"bow and square stern. Both are propelled by a long pole; 
haying a fork lashed' to the end to prevent it sinking 
into the mud bottom. A similiar boat of large size is 
used for ferrying animals across the Desaguadero River. 
The Lake proper does to reach much north of Callipam- 
although the maps show it reaching to Poopo.The ' 
Desaguadero River,which carries the overflow of Lak^^ 
Titicaca into Poop6,has but little current in most parts] 
although at the point where the Arica R.R»crosses it, 
it is narrow and has considerable' fall. In most places 
it widens out over the surrounding land,especially in 
rainy season and forms marshes of considerable area, 
where rushes are abundant and bird life profuse. 
The area of rushes and fres water extends out into 
the lake for several miles in a fan-shaped"delta",and 
in this region,as well as on the river,aquatic birds are 
abundant. Plegadis Ridgwayi ; Colymbus cMlensis;Centroneli 
ma micropteruro ; Larus serranus ; Tachurls rubrigaster : 
Phloecryptus melano-ps schoen .; Pullca cinereus and ' 
Ana s flavirostris oxyptera .also Phalacrocorax sn 
are to be found commonly on the river and in the fresh 
water delts.but as soon as the open lake is reached and 
the water becomes brackish,they,as well as the rushes, 
dissapear. A few miles south of the river delta,the 
water becomes quite salty,but this does not hinder the 
rank growth of the water weeds. In the open lake 
Plamingos were present,literally by the thousands, 
feeding about a mile out from shore in water about arootl 
deep. They were extremely wary and impossible to approaclj 
within gunshot(shotgun),and would very rarely fly over 
near a boat. Lessonia oreas was very abundant .hopping 
about over the water weed searching for insects. Anas 
versicolor puna was more common out in open lake than in 
rushes,as well as the Ruddy Duck. Larus Serranus was 
common everywhere,perhaps is the most abundant bird on 
the Lake. Shore birds were very scarce,but one species 
of A egialitis being at all common on the vast flats along 
the lake shore. The "Stilt" Sandpiper was occasionly seen 
A't this time a few Coots and Flightless Grebes were 
breeding. Three nest of the Gott were taken with partiallj 
incubated sets,and one incomplete set of the Grebe(two) 
with fresh eggs. The eggs of the grebe were covered with] 
the nest material,but the Coot s were not. 
A thorough exploration of the lake with a servicaMel 
boat should yield much interesting information,since we 
knov<? almost nothing about its fauna.

One trip was made to a couple of lakes about ten mil 
southeast of Uncia. Lakes in small valley,with many mmi 
Indians near by and domestic animals,and bird life not 
abundant,except Fulica gigantea .in large numbers,but 
the smaller Coot not present. Anas flavirostris and a 
larger,unidentified Duck .present,also some small Grebes 
probably Colymbus juninens i“s (net secured)
