This one sounded loud and clear to me, despite my lousy phone recording. I'm leaning toward Steller's Jay myself, but, of course I'll never know for certain. Even comparing sonograms in the Macaulay Library didn't help very much. A hint, as I think about it after the fact, is that a hawk calling attention to itself would probably have attracted mobsters in that setting, but that didn't happen.

Good criteria. But typically the scream of a Red-tailed Hawk is stronger and more vigorous than the imitation of Steller's Jay. With practice the difference is discernable. Darrel

I used to think I could tell the difference, but have since decided that was hubris.  If it’s coming from high in the sky and there are no trees of any sort around, I definitely start looking for a red tail.  If it’s coming from deep in a tree AND is accompanied by typical Steller’s “chuckling,”  I’m content to smile to myself at what good mimics the jays are.  In any other situation, I withhold judgement.  I’ve proven myself wrong – both ways – too many times.

I recorded this call this morning in a wooded area where I have recently (including yesterday) seen Red-tailed Hawks, Steller's Jays and a Steller's Jay mimicking a Red-tailed Hawk. I am interested in others' opinions as to whether this is a hawk or a jay. My BirdNET app IDed it as Red-tailed Hawk -- "Almost certain" (Birdnet's highest degree of certainty; but sometimes incorrect). I filtered out some low-frequency noise, but have not otherwise fiddled with the sound.
