1963 Reserve July 16 picked up notes on major tribes in Tilders, no bulldozing yet, lots of daisies flowering in trails, very little mustard still flowering, conium still greenish (red yellow), saw no cats, 1 pr final with young. July 17 watched from tower in pasture at 8 p.m., some mustard still flowering, Canada thistle almost dry, fig thistle still green, as well as bristly oaks tongue. Evening was cool and breezy, saw only 1 merotina briefly, but saw at least two mice several times. On one occasion there was a vigorous chase between two mice for about 15 feet, another? mouse covered several yards by moving along fallen weeds 6" or more above ground. During several observing periods lately, I have frequently seen 2 or more merotina within a foot or two of each other, but only one actual contact (face grooming). No chasing, and no squeals, hence no "fights". They are stripping the basal leaves of the big thistle; a browse line about 1 foot up on one of the thistles. One mouse climbed up onto a truncated thistle stalk about 8 inches high and nibbled at the mowed tops. I can find no trace of the top of this plant, so presumably all eaten. July 18 watched mice 7:45 to 8:45 p.m. (DST) in pasture, no wind, lots of mice, sometimes 5 in view at one time. On one occasion a mike was eating a thistle head on the ground, a half-grown mike came up beside it in contact (no scenting), and a third mouse was up in the thistle plant above them, a half-grown one extended considerable grooming around the base of the big thistle from which they have been stripping
