the first, which had been seen there February 27. February 28 they 
were seen also at Mount Carmel and Fayette, Mo. The next warm 
wave (March 3) brought them to Paris and Griggsville, Ill, and the 
next day they reached Ferry, Iowa, and Aledo, Ill. March 9 was a 
great day for the movement of Bluebirds in southeastern Iowa, where’ 
they were reported at Morning Sun, Richmond, and Coralville, though 
they had been seen the day before at Des Moines and Newton, in the 
center of the State. They were seen also March 9, at Peoria, Ill., but 
the real movement in this part of Illinois took place March 14, at which 
date they reached Tampico (both observers), Fernwood, and Chicago, 
and also Clinton, Wis. At this time the van rested at latitude 44° 30’, 
in Illinois and Iowa, remaining there during more than a week of freez- 
ing weather, until March 26, when, according to the testimony of the 
reports, they spread to Williamstown, Iowa; Stoughton, Milwaukee, 
Leeds Center, and New Cassel, Wis.; and Lake City and Excelsior, 
Minn. Hardly a note was made during the next five days, and then a 
strong movement was noted. Mareh 31 they reached Ripon, Wis., and 
Hastings, Minneapolis (two observers), and Saint Cloud, Mivn. Further 
advance in eastern Wisconsin was strangely delayed, and the three 
stations in the vicinity of Green Bay did not report a Bluebird until the 
last week in April. In the western part of the district migration was 
still slower. The first was reported from Linwood, Nebr., April 27; 
Huron, Dak., May 16, and Oak Point, Manitoba, May 26, thus showing 
the peculiarity already noted in the spring of 1884, namely, that the 
Bluebird, after traveling in company with Robins, Blackbirds, Killdeers, 
Ducks, and Geese from its winter home to latitude 44°, then drops be- 
hindhand and occupies a month longer than they in performing the rest 
of its journey. 
In the fall of 1885 the last Bluebird was reported from Elk River, 
Minn., October 16; from River Falls, Wis., October 13; Lanesboro, 
Minon., October 23; Milwaukee, Wis., October 10; Grinnell, Iowa, No- 
vember 4; Fernwood, Ill., October 10; Des Moines, Iowa, October 24: 
Iowa City, Iowa, October 24, and Mount Carmel, Mo., October 30 
Three troops of Bluebirds were seen going south at Saint Louis, Mo., 
September 9, and a flock of over 300, October 7. 
767. Sialia mexicana Swains. [23.] Western Bluebird. 
A straggler from the Rocky Mountain region. In Concho County, 
Tex., it is a rare winter visitor (Lloyd). At Boerne, Tex., Mr. Nathan 
Clifford Brown shot two specimens, each from a small flock, January 
28 and March 1, 1883 (The Auk, Vol. I, 1884, p. 121). Stragglers have 
been recorded from Minnesota and Iowa. 
768. Sialia arctica (Swains.). [24.] Rocky Mountain Bluebird. 
This species is seldom found in the Mississippi district except on the 
high plains of the West and Southwest. It breeds in the mountains, 
from latitude 36° northward far into British America, and winters from
