Oropendolas know how to build these amazing nests without being taught but they do get better with practice. 

Where can you see them? You are most likely to see these nests in groups, high up in isolated trees around forest edges and clearings. They prefer remote trees. Deeper in the canopy predators can sneak up on them more easily without being seen. 

How are they made? The females weave the nests from grasses and palm leaf fibres, bark strips, roots and/or coconut fibres.  After weaving the attachment to the branch they build the door at the top and then weave down to form the bag beneath. The nests can be over 125cm long.  The best ones may survive and be reused for several years.
