Oooooh these guys make the strangest and most bizarrely beautiful songs. It sounds like… Raindrops on a steel drum? Or a tape being rewound? It’s hard to describe. The Cornell eBird lab has great recordings in the link below.
They also make crazy nests that hang like straw teardrops in the tree. I remember seeing them when I travelled in South America and thinking they were man-made birdhouses. Thanks for posting the pics, I had forgotten how much I love these birds!
That sound is quite far out – sounds quite mechanical but then ends with a very tropical sounding flourish. Your link has also a good map, worth looking at that too.
The olive oropendola is sometimes split into two species, the western olive oropendola (P. yuracares) and the eastern Pará oropendola (P. bifasciatus), but the subspecies P. y. neivae is widely recognized as a hybrid swarm, and the vast majority of authorities consider them a single species.
Oh this is interesting, It’s the first time i’ve seen one like this. Oropendolas usually come to my backyard, but they are pretty different from the Olive Oropendolas. Did a quick research, and they seem to be from the Montezuma species. Btw, where are the Olive ones from?
From a map I saw, it appears to be the northern half of the Amazon basin. There are a number of oropendola species, all rather attractive in my opinion. I actually don’t think this species is the most colorful but I love the rich olive and brown plumage and that pink wattle and orangey end of its beak.
