A common bird but less frequent seen out in the open: The Green Oropendola.
When you spot 50 Crested Oropendola's you most likely see one Green Oropendola (Psarocolius viridis). Just like the Crested Oropendola's the Green one is also a large noisy bird (43 - 51 cm), but less frequent seen out in the open. And as their plumage almost resembles the green background it is also possible to miss them at first glance.
I've seen the Green Oropendola's usually high in a tree or well hidden between the foliage. They are also a bit shy when you try to get closer for a nice shot. This male Green Oropendola was too occupied by the Inga tree flowers so I was lucky that day. Besides flowers (nectar) they also prefer fruit and insects.
Like I said before this is a male Green Oropendola, recognizable by his blue icy eyes and his two tone bill. The female looks a bit duller.
