This post is really informative @agmoore, I think this bird posed perfectly so you could get good photos. On the other hand, I don't know much about birds either, but I think that here in Venezuela there is also a similar species, maybe they are of the same genus, I recognized it not only by the sample you share through the photos, but the video you left on Youtube made me clear my doubts when I heard the song. As a curious fact, here they usually nest in the trees of urban areas, when they already have offspring they pounce on the heads of all those people who pass near their nests, they do not peck but they get tangled in the hair of those who have long hair haha, it's kind of funny because when you hear their songs in an altered way you have to avoid the trees where they are or run. They are very beautiful birds, they are also reminiscent of crows because of their black color, a hug @agmoore.
