This spring we saw and welcomed the early return of two Swainson's Hawk (SWHA) couples to Sutters Landing Park and right away they started nest building, which is an ongoing process! As you can see below, one couple built in a Black Locus tree while it still had fragrant spring flowers on it. That’s the first nest I’ve ever see built in this species of tree and also this far down river!
The other couple choose to build in a tall riverside Cottonwood tree, as all other Swainson's Hawks have.
