Having seen the near-total lack of wildlife pictures from Costa Rica, I decided to upload some of my own.
This was at the Monteverde Cloud Forest visitor centre- there were huge numbers of hummingbirds of many different species including the violet sabrewing (Costa Rica's largest species) as well as some tropical wasps and honeybees stealing the sugar water. If my assumptions are correct, this is the place where Jon Hall of mammalwatching.com tried (and failed) to see an olingo.
