The Black and vvTiite \?oodpecker was fpund only, in. the 
thorn scruD. i^o holes were seen an 3 n(Vhere vmich might 
Belong to it,except a few in the Giant Cactus. I strong¬ 
ly suspect that it nests there, it was never seen around 
the ?/illow or Molle trees,while the thorn acruh is t 
all too small for it to nest in,and Besides is extr^rely 
hard,even when dry. 
Pinca Salo i , 
This is another section of Oploca,in another valley 
to the east,which opens into the Oploca valley about 
half way down to Tupiza. The valley is wider and contain? 
more good land than Oploca,But there is less water. 
The old hacienda Buildings are perhaps 500 feet higher tl 
than at Oploca. It is an hour’s run By auto from one 
place to,the other. The Salo valley is also enclosed 
for the most part By high,eroded Bluffs of sandstone 
and conglomerate. There is a small pond,with several 
acres of marsh just Below the hacienda Buildings where 
we took Anas soinicauda and Anas cristata . The small 
Yellow Billed ,Ducke here also in small numbers. In the 
marsh were several Pulica gigantea,about 25 Pulica 
ardesiaca and about the same number or more of the 
red shielded Gallinule. At edges of marsh were quite a 
number of Anthus sp. and a few Snipe. 
For the most part the land Birds were the same,But 
Being higher up there were fewer species. 
semiBadius was common,and here we took five specimerai^ 
of Upucerthia ruficauda,hitherto very rare. 
There is much thorn Bush here,trees quite large,But 
fewer Molle. Less cultivated land and more pastures.

Collecting v/as done here from July July 8 to 19 inclusiv 
The nights are invariably cold,usually a heavy frost 
falling. The temperature inside the enclosed patio 
usually dropping to 34 degrees P. at night. The days 
are usually cloudless and warm,though not oppresively 
so,and inside a house it is always cool during the day. 
Most of the time there was no wind,But on July 19 and 
20 there was strong winds,mostly in gusts. It seems that 
in August the winds are Bad. The only night here when 
there was wind(the 19th.) was much warmer,and the next d 
day seemed warmer. The wrind was from the north. 
Cun rises about 7.15 and sets about 5 P.M. Were 
able to work without artificial light until 6 P.M. 
The Thorn trees were mostly with green leaves,also the 
Molle trees. The Willov/s were mostly with leaves,But 
yellowish,and sometimes nearly Bare". Peach and apple 
without leaf,also Mogal. A few Peach Blooming Jul.18
