feed upon the grain. Ur. Shepard’s place is on the edge of 
the irrigated district, separated from the desert on the Y;est 
onlv hv the canal. Loves of both species were nesting in the 
mosquites bordering the canal. Just across the road bordering 
the v^jhepard x^ls^ce on the north v/ere EG acres of v/heat- stubble 
which seemed to be the main attraction for the bird^. In one 
comer of this field was a stack of cut, but un thro sad, Y/heat 
upon which the birds fed continually. Hundreds of doves passed 
all day long between the stubble-field and the trees and bushes 
along the raod and canal, across the road from the stubble- 
field Ur. dhepard had 70 adres of uncut wheat which also came 
in for a large share of the doves’ attention. 
Because of tlie continual movement it was extremely difficult 
to estimate the number of birds in the fields, but a conseiwative 
guess v;ould place the largest flock seen at one time in the 
stubble-field at 1,000. About 200 ware flushed at once from 
the standing wheat, and as many as 50 were seen feeding to- 
gether on the stack. Ualopelia apjparently more numerous than 
Henaidura . 
Barley seemed to have no attraction for the birds. 
Control. 
To determine the efficacy of poison, 15 qits. of 1 to 20 
alkaloid-wheat were distributed along fence row, in wheat 
stubble, and under bushes outside of the canal at 11:30 A. U. 
June 7th- By 10 A.M. next day this produced 186 Melopelia 
and 145 Zenaidura . June 8th 20 qts. of 1 to 40 alkaloid- 
wheat were distributed broadcase in stubble. By 7 ^i.M. 
June 9th the combined 35 qts- of poison x-^^’oduced 299 Melopelia 
and 356 Zenaidura — not counting numerous spots of feathers 
left by some 20 bu^^aards feeding over the fields. As much 
jpoisoned grain was still on the ground at 7 A.M. , and no 
reduction in the nwnber of live birds could be noticed with 
the eye, it is quite reasonable to estimate an ultimate kill 
of 1,000 birds from the 35 qts- of poison-
