from latitude 39° to latitude 41°, in Missouri, Illinois, Iowa, and Ne- 
braska; that during the next two weeks of cold, freezing weather, lit- 
tle, if any, general advance was made, but that enough adventurous 
birds pressed forward to thoroughly confuse the record. During the 
two weeks from Mareh 7 to 21, most of the Robins abandoned winter 
quarters and appeared in new localities, which caused them to be re- 
corded as common throughout the Mississippi Valley south of the par- 
allel of 39°. On the night of March 21 the weather began to moderate 
and the following records of “ firsts” were made during the progress of 
the warm wave which followed: Robins were reported at Chicago, IIl., 
aud Milwaukee, Wis., March 22; Delavan, Wis., and Waukon, Iowa, 
March 23; Stoughton and Leeds Centre, Wis., and Rochester and Excel- 
sior, Minn., March 26. During the last two days of March and the first 
day of April, countless thousands of birds were moving in the Upper 
Mississippi Valley. Among them the Robin was not a small factor, and 
its arrival was noted in northern and northwestern Iowa at Williams- 
town, Sioux City, and Emmetsburgh; at Hastings in eastern Minnesota; 
at Heron Lake in southwestern Minnesota, and at Durand, Luck, New 
Cassel, and Green Bay, Wis. Just north of these places the following 
line of stations reported the first April 3 and 4: Grand View and Huron, 
Dak.; Minneapolis (two observers), Fridley and Elk River, Minn.; and 
Menoksn, Dak., (April 5). A 25-mile ride at White Earth, Minn., found 
the country quite well sprinkled with small flocks, more than two hun- 
dred in all being seen, where all the previous spring not a Robin had 
been found. Two days later the first Robin made its appearance at 
Oak Point, Manitoba, where the species was marked as common, April 
9. These were probably early birds, since the other records for Mani- 
toba are Shell River, April 13; Two Rivers, April 16; and Ossowo, 
April 18, and it was not considered common at any of these places 
before April 20. The whole record from Saint Louis is as follows: 
March 2, first, a summer sojourner at its stand; March 3, small troops 
of transients on the wing; March 5, first female at stand; March 10 
to 14, the bulk of the sammer sojourners arrived at their stands, and 
many transients passed in flocks; March 26 to April 2, the most con- 
spicuous songster; April 2, the bulk of transients had gone north, light- 
colored troops still lingered; April 11 to 16, parties of transients were 
still with us; April 17, last flock seen. 
Col. G. B. Brackett writes from Denmark, Iowa, that about the mid- 
die of April, for the last three years, immense flocks of Robins, num- 
bering many thousands, have come to roost at night in the evergreens 
on his premises. They usually remained about two weeks. 
In the fall of 1885, at Ossowo, Manitoba, the last Robin was seen Octo- 
ber 20; at Elk River, Minn., October 21; River Falls, Wis., October 
29; Lanesboro, Minn., November 3; Milwaukee, Wis., November 11; 
Iowa City, Iowa, October 26; Des Moines, Iowa, October 24; Fernwood, 
Ill, November 21; Fayette, Mo., October 28, and Mount Carmel, Mo.,
