|Costa Rica and the continental bridge :|
I have two reasons to show this picture of a flying Central American Squirrel Monkey (Saimiri oerstedii, Barizo Dorsirrojo, Zentralamerikanischer EichhĂśrnchenaffe. Cebidae) :
1) The shot shows the difficulty of photography in a forest with lots of tree branches, little light, the animals often high up in the trees - and then you should focus on the eyes of the beast :-) Note the fact that Squirrel monkeys don't have a gripping tail as most other New World primates do.
2) Central America is, geologically speaking, a young continental bridge. During the breakup of the supercontinent Pangea South America drifted off, isolated by oceans on all sides. The mammal fauna of the time in South America consisted of Marsupials and some early Placentalians , whose descendants are the Ant eaters, the Sloths and the Armadillos, but not the Primates. Primates originated according to fossil finds in Africa, the immigration of early Primates to South America is an unresolved mystery (one thinks of huge rafts after tropical storms ...). When the Central American bridge was formed between North and South America, a faunal exchange took place and Primates settled in Central America as well as the mentioned Marsupials, Sloths, Armadillos and Ant eaters. From the North the Cats, Ungulates and Rodents arrived. Today Costa Rica harbors four species of Primates excluding Man.

Hi Dietrich,a very difficult pic,what a timing and what a quality,great way to show us this species that reminds a bit the lemuri that i seen in Madagascar many years ago,well done! Have a nice day and thanks,Luciano
Excellent timing and even facing your camera upward. I've seen this Squirrel Monkey only in a documentary. Good details and well placed. Difficult shot to me.
Thanks for sharing,
Regards and have a nice weekend,
