I recalled that when I had the hawk-nuthatch standoff the other day, the reason I became aware of the hawk's presence, was that the robins were calling. Their warning for a bird predator is different than when it's a cat in the yard. It's a fast "chee-chee-chee-chee"....fairly high-pitched. I heard that call and looked out and saw the hawk landing in the spruces.
Robins' cat warning is a persistent paced, "chip, chip, chip, chip." Not to sound too formulaic, but - it's almost a "chirp, chirp, chirp!" very sharp and short.
