A family of howler monkeys, we’re told, usually consists of a male, a few females, and the offspring. The family that lives in the jungle which surrounds our hotel inside the Tikal, Guatemala Archeological Preserve, consists of seven that I counted. They make this ungodly loud roaring sound at irregular intervals. One guide told us they do this to announce their territory and to warn other howlers to stay away. This guy and his entire family of woke us up a couple of times last night–at 2 a.m. and again at 4. Here he is at 7 a.m. trying to look innocent.
