The Noctilis must have recently molted all are a very bright orange in contrast to the dull yellow brown we usually see. Colur similar colored Noctilis a year ago, in the eastern region. On the smaller pond, rapidly drying up there only about 10-15 ft long $ 6' web, there were so many Noctilios that after the full web right after dark, their feet made continuous splashing cloud - they hit the water hard. In the late afternoon, but before dark, Pet & I shot several guinea pigs along the road & the edge of the water (caring to drink?). They are abundant. Pile brush, ittony tusks, etc - all underlain, by trails. The white urine stains $ the droppings are everywhere. Seem to be diurnal or at least we never see them at night. Weather: clear, wind has switched to (from) N #W blowing, but calm in evening. Humid, too - mini- temp around 10°C.
