Tonight after a great day working with colleagues at the Santa Fe Institute, Joe Bak-Coleman went for a hike. As we headed back to the car, A huge flock of birds headed up Santa Fe Canyon; I knew their squeaky caws before I even saw them. It was a group of at least 100 pinyon jays heading to roost. I've never seen anything like it. I am so happy they are thriving here. 2/2
