Callipampa (con.) 
Considerable time and effort was spent on checking the 
land birds,I spending most of my time in that work, 
except for one day on the Desaguadero River and one 
day on the lake. Y/hen I >was here in 1936 I was just re< 
covering ±sl from a bad injury to my right foot which 
happened in Catavi,and I could not cover much ground 
in my shooting trips. This year I covered thoroughly 
the pampas and mountains to the east. 
Very little change was found in the species of 
land birds present. The only species taken in 1936 
which were not taken'or seen in 1938 were the following 
'Gallinago paraguayae andina;Upucerthia dumetoria 
hypoleuca;Muscisaxicola capistrata; M.frontalis; 
Phyrgilus erythronotus;Spinus magellanicus bolivianus. 
The two Muscisaxicola are undoubtably migrants from 
the South,as proved from absence of all localities 
this year(in the summer). Phrygilus erythronotus 
may have been overlooked,as it was scarce in 1936. 
The additional species secured in 1938 were: 
Cinclodes a.atacamensis; Sicalis uropygialis;Metriopelis| 
aymara; Chestnut backed Hawk; Accipiter(?) sp.; 
Geositta tenuirostris; 
Pygochelidon cyanoleyca patagonica;Anthus furcatus 
brevirostris;Geositta cunicularia titicacae;Ochthoeca 
oenanthoides;Andean Avocet; Himantopus(?) _? 
Nycticbrax nycticorax cyanocephalus;Idiospiza inornata; 
Of course'in 1936(June)there were no*Forth American 
Shorebirds atall on the lake ,except a few Lesser 
Yellowlegs which for some reason had not returned 
north with the spring migration,injured or sterile bird^ 
Vi 1 oca ( Araca Mine ) (13,800 feet*) 
Prom Callipampa we went to Oruro,where three days we 
were spent,arranging matters to go to Viloca,separating 
and repacking supplies and specimens and a day spent 
with Fran.’Steinbach,who came up from Cochabamba to meet 
me in Oruro to 'exchange some birds from his collection 
for an old shotgun and some extra supplies which I had. 
We reached Oruro on Tuesday night and left Saturday 
morning 'for Eucalyptus by train (60 kilometers to north] 
from where we continued in truck to Viloca,a distance 
of 142 kilometers,high up in the eastern cordillers 
of the Andes,just south west across the valley of the 
Rio La Paz from the famous peak Illimani. 
At one point on the road we crossed a divide 
at 5200 meters altitude,while the mine camp is at 
4700 meters,and mine workings extend much higher.
