THE CONDOR 
Vol. XVI 
standing rushes about six inches above the water. Some gray down-feathers, 
larger in size, if anything, than those of the Mallard, were in the nest, but the 
bird had evidently only started to provide the lining. Additional evidence of 
the well-known fact that Redheads and Ruddies on occasion lay their eggs in 
other ducks’ nests is thus afforded. 
Querquedula cyanoptera. Cinnamon Teal. A few Cinnamon Teal were 
seen at the head of Tule Lake. A female was flushed from her nest in the 
middle of a muddy peninsula on June 1. The nest was a depression lined with 
broken stems of tules mixed with a quantity of down, and was poorly con- 
cealed in a sparse growth of weeds. It contained nine eggs. 
Erismatura jamaicensis. Ruddy Duck. About eight individual Ruddies 
Avere seen during one morning’s excursion. A new nest, discovered in a clump 
of tules where a pair of Ruddies Avas seen, Avas thought to pertain to this spe- 
cies. Evidence as to breeding Avas obtained through the finding of the one 
egg in the nest of a Redhead, as described above (see fig. 68). 
Shore-birds. — Although no nests Avere found, the actions of Avocets, Stilts 
and Killdeer showed that they Avere nesting in the vicinity. Avocets were 
more abundant than Stilts in this locality. All shore-birds, however, were 
found in less numbers than at Los Banos. 
LOAVER KLAMATH LAKE, OREGON AND CALIFORNIA 
Our camp on White Lake Avas situated in an old store building at the for- 
mer tOAvn-site of White Lake. This situation Avas our headquarters from June 
3 to 6, and made possible explorations along the Avestern shore of Lower Kla- 
math Lake as Avell as on White Lake, in both Oregon and California. On the 
Avest side of the lake Ave camped until June 9 on Taylor’s ranch at the mouth 
of WilloAv Creek, near the toAvn-site of BroAvnell, Siskiyou County, California. 
From this point Ave made a launch trip eight miles north to Bird Island and 
Sheepie Lake, but we spent most of our time on the freshwater marshes at the 
mouth of WilloAV and CottonAvood creeks. 
The eastern and Avestern shores of LoAver Klamath Lake are very differ- 
ent from one another in character. The eastern is lined Avith a dense strip of 
tules that extends into the lake a distance of five or six miles. Ducks were 
seen flying about over these tule beds and no doubt nest in them, but we found 
it impossible to search for nests. It Avas dangerous to Avade and the tules Avere 
too thick to permit of using a boat. Judging from experience elscAAdiere, ducks 
prefer localities Avhere there are frequent open patches of water rather than 
unbroken stretches of tule groAvth. A small lake near the eastern shore of 
Lower Klamath, knoAvn as White Lake, is famed as a favorite haunt for ducks 
during the migrations. Along its eastern shore there are excellent nesting 
grounds for the ducks Avhich prefer a growth of tules Avith open Avater adja- 
cent. As the hills come doAvn to the lake on the southern shore of LoAver Kla- 
math, the Avater is too deep for an extensive groAvth of tules. The best nesting 
grounds Avhich we found were on the Avestern side of the lake, in California, 
Avhere the small streams entering the lake form extensive marshes. The marshes 
at the mouths of CottonAvood and WilloAv creeks are due to artificial inter- 
ference. Excellent conditions are said to obtain at the i mouth of Sheepie 
Creek also. Only a narrow strip of tules fringes the lake on this side except in 
the vicinity of Bird Island AA^here there are many tule-covered islands separated 
by channels of open Avater. 
Anas platyrhynchos. Mallard. The Mallard is apparently the common-
