quite near to the home of a large dog that 
was not in love with the study of Oology. 
ater in the season (June 28) as 1 
walking by the tree I noticed a Robin 
fly into it with her bill full of dried grass, 
and upon looking up I saw the nest 
built directly on top of the Grosbeak’s. It 
was all completed with the exception of the 
lining. I do not know whether the Gros- 
beak’s eggs were hatched or aot, but think 
quite likely they were. The nest was quite 
a large and strong affair, made of small 
sticks and roots, and furnished quite a good 
foundation for the Robin to commence on. 
Wouid like to know if anybody else has 
ever seen the Robin build in a like position.

A paper was read by W. Otto Emerson 
on the 
“GREAT WAVE OF TANAGERS’’ 
observed at Haywards, Cal., and at other 
points in the State during May last. 
Louisiana 'Tanagers made their appear- 
ance in countless numbers at Haywards, 
between May 12 to 14, frequenting 
cherry orchards, where they did much dam- 
age. They began to move off on the 25, 
all through the hills and canyons, and be 
June 1 only one here and there would by 
seen. ‘hey made their night roosting- 
place in a grove of young live oaks. They 
uttered no notes whatever. Two men were 
kept busy shooting them. All the ammu- 
nition used seemed not to decrease the 
numbers which came day after day. Dead 
Tanagers lay about by the hundreds, and 
were food for the cats. Perhaps a thousand 
of the birds were slaughtered. 
‘‘My notes for the last 15 years record 
this species here but twice—a female seen 
May 28, 1880, and another observed May 
21, 1883. Almost all the birds seen this 
year were males. 
‘““Mr. Horace A. Gaylard writes me that 
at Pasadena they were seen singly from 
April 23 to May 1. From this date to 
May 5 their number were greatly in- 
creased, then for about 10 days, until May 
16, the great wave of migration was at 
its height. By May 26 the last of the 
birds had left the valley. What caused 
this great wave of Tanagers to move so 
regularly together through the State north- 
ward can hardly be known positively. It 
may have been caused by the late cold spell 
occurring in California, April 15, and 
meeting them on their way from their win- 
ter quarters in Central America, inducing 
them to move together in large companies 
where food was plenty and the weather 
milder.’’
