-W valleys-
