Montezuma Oropendala

The oropendala is one of my favourite birds in Nicaragua. The first time I saw this bird, which was when this photo was taken, I was by a stream, and chunks of bark started to fall down all around me. I looked up and saw the bird tearing off the bark to access the insects underneath. Wow!

I was advised this is an oropendala nest, and the image fits, but I never saw an oropendala in the six weeks I've spent in this area.
