That ugly thing on the right is a eucalyptus tree. The Red-bellied Grackle area has a lot of pines and eucalyptus, both non-native. In fact when I was there in 2012 a giant eucalyptus forest near the entrance was being cut for timber. The grackles seem to have adapted, and are sometimes seen peeling and looking under the bark. I am not sure what keeps them confined to a small number of locations around 2000 meters.
A thrush-sized grackle which travels in small groups making non-musical sounds similar to other species of grackle. Largest population centers are in Antioquia, but can be found quite far from there.
