ham reported a flock of perhaps one hundred feeding on wild 
apples. A boy is stated to have picked up one of these individuals 
while it was feeding. 
Migrant Shrike 
( Lanius ludovicianus migrans ) 
Two were seen July 15, 1917, about two miles north of town. 
One was seen May 15, 1919, along the street car tracks west of 
the Chemistry Building. Other records; 1, May 16, 1920; 1, 
May 22, 1920; 2, May 29, 1920; shrikes nesting, 1920 (J. E. G.). 
The migrant shrike was most certainly a rare bird at Ames for 
a period of several years. However, the discovery of a nest in 
1921, indicates that the species may be establishing itself again. 
That the migrant shrike was formerly a common bird on the 
campus at Ames is revealed by a contribution to the State Register 
by the late Professor F. E. L. Beal while he was connected with 
the college during the period 1879-1883. The following is a 
quotation from that article which is entitled “The Shrike or 
Butcher Bird,” “Several pairs of these birds nest every year 
on the ground of the Agricultural College, and this is the only 
place where we have ever found their nests; nor have we ever 
seen the birds themselves during the summer in any other place. 
It is probable that they are attracted to this locality by the abun- 
dance of evergreens, for with a single exception, the nests have 
been built in those trees.” 
The reasons for the change in the abundance of this bird since 
the days of Beal are a little hard to surmise. Shelter, food and 
protection conditions at Ames appear to have been improved for 
the bird, yet until within the last two years it apparently was 
entirely wanting from its former haunts. 
Audubon’s Warbler 
( Dendroica auduboni auduboni) 
A single questionable record for this western warbler was ob- 
tained May 30, 1917, by Mrs. Ewing and myself. My notes 
made at the time read : “The one individual of Audubon’s 
warbler was seen very plainly for several minutes in shrubbery 
growing along the west bank of Squaw creek. The heavy white 
band on each wing was especially conspicuous. We noticed the 
black lower throat, the yellow on the throat proper and at sides 
of body. We did not see the small yellow patch on top of the 
head, but did not get a view of bird from above.” Since these
