nearby traffic noise filtered out Habitat: Riparian Adult bird ~50 m from Cooper's Hawk pair. Also ravens harassed the bird shortly after the recording. A Red-tail was also in the vicinity. The target bird was perhaps a bit agitated at my presence. No other black hawks were seen in the area.

something of a duet; I could see one adult perched on a side limb of a pinyon on the slope across the canyon, and I could see when it was calling (bill wide open) and that the softer vocalizations were not coming from it; noisy stream between me and them; interval shortened at 6:56, aiming the mic more at the less emphasized bird of the prior (but more stream noise); interval shortened at 7:42, more of the same, including the apparent second bird, which flew toward me and then probably reacted to seeing me after 10:56 with loud calls (best single vocalization) before landing on the hillside behind me and opposite the other bird;
