The note is uttered on the climb of each undulation. Or again 
on prolonged flights the character of the wing beats is as fol- 
lows: Long strokes are made, one, two, three (or one, or one, 
two), with a pause of about one wing beat between each stroke 
wherein the wings are folded. Then come four to six rapid and 
successive strokes which cause a climb. At this time the note, 
‘‘zeet-it’’ is uttered. Then comes a pause of the length of one 
or two beats, with wings folded, causing a drop in elevation. 
These repeat. The bird goes thus: jump, jump, jump, climb 
(call also), drop, jump, jump, jump. 
REPRODUCTION 
Breeding Habitats 
General—Other writers give the following habitats for 
the nestings of the Prairie Horned Lark: On ridges of 
corn (Isley, 1912, Kansas) ; beside hills of corn (Crone, 1889, 
Iowa); meadow-highland and cornfields (Jones in Davie’s 
‘“‘Nest and Eggs of N. A. Birds’’, 1889, Iowa) ; first nest in 
closely cropped pastures, June nests at the hills of corn (Hess, 
1910, Illinois) ; grass-sparse uplands, not prairie (Criddle, 1917, 
Manitoba) ; between the end of ties of the Canadian Pacific 
Railroad (J. F., 1900, Ontario) ; in old meadows (Eifrig, 1911, 
Ottawa) ; on ploughed fields (Soper, 1923, Ontario) ; inside of 
manure heap in a field (Davison, 1885, New York) ; fallow fields, 
prairie tracts, pastures, country roads (Bendire, 1895, general) ; 
early nests in meadows and pastures, later in potato and cab- 
bage fields (G. E. Harris account in Bendire, 1895, New York) ; 
in the oval of a race track in Schenley Park (Brooks, 1908, Pitts- 
burgh, Pennsylvania) ; in the middle of a golf course (Burleigh, 
1923, Pennsylvania) ; dry undulating field, ground more or less 
covered with snow, in bed of hair-cap moss, another in a damp 
meadow (Mouseley, 1916, Stanstead County, Quebec) ; in a sheep 
pasture on top of mountain, very unprotected (Brewster, 1894, 
Massachusetts) ; in an old plowed field too wet to sow (Swain, 
1900, Maine) ; in fields and pastures, sandy barrens (Tufts, letter 
of June 21, 1927, Nova Scotia), in a field of young oats drilled 
into a former corn field (Forbes and Gross, 1922, Illinois). 
That the other subspecies of Otocoris alpestris select the ver- 
dure-denuded opens can also be shown by a few references: dry 
and bare ridges in a wet meadow (Merrill, 1888, 0. a. strigata
