Mt. Cacaguatike, Dept., San Miguel, El Salvador Nov., 21, 1925 - Dec., 23, 1925 Yellow mouse The Yellow mice were caught only in the sub-tropical zone and usually on the banks of streams. Many were taken in traps set in the water for water mice. Traps set on rocks in the streams and baited with oatmeal were sure to catch a Yellow mice sooner or later. Nos. 10800, 10805, & 10840 we caught in a patch of tall rough bladed grass (grass patch described in Harvest mouse notes). Nos. 10845 & 10849 were caught in a corn [illegible] and bean patch where there was much glass; these traps were not more than 100 ft. from a stream. The trap were set in the grass, and at the base of corn stalks and bean vines, where there appeared to be signs of mice. Nos. 10867 & 10879 were caught in a stream where heavy grass lay over the water. This stream was bordered by brushy weed patches and old corn fields, being used for pasture land. Stomach contents were primarily plant pulp, however, some contained seed pulp. Ocolot No 10817 had a Yellow mouse in its stomach together with two other mice.
