meadow in Swope Park, where it sometimes breeds, and along 
the Missouri Pacific right-of-way in the upper Blue Valley, 
where there is much red clover. 
The weak, high-pitched, insect-like notes of this little skulker 
more often attract attention to it than an actual sight of the 
bird. 
AMMODRAMUS SAVANNARUM BIMACULATUS Swainson. Western 
Grasshopper Sparrow. 
Rare migrant. 
The study of a more extensive series of Grasshopper Sparrow 
specimens than is yet available will be necessary in order to 
determine the local abundance of the western form. Only one 
specimen (Teachenor, Lawrence, Oct. 14, 716) has been exam- 
ined. Further collecting may establish this subspecies as a 
regular migrant in this region. 
PASSERHERBULUS HENSLOWI HENSLOWI (Audubon). Henslow 's 
arrow. 
Not uncommon migrant; rather uncommon summer resident. 
The Henslow’s Sparrow arrives usually during early April 
(March 28, 1916, earliest) and leaves during October. It nests 
about marshy places and wet meadows and in damp grassy 
places. It has been frequently observed in the alfalfa field in 
Swope Park, on the Armour stock farm, about Lake City and 
has been found nesting near Independence. It is one of the 
runners in the grass that may be easily overlooked. 
Boveri os — (Audubon). Leconte’s Sparrow. 
Common migra 
The first movement of Leconte’s Sparrows into the county is 
usually noticeable in late February (Feb. 25, 1916; Feb. 25, 
1917), but they are not numerous until two weeks later. BY 
the 15th to 20th of April they are gone, not to be seen again until 
late September. They remain until well into December (Dee- 
19, 1896, latest). 
These little sparrows are found on the high grassy prairies 
as well as in the open grassy bottom lands. They are not 5° 
easily overlooked as some of their more skulking kin, though 
they are great hiders and runners through the grass.
