latitude 44° 30’, May 14. West of the Mississippi the record began at 
Reeds, Mo., latitude 37° 08’, April 8, and was carried on by arrivals at 
latitude 38° 45’ in Missouri, and latitude 39° 12’ in Kansas, April 17; 
at latitude 41°14’ in Iowa, April 23; latitude 419 38’ in Iowa, April 25; 
latitude 44° 47’ in Minnesota, May 2; and May 3, at latitude 45° 05’ and 
45° 25’ in Minnesota. May 10, it was reported at Frazee City, Minn., 
(latitude 46°33’), by Miss Gertrude M. Lewis; and another early date 
came trom Oak Point, Manitoba (latitude 50°30’), where it was seen 
May 8, by Mr. A. T. Small. The records on this species cover a stretch 
of country about 1,400 miles in length, and the average rate of migra- 
tion (whether taken from the records east or from those west of the 
Mississippi River) is twenty. miles a day. The rarity of the Whippoor- 
will over the region of the Great Plains is seen from the fact that not a 
single record was received from Nebraska or Dakota. 
In the fall of 1884 the last Whippoorwill was seen at Elk River, 
Minn., September 23; at Lanesboro, Minn., September 22; and at 
Grinnell, Iowa, October 10. 
The notes on this species for the spring of 1885 can be arranged with 
ease, since nearly all of them belong to one wave. The first records 
were: Mason, Tex., March 27; Gainesville, Tex., April 6; Reeds, Mo., 
April 12. The wonderful warm wave which occurred in the Mississippi 
Valley from April 19 to 24 induced the Whippoorwill to migrate over 
an immense stretch of country. During these days it was noted from 
Mount Carmel, Mo.; Peoria, Aledo, and Chicago, Il].; Morning Sun, 
Ferry, Coralville, lowa City, Newton, Grinnell, Ames, La Porte City, - 
Williamstown, and Waukon, Iowa; Leeds Centre, Durand, River Falls, 
New Richmond, and Luck, Wis.; and Elk River, Minn. After suck an 
extraordinary wave as the above it is natural that further advance 
would be long delayed, and no report came from any station north of 
Elk River, Minn., until the extreme limit of the northern range was 
reached, at Oak Point, Manitoba, May 12. It was noticed in 1884 that 
the Whippoorwill was not reported from Nebraska and Dakota. In 
1885 no reports come from these States nor from Kansas. In the fall 
of 1885 the last was seen at Mount Carmel, Mo., September 20. 
418. Phaleznoptilus nuttalli (Aud.). [355.] Poor-will. 
The scarcity of the preceding species on the Plains has been men- 
tioned. Its place there is taken by the present species, which is a rather 
common summer resident in Texas, Kansas, Nebraska, and Dakota, pass- 
ing eastward, even to Grinnell, Iowa, where an accidental visitant was 
taken in 1880. In southeastern Dakota Dr. Agersborg recorded it as 
common, but gave no date for its arrival. In the spring of 1884 it was 
seen at Mason, Texas, April 8, and at Manhattan, Kans., May 6. It 
proceeds north to about latitude 48°, and winters near our southern 
border. . 
In the spring of 1885 the first Poor-will was noted at San Angelo, 
Tex., March 26. It arrived at Manhattan, Kans., April 15, but the
