One of three pairs, with one bird feeding the other in apparent courtship. Paired audio recorded with a parabola.
观察细节
Three pairs. They came and left in twos, and in at least two of the three pairs, we observed one bird feeding the other. All appeared to be adults, so I suspect this was courtship behavior. Similar to the adjacent Chihuahuan Ravens but smaller and thinner-billed, with distinctive call like running a fingernail across the teeth of a comb, but more nasal.
