Well Trained Monkey 16 - Night Monkey Edition Mystery Cache

The cache is not at the posted coordinates, but is just a simple and enlightening puzzle away!

Nothing to worry about here…just a little trivia puzzle!

Night monkeys have big, brown eyes and therefore have increased ability to be active at night. Their ears are rather difficult to see, and their genus name, Aotus, means "earless" because of this. There is little data on the weights of wild night monkeys. From the figures that have been collected it appears males and females are similar in weight; the heaviest species are Azara's night monkeys at around 1,2(F)4 grams (2.(C)6 lb), and the lightest are Brumback's night monkeys which weigh between 455 and (E)75 grams (1.00 and 1.93 lb). The male is slightly taller than the female, measuring 34(B) and 341 millimetres ((A)3.6 and 13.(D) in), respectively.

While I am not local I visit the area every other weekend and can do any needed maintenance during that time.
