10 Km E of Llao Llao Bytium, Parque Nacional Nahuel Huapi, Pcia de Rio Negro, Argentina
14 May
2530 - !! first condor - spotted at great distance while we were driving along the circuito chico
on the southern return towards Bariloche from Llao Llao. White on wings + strikingly
bulky head visible from distance. Watched it fly out of sight behind a nearby low close hill. It was
not flapping. Black vulture in vicinity.
~10 Km S of Epuyen on road to Cholila, Pcia de Chubut, Argentina
21 May
1045 - 6 condors circling up out of a cloud + mtns, overlooking valley. Visibility too poor to see.
Soon after we spotted them one circled out of sight into clouds, but others remained for ~15 minutes
before building circle + gliding east out of Mtn range. Intermittent flaps. Year's 1st heavy
snowstorm has ended within the last 24 hrs - it may be that they're moving out of what
is now the snow-covered to work.
Cholila Valley, 15 Km N of Cholila by road, Pcia de Chubut, Argentina
Driving along the road we have now seen 9 more condors - all flying low, flapping almost
continuously + all headed E. There seemed to be little sign of any of the birds moving together -
no pairs etc, but individuals were more or less one another. One flying quite high, but
several less than 20m above road. More than 10 Polyborus have been passed in
front of us, moving in the same direction, also apparently solitary individuals
10 Km NE of el Cajon by road, Cholila Valley, Pcia de Chubut, Argentina
1230 - watching 2 condors flying E over us. Suddenly spotted 2 more perched near a
Genanciopsis on a not-too-high cliff face, and a 3rd vulture across a small valley below
through which the road cuts.
~130 Km S of Salta via Rte 6b, Pcia de Salta, Argentina
13 June
total of 25+ condors seen soaring low and along the cliff faces of this river
valley as the road winds up to ~5000' before opening up into the Cafayate valley.
♂, ♀ and immature present.
7 August
we are in the same area as we were 13 June, the Rio Conchus River valley between
Salta and Tijuy. Yesterday I caught a glimpse of only 9 condors along here. The weather
was cloudless and warm. This morning broke with a low cloud cover, obscuring
