Another monkey. Much easier to see in the original 2mb format, you can C&P, then enlarge for detail. This is a spider monkey. We saw several of these, still in the Tortuguero area with this shot, although we saw them elsewhere in the country. These guys are tough to shoot without a good telephoto lens, as they spend most of their time high up in the trees.
The Tortuguero National Park info. is available online, BTW. Just Google. One thing I suspect you won't see is the large sign alongside the river where it warns in Spanish that you're about to enter a manatee zone, and to slow down.
As I was calculating the Spanish and translating in my head, I looked over and saw our guide had us sailing along at 50KPH, and that he didn't slow down a bit when we past that sign. Since most of our group spoke little or no Spanish, I asked him about that in Spanish, so as to not embarass the driver. Turns out there aren't any manatees in the area, according to the guide.
Sort of made me wonder why the hell they have a 50' high sign saying otherwise!
