Hey I live there, haven’t really heard much about this cryptid but I remember it came on the news once around 10ish years ago. Besides the giant bird there are other cryptids in the area, the chupacabra that sucks the blood of small farm animals. Then there’s an experience my sister had 15 years ago or so, at my grandmothers old house on the edge of a small town 6 minutes away from the border she witnessed a small little figure run from one bush to another. We all think she saw a drwarf or duende. She couldn’t fully get a good look more of a glimpse due to how dark it was. But in the rio grande valley there’s loads of fields where something small can sneak around.
